Detailed Notes (Comprehensive but Skimmable)
Context: Pre-Colonial Labor Patterns
Before Spanish colonization, indigenous societies in the Americas had their own labor systems and social hierarchies. The Aztec Empire extracted tribute and labor from conquered peoples through a tribute system, while the Inca used the mita system requiring subjects to provide labor for state projects. These pre-existing patterns of coerced labor meant that Spanish colonizers could adapt indigenous institutions to their own purposes rather than creating entirely new systems. In Europe, feudalism had established traditions of bound labor, where peasants owed service to lords. African slavery already existed in small numbers in Iberia and Atlantic islands, where Portuguese had established sugar plantations using enslaved labor. These pre-colonial patterns provided models that Spanish colonizers would adapt and intensify in the Americas.
What Happened: Spanish Colonial Labor Systems
The Encomienda System: Following conquest, Spain faced a fundamental problem: how to extract wealth from American colonies while maintaining control over indigenous populations. The encomienda system, established in the early 1500s, attempted to solve this problem by granting conquistadors and colonists authority over Native Americans in specific geographic areas. In theory, encomenderos (grant holders) received the right to demand labor and tribute from indigenous peoples in exchange for providing protection and Christian religious instruction. This paternalistic justification claimed to benefit Native Americans while serving Spanish interests.
In practice, the encomienda became brutal exploitation. Encomenderos forced Native Americans to work in mines, on plantations, and in households with minimal or no compensation. Working conditions were horrific—indigenous miners at places like Potosí died from overwork, accidents, malnutrition, and mercury poisoning used in silver processing. The concentration of Native populations on encomiendas accelerated disease transmission, as European diseases spread rapidly through communities living and working in close quarters. The encomienda combined with epidemic disease to kill millions of Native Americans within decades.
The encomienda system sparked intense debate in Spain about the morality of indigenous treatment. Dominican friar Bartolomé de las Casas documented atrocities and advocated for Native American rights, arguing that indigenous peoples were rational beings entitled to humane treatment. His advocacy contributed to the Spanish Crown issuing the New Laws of 1542, attempting to reform the encomienda by prohibiting enslavement of Native Americans and limiting encomenderos' authority. However, these reforms faced fierce resistance from colonists whose wealth depended on indigenous exploitation, and enforcement remained weak. The encomienda gradually evolved into other systems as Native American populations collapsed.
Repartimiento and Mita Systems: As the encomienda's worst abuses became apparent and Native populations declined dramatically, Spain modified its labor systems. The repartimiento (called cuatequil in Mexico) required indigenous communities to provide a percentage of their adult males for temporary labor drafts on Spanish projects—mining, agriculture, construction. Unlike encomienda, repartimiento theoretically involved payment and limited labor duration, though in practice wages were minimal and working conditions remained brutal.
In the Andean region, Spain adapted the Inca mita system, which had required subjects to provide labor for the state. The Spanish mita forced indigenous communities to send a quota of men to work in silver mines, particularly at Potosí. Men might work for months or a year in the mines before returning home, but mortality rates were extraordinarily high. The mita at Potosí became notorious for its brutality, with indigenous workers forced deep underground in dangerous conditions, exposed to toxic mercury, and suffering from accidents and lung diseases. Many workers never returned home, and communities were devastated by the loss of adult males.
The Turn to African Slavery: The demographic catastrophe of Native Americans—with populations declining 80-95% from disease—created severe labor shortages in Spanish colonies. As indigenous populations collapsed, Spanish colonizers increasingly turned to importing enslaved Africans. African slavery had several perceived advantages from the Spanish perspective: Africans had some immunity to European and tropical diseases, they were removed from their homelands making resistance more difficult, and a lucrative transatlantic slave trade had already developed for Portuguese sugar plantations in Brazil and Atlantic islands.
The transition to African slavery was gradual but transformative. By the late 1500s, enslaved Africans worked in Caribbean sugar plantations, Mexican silver mines, and as domestic servants throughout Spanish America. Unlike the encomienda or repartimiento, which theoretically recognized Native Americans as free subjects, African slavery was explicitly racial and heritable—enslaved status passed from mother to child. This established racial slavery as a defining feature of the colonial Americas, with profound consequences for centuries to come. The Spanish colonial economy came to depend on a mix of indigenous forced labor (where Native populations survived) and African slavery (particularly in mining and plantation agriculture).
The Casta System: As biological and cultural mixing occurred in Spanish colonies, Spain developed the casta system to classify people by racial ancestry and establish a rigid social hierarchy. This system created multiple racial categories beyond simple European, indigenous, and African divisions. At the top were peninsulares (Spanish-born in Spain) who held the highest political and religious offices. Below them came criollos (people of Spanish ancestry born in the Americas) who owned land and held lower offices but resented their subordination to peninsulares. Mestizos (Spanish-Native American ancestry) occupied intermediate positions, working as artisans, small merchants, and overseers. Mulattos (Spanish-African ancestry) and zambos (Native American-African ancestry) ranked lower still. At the bottom were indigenous peoples and enslaved Africans.
The casta system was more complex than this simplified hierarchy suggests. Spanish officials created detailed classifications with specific terms for different ancestry combinations, sometimes distinguishing 16 or more categories. A person's casta determined legal rights, tax obligations, marriage restrictions, residential locations, and economic opportunities. The system attempted to maintain Spanish dominance by limiting social mobility and keeping wealth and power concentrated among those with Spanish ancestry. However, the casta system was never entirely rigid—wealthy mestizos sometimes purchased certificates of whiteness (gracias al sacar), and in practice, appearance, wealth, and behavior could influence racial classification. Still, the system established racial hierarchy as foundational to colonial society, with consequences extending far beyond the colonial period.
Why It Matters: Historical Significance
Spanish colonial labor systems and the casta system established patterns that profoundly shaped subsequent American history. The exploitation of indigenous peoples through encomienda, repartimiento, and mita systems, combined with disease, killed millions and disrupted Native American societies in ways that persist today. These systems demonstrated how colonizers would prioritize wealth extraction over indigenous welfare, establishing extractive economies that enriched Spain while impoverishing colonies—a pattern affecting Latin American development for centuries.
The turn to African slavery in response to Native American population collapse established racial slavery as fundamental to the American colonial economy. This decision to make slavery explicitly racial and heritable created a system that would expand dramatically in subsequent periods, particularly in the plantation South. The association of blackness with slavery and the development of racial hierarchies justifying exploitation would have devastating consequences lasting through emancipation, Jim Crow, and continuing to the present.
The casta system's rigid racial hierarchies established social stratification based on ancestry that persisted long after independence. By linking race to legal status, economic opportunity, and social position, the casta system created societies where inequality was not merely economic but racialized. Light-skinned people of European ancestry maintained political and economic dominance, while indigenous peoples and people of African ancestry faced systematic discrimination. These patterns influenced social structures throughout the Americas, including racial attitudes in territories that would become the United States.
For APUSH essays, this topic provides essential evidence for arguments about the origins of racial slavery, comparison of labor systems (indigenous forced labor vs. African slavery; encomienda vs. later indentured servitude or plantation slavery), causation (demographic catastrophe leading to African slavery), and continuity and change (how Spanish colonial patterns persisted or transformed). Understanding these systems is fundamental to analyzing all subsequent American history involving race, labor, and inequality.
Continuity vs. Change (CCOT)
What Changed: Spanish colonization fundamentally transformed labor systems and social hierarchies in the Americas. Pre-colonial indigenous tribute systems were adapted into the far more brutal encomienda, creating systematic exploitation on an unprecedented scale. The introduction of African slavery represented a complete break from previous patterns—establishing racial, heritable slavery as opposed to various forms of indigenous servitude or bondage. The creation of the casta system imposed entirely new racial categories and hierarchies, as biological and cultural mixing produced mestizo, mulatto, and other mixed populations that had not existed before contact. Economic patterns shifted from indigenous subsistence and tribute economies to Spanish extraction economies focused on mining precious metals and producing cash crops for export. The demographic catastrophe meant that by the late 1500s, the Americas had fundamentally different population compositions than in 1491, with millions of indigenous people dead and increasing numbers of Africans and mixed-race people.
What Persisted: Despite massive disruption, some patterns showed continuity. Spanish colonizers adapted pre-existing indigenous labor systems rather than creating entirely new ones—the Incan mita was modified rather than replaced, and tribute obligations continued though redirected to Spanish rather than indigenous rulers. Indigenous communities maintained internal social structures and some degree of self-governance where they avoided direct Spanish control. The basic pattern of elites extracting labor from subordinate populations persisted, even as the identity of elites changed from indigenous rulers to Spanish colonizers. Racial hierarchies existed before Spanish arrival—Aztec society distinguished between nobility and commoners, and various indigenous groups maintained ethnic distinctions—though the Spanish racialized these hierarchies in new ways. Agriculture continued to be the foundation of most colonial economies, though now organized around Spanish demands. Native Americans continued to resist exploitation through open rebellion, subtle resistance, and attempts to preserve cultural practices despite Spanish pressure.
Complexity: Tensions & Historical Debates
- Protection vs. Exploitation: Spanish colonial ideology claimed that indigenous peoples needed Spanish protection and Christian instruction, justifying the encomienda system as beneficial to Native Americans. However, the reality was brutal exploitation killing millions. This tension between stated ideals and actual practices raises questions about Spanish motivations—were colonizers genuinely conflicted about moral obligations, or did they cynically use religious justifications for economic greed? The debate between Bartolomé de las Casas and Juan Ginés de Sepúlveda about indigenous rights reveals that some Spaniards genuinely grappled with moral questions, even as colonial practices continued largely unchanged. This complexity challenges simple narratives of evil colonizers while not excusing systematic exploitation.
- Slavery vs. Servitude: Historians debate whether to classify the encomienda system as slavery or a form of serfdom/bound labor. Legally, Native Americans under encomienda were subjects of the Spanish crown, not property that could be bought and sold like enslaved Africans. However, the practical difference was minimal—indigenous people were forced to work under brutal conditions with no freedom to leave, and many died from the exploitation. This debate affects how we characterize Spanish colonization and compare it to other colonial systems. It also relates to questions about when and how racial slavery became distinct from other forms of unfree labor in the Americas.
- Rigidity vs. Fluidity of Racial Categories: The casta system appears to be a rigid hierarchy with fixed categories, but scholars debate how consistently it operated in practice. While the system legally defined status by ancestry, evidence shows that wealth, behavior, appearance, and social connections could influence racial classification. Some people successfully "passed" as higher castas, and wealthy mestizos sometimes purchased legal recognition as Spanish. This suggests the casta system was simultaneously rigid (in establishing racial hierarchy as fundamental) and fluid (in allowing some individual mobility). Understanding this complexity is important for avoiding oversimplified views of colonial racial systems while recognizing their real oppressive effects.

Timeline: Development of Spanish Colonial Labor and Caste Systems
Encomienda System Established: Following Caribbean colonization and conquest of mainland, Spain grants encomenderos authority over indigenous peoples who must provide labor and tribute. System rapidly becomes brutal exploitation.
First Critiques of Encomienda: Dominican friar Antonio de Montesinos preaches against mistreatment of indigenous peoples. Bartolomé de las Casas begins documenting atrocities, sparking debates in Spain about colonial practices.
Encomienda Expands After Conquests: Following conquests of Aztec and Inca empires, encomienda system spreads throughout mainland Spanish America. Disease and exploitation kill millions of indigenous people.
New Laws Attempt Reform: Spanish Crown issues New Laws prohibiting enslavement of Native Americans and attempting to limit encomienda abuses. Colonial resistance leads to weak enforcement and limited actual improvement.
Potosí Silver Discovery and Mita: Discovery of massive silver deposits at Potosí leads to expansion of mita forced labor system. Indigenous men forced to work in brutal mining conditions; mortality rates extremely high.
Repartimiento Replaces Encomienda: As indigenous populations collapse and encomienda's brutality becomes unsustainable, Spain implements repartimiento labor drafts. System remains exploitative despite theoretical improvements.
Valladolid Debate: Spanish theologians Bartolomé de las Casas and Juan Ginés de Sepúlveda debate indigenous rights and nature. Las Casas argues Native Americans are rational beings deserving protection; Sepúlveda justifies conquest and forced conversion.
Expansion of African Slavery: As Native American population collapse creates labor shortages, Spanish increasingly import enslaved Africans. Racial slavery becomes established in mining, plantations, and domestic service throughout Spanish America.
Casta System Crystallizes: As biological and cultural mixing produces diverse populations, Spanish develop elaborate casta system classifying people by ancestry. Racial hierarchy determines legal rights, social status, and economic opportunities.
Mixed Labor System Emerges: By end of Period 1, Spanish colonies operate with mixed labor system: mita and repartimiento where indigenous populations survive; African slavery particularly in mining and plantation agriculture; casta system organizing social hierarchy.
Historical Thinking Skills (Topic-Specific)
Causation: Causes & Effects of Spanish Labor Systems
Causes of Spanish Colonial Labor Systems:
- Economic motivations: Spanish desire to extract wealth (particularly silver) from colonies required large labor forces for mining and agriculture
- Demographic catastrophe: Disease killed 80-95% of Native Americans, creating severe labor shortages that drove turn to African slavery
- Pre-existing models: Indigenous tribute systems (Aztec, Inca mita) provided templates Spanish adapted; European feudalism and African slavery offered other models
- Lack of alternatives: Spanish colonists couldn't recruit enough European labor; indigenous populations either died from disease or resisted; African slavery appeared to solve labor crisis
- Religious justifications: Catholic ideology claiming duty to convert indigenous peoples provided moral cover for exploitation through encomienda
Effects of Spanish Labor Systems:
- Mass indigenous deaths: Encomienda, mita, and repartimiento, combined with disease, killed millions; some regions lost nearly entire Native populations
- Establishment of racial slavery: Turn to African slavery created explicitly racial, heritable system that would expand throughout Americas and persist for centuries
- Creation of racial hierarchies: Casta system institutionalized racism, linking ancestry to legal status and economic opportunity with consequences lasting beyond independence
- Spanish wealth accumulation: Labor exploitation enabled Spain to extract enormous wealth, particularly silver, though this enriched Spain while impoverishing colonies
- Social stratification: Labor systems and casta hierarchy created deeply unequal societies with rigid class divisions based on race
- Cultural mixing: Exploitation and colonization led to biological and cultural blending, creating mestizo, mulatto, and other mixed populations with distinct identities
- Extractive economies: Focus on mining and cash crop export rather than diversified development established economic patterns affecting Latin American development for centuries
Causal Chain Example: Spanish conquest → need for labor to extract wealth → encomienda system exploiting indigenous peoples → European diseases spread through concentrated populations → 80-95% Native American mortality → severe labor shortage → Spanish turn to African slavery → establishment of racial slavery as fundamental to colonial economy → creation of casta system to organize increasingly diverse colonial society → institutionalization of racial hierarchy linking ancestry to status.
Continuity & Change Over Time
| Aspect | What Changed | What Stayed the Same |
|---|---|---|
| Labor Systems | Encomienda replaced indigenous tribute systems with more brutal exploitation; introduction of African slavery represented new form of racial, heritable bondage; formal mita and repartimiento systems structured forced labor | Pattern of elites extracting labor from subordinate populations continued; tribute and labor obligations persisted though redirected to Spanish; some indigenous communities maintained traditional work patterns |
| Social Hierarchy | Casta system created entirely new racial categories and hierarchies; mixture of populations produced mestizos, mulattos, zambos not existing before; Spanish-born peninsulares displaced indigenous elites as ruling class | Social stratification continued with elites dominating subordinate groups; importance of ancestry in determining status persisted; hierarchical social organization remained fundamental to society |
| Legal Status | New legal distinctions based on race emerged; enslaved Africans defined as property unlike indigenous peoples theoretically recognized as Spanish subjects; casta determined rights and obligations | Unequal legal treatment based on social status continued; subordinate groups faced legal restrictions on movement, marriage, occupation regardless of whether indigenous, African, or mixed |
| Economic Patterns | Shift from subsistence and regional trade to extraction economy focused on silver mining and export; commercial agriculture for Spanish markets replaced indigenous farming; money economy increased | Agriculture remained economic foundation; local and regional trade continued; many indigenous communities maintained subsistence farming alongside tribute obligations |
| Population Composition | Native American populations collapsed by 80-95%; Spanish immigration; forced African migration through slavery; emergence of large mixed-race populations | Indigenous peoples remained majority in many regions throughout Period 1; Native American cultural and linguistic diversity persisted despite demographic catastrophe |
| Resistance Patterns | Nature of resistance shifted to opposing Spanish colonizers rather than rival indigenous groups; armed rebellions targeted Spanish rather than other Native Americans | Indigenous peoples continued resisting exploitation through rebellion, work slowdowns, flight, and cultural preservation; pattern of subordinate groups resisting elite control persisted |
Why Patterns Changed or Persisted: Changes resulted primarily from Spanish colonization imposing new economic goals (wealth extraction for Spain), new population compositions (African slavery, mestizo emergence), and new ideologies (racial hierarchies justifying exploitation). The demographic catastrophe from disease fundamentally transformed indigenous societies by killing most people, enabling Spanish dominance that might otherwise have been impossible. However, continuities persisted because Spanish colonizers often adapted rather than replaced indigenous institutions (mita from Inca system), and because fundamental patterns of elite-subordinate relations transcended changes in elite identity. Geographic isolation meant some indigenous communities avoided direct Spanish control, maintaining traditional practices. The basic human patterns of social hierarchy, labor extraction, and resistance to exploitation showed continuity even as specific forms changed.
Comparison: Encomienda vs. African Slavery
| Dimension | Encomienda System | African Slavery |
|---|---|---|
| Legal Status | Native Americans theoretically remained free subjects of Spanish crown; not property that could be bought and sold | Enslaved Africans defined as property; could be bought, sold, inherited like any other commodity |
| Racial Basis | Not explicitly racial—based on conquest and Spanish authority over indigenous peoples in specific territories | Explicitly racial—slavery associated with African ancestry and blackness; racial justifications developed for why Africans should be enslaved |
| Heritability | Not heritable—children of people under encomienda not automatically subject to same obligations | Heritable through maternal line—children of enslaved mothers born into slavery regardless of father's status |
| Justification | Paternalistic ideology—claimed to protect Native Americans while providing Christian instruction; conquistadors rewarded for conquest | Racial ideology—increasingly claimed Africans were naturally inferior and suited for slavery; economic justifications about labor needs |
| Duration | Theoretically temporary grants, though in practice often multi-generational; gradually evolved into other systems as reformed | Permanent status—enslaved Africans and descendants remained enslaved unless specifically freed (manumission) |
| Scope of Control | Encomenderos controlled labor of indigenous peoples in specific geographic areas; Native Americans remained in their communities | Enslavers had complete control over enslaved individuals; Africans forcibly removed from homelands and transported across Atlantic |
| Mortality Impact | Extremely high mortality from combination of brutal labor conditions and European diseases; millions died | High mortality from Middle Passage and brutal working conditions, but Africans had some immunity to European/tropical diseases |
| Response/Reform | Sparked significant debate in Spain; New Laws attempted reform; system gradually modified due to moral objections and population collapse | Generally accepted by Spanish colonizers and officials; some critique but minimal reform efforts compared to encomienda |

FAQ
Legally, the encomienda system and slavery differed significantly, though in practice the distinction was often minimal. Under encomienda, Native Americans remained free subjects of the Spanish crown who owed labor and tribute to Spanish colonists in exchange for protection and Christian instruction—they were not property that could be bought and sold. Slavery, particularly African slavery, made people property that could be bought, sold, and inherited. Slavery was explicitly racial and heritable (children born into slavery), while encomienda was not technically racial or heritable. However, for indigenous people experiencing forced labor unto death under encomienda, the practical difference from slavery was negligible. Both systems involved brutal exploitation, and the theoretical legal protections for Native Americans under encomienda meant little when enforcement was weak and colonists prioritized profit over indigenous welfare.
Spain turned to African slavery primarily because of the demographic catastrophe that killed 80-95% of Native Americans through disease. This created severe labor shortages in colonies dependent on labor-intensive mining and plantation agriculture. Africans had several perceived advantages from the Spanish colonial perspective: they had some immunity to European and tropical diseases, making mortality rates lower than for Native Americans; they were removed from their homelands making organized resistance more difficult; and an established transatlantic slave trade already existed from Portuguese operations in Brazil and Atlantic islands. Additionally, Spanish debates about indigenous rights and the New Laws of 1542 created (weak) legal protections for Native Americans that didn't apply to Africans. The combination of indigenous population collapse and availability of enslaved Africans made African slavery appear to solve the colonial labor crisis, establishing racial slavery as foundational to the American colonial economy.
The casta system was a racial hierarchy in Spanish colonies that classified people by ancestry and determined their legal status, rights, and social position. At the top were peninsulares (Spanish-born), followed by criollos (American-born Spanish), mestizos (Spanish-Native American), mulattos (Spanish-African), indigenous peoples, and enslaved Africans at the bottom. The system created many additional categories for different ancestry combinations. A person's casta determined where they could live, whom they could marry, what occupations they could pursue, how much they paid in taxes, and what legal rights they possessed. The system attempted to maintain Spanish dominance by limiting social mobility and keeping wealth and power concentrated among those with Spanish ancestry. While theoretically rigid, in practice some fluidity existed—wealth, appearance, and social connections could influence classification, and some wealthy mestizos purchased legal recognition as Spanish. Despite this fluidity, the casta system established racial hierarchy as fundamental to colonial society, with consequences persisting long after independence.
The mita was a forced labor system in the Andean region that the Spanish adapted from the Inca practice of requiring subjects to provide labor for the state. Under Spanish control, indigenous communities had to send a quota of adult men to work in silver mines, particularly at Potosí, for extended periods (months or a year). The mita was extraordinarily deadly because miners worked deep underground in dangerous conditions with frequent accidents and cave-ins, were exposed to toxic mercury used in silver processing (causing mercury poisoning and lung diseases), suffered from malnutrition and overwork, and faced brutal treatment from Spanish overseers. Mortality rates were so high that many workers never returned home, and communities lost a generation of adult males. The mita at Potosí became notorious as one of the most brutal labor systems in colonial history, with thousands of indigenous people dying to extract silver that enriched Spain while impoverishing colonies.
Bartolomé de las Casas was a Dominican friar who documented Spanish atrocities against indigenous peoples and became the most prominent advocate for Native American rights in the 16th century. Initially a colonist who owned Native Americans under encomienda, Las Casas underwent a moral conversion and spent decades exposing the brutal exploitation and arguing that indigenous peoples were rational beings deserving humane treatment. His writings influenced the Spanish Crown to issue the New Laws of 1542 attempting to reform the encomienda. Las Casas is important because he demonstrates that some Spaniards genuinely grappled with the moral implications of colonization and opposed exploitation, complicating simple narratives about colonial motivations. However, his advocacy also reveals contradictions—he initially suggested African slavery as an alternative to indigenous labor (later regretting this), showing how even opponents of one form of exploitation could accept another. His debates with Juan Ginés de Sepúlveda represent fundamental disagreements about indigenous rights and the justifications for conquest.
When comparing Spanish labor systems, organize around clear categories: legal status (encomienda treated Native Americans as subjects, slavery made Africans property), racial basis (encomienda not explicitly racial, slavery tied to African ancestry), heritability (slavery passed through maternal line, encomienda obligations not inherited), justifications (encomienda claimed Christian protection duty, slavery increasingly justified by racial ideology), duration (encomienda theoretically temporary, slavery permanent unless freed), and reform efforts (encomienda faced significant Spanish debate and New Laws, slavery generally accepted). Always explain why differences existed—encomienda adapted conquest relationships, slavery responded to labor shortage after demographic catastrophe. Compare effects on different groups—millions of Native Americans died under encomienda combined with disease, enslaved Africans faced permanent bondage but had some disease immunity. Note evolution—encomienda modified into repartimiento and mita, while African slavery expanded. Use specific examples like Potosí mita or Caribbean sugar plantations rather than generalizations.
Spanish colonial labor systems and the casta system had profound long-term consequences that shaped Latin American and U.S. history for centuries. The exploitation of indigenous labor through encomienda, mita, and repartimiento, combined with disease, killed millions and disrupted Native American societies in ways that persist today, including poverty, marginalization, and loss of cultural knowledge. The turn to African slavery established racial slavery as fundamental to American economies, a system that would expand dramatically in subsequent periods and persist until the 19th century, creating patterns of racial inequality lasting to the present. The casta system's racial hierarchies institutionalized racism by linking ancestry to legal status and opportunity, creating societies where light-skinned people of European ancestry maintained dominance while indigenous peoples and those of African ancestry faced systematic discrimination. These racial hierarchies persisted after independence as Latin American nations maintained social stratification based on race. The extractive economies focused on mining and cash crop exports rather than diversified development established economic patterns that contributed to Latin American underdevelopment compared to North America. For the United States, Spanish colonial patterns influenced racial attitudes in territories acquired from Mexico and established precedents for racial slavery that would define Southern plantation economies.
