Brief History of Slavery in America
Nearly 75 percent of people who arrived in America from Europe and Africa before 1776 were immigrants in bondage. Those from Africa almost always arrived enslaved. Those from Europe were often convicts, indentured servant apprentices, or became indentured servants to pay for the cost of their ocean crossing. In colonial times indentured servitude as an apprentice was considered the normal way to learn a trade (part of growing up), or a normal option for paying a large debt.
In 1619 a Dutch ship blown off course came looking for fresh water near Jamestown, Virginia. At Jamestown the Dutch sold 20 of the African slaves they had captured from a Spanish ship originally bound for Mexico. These were the earliest known African immigrants to arrive in what is now the United States. It was the custom of that time to free servant-slaves after seven years.
Caribbean and Brazilian plantations (95 percent of the trans-Atlantic slave trade) usually grew sugar and few slaves survived there for seven years. In America (five percent of the slave trade) slaves lived longer and had children. In the thirteen British-American colonies a milder climate and better working conditions growing tobacco, cotton, hemp, and indigo allowed slaves to live long enough to be freed. But the institution of lifetime chattel slavery applied to people of African descent was slowly accepted and developed when owners were reluctant to free such valuable labor to compete with their former owners. This form of slavery was formally legalized first in British-America in 1654.
All 13 British-American colonies participated in the slave trade before 1780. In the 1750s a slavery abolitionist movement began and grew stronger. Vermont was the first to abolish slavery in 1777 and by 1804 all individual states north of the Mason-Dixon line had gradually ended slavery. The Northwest Ordinance of 1787 was a federal law that prohibited slavery north of the Ohio River. Slave labor works best when the assigned task is relatively simple, such as large scale agriculture. Slavery in increasingly industrialized America was becoming too expensive until the invention of the cotton gin in 1793. A healthy young adult male slave was worth about two years wages, so most owners considered freeing slaves an economic hardship. The Constitution of the United States permitted the outlawing of the importation of slaves starting in 1808, but the internal slave trade continued until the end of the Civil War and the Thirteenth Amendment prohibited chattel slavery in 1865.

Registers of Slaves and Freedmen and Manumission Papers
By the time of start of the Civil War in 1861 about ten percent of African Americans were free. Most free African Americans carried their own papers, but these could be stolen. In order to distinguish between slaves, runaways, and free African Americans, many counties or states in the upper South, and border states kept one or more sets of registers or papers. Some had registers of slaves. Some kept registers of blacks, freedmen, "free men of color," or "free negroes." Some kept copies of manumission papers of people freed from enslavement. To find these kinds of registers or papers look in county courthouse records. They are most likely found in the court papers, or among the land and property deeds, or occasionally in probate records, or even with taxation records. Sometimes these kinds of records are found at state libraries, archives, or historical soci
The Slave Trade Registers
The Constitution allowed the outlawing of the importation of slaves to the United States after 1808. Between then and the Civil War the internal slave trade became an important business in the Southern United States. Most states regulated the slave trade. A few kept records of slave traders and their businesses. Look for such business registers at state libraries, archives, historical societies, or county courthouses.
Trans-Atlantic Slave Trade Database
The Trans-Atlantic Slave Trade Database Internet site contains references to 35,000 slave voyages, including over 67,000 Africans aboard slave ships, using name, age, gender, origin, and place of embarkation. The database is about the slave trade between Africa, Europe, Brazil, the Caribbean, and the United States.
