Slavery in Africa in the context of "European colonies"

The Atlantic slave trade or transatlantic slave trade involved the transportation by slave traders of enslaved African people to the Americas. European slave ships regularly used the triangular trade route and its Middle Passage. Europeans established a coastal slave trade in the 15th century, and trade to the Americas began in the 16th century, lasting through the 19th century. The vast majority of those who were transported in the transatlantic slave trade were from Central Africa and West Africa and had been sold by West African slave traders to European slave traders, while others had been captured directly by the slave traders in coastal raids. European slave traders gathered and imprisoned the enslaved at forts on the African coast and then brought them to the Western hemisphere. Some Portuguese and Europeans participated in slave raids. As the National Museums Liverpool explains: "European traders captured some Africans in raids along the coast, but bought most of them from local African or African-European dealers." European slave traders generally did not participate in slave raids. This was primarily because life expectancy for Europeans in sub-Saharan Africa was less than one year during the period of the slave trade due to malaria that was endemic to the African continent. Portuguese coastal raiders found that slave raiding was too costly and often ineffective and opted for established commercial relations.

The colonial South Atlantic and Caribbean economies were particularly dependent on slave labour for the production of sugarcane and other commodities. This was viewed as crucial by those Western European states which were vying with one another to create overseas empires. The Portuguese, in the 16th century, were the first to transport slaves across the Atlantic. In 1526, they completed the first transatlantic slave voyage to Brazil. Other Europeans soon followed. Shipowners regarded the slaves as cargo to be transported to the Americas as quickly and cheaply as possible, there to be sold to work on coffee, tobacco, cocoa, sugar, and cotton plantations, gold and silver mines, rice fields, the construction industry, cutting timber for ships, as skilled labour, and as domestic servants. The first enslaved Africans sent to the English colonies were classified as indentured servants, with legal standing similar to that of contract-based workers coming from Britain and Ireland. By the middle of the 17th century, slavery had hardened as a racial caste, with African slaves and their future offspring being legally the property of their owners, as children born to slave mothers were also slaves (partus sequitur ventrem). As property, the people were considered merchandise or units of labour, and were sold at markets with other goods and services.

The African Pygmies (or Congo Pygmies, variously also Central African foragers, African rainforest hunter-gatherers (RHG) or Forest People of Central Africa) are a group of ethnicities native to Central Africa, mostly the Congo Basin, traditionally subsisting on a forager and hunter-gatherer lifestyle. They are divided into three roughly geographic groups:

• The western Bambenga, or Mbenga (Cameroon, Gabon, Republic of the Congo, Central African Republic),
• the eastern Bambuti, or Mbuti, of the Congo basin (DRC)
• the central and southern Batwa, or Twa (Rwanda, Burundi, DRC, Tanzania, Uganda, Zambia, Angola and Namibia). The more widely scattered (and more variable in physiology and lifestyle) Southern Twa are also grouped under the term Pygmoid.

They are notable for, and named for, their short stature (described as "pygmyism" in anthropological literature). They are assumed to be descended from the original Middle Stone Age expansion of anatomically modern humans to Central Africa, albeit substantially affected by later migrations from West Africa, from their first appearance in the historical record in the 19th century limited to a comparatively small area within Central Africa, greatly decimated by the prehistoric Bantu expansion, and to the present time widely affected by enslavement at the hands of neighboring Bantu, Ubangian and Central Sudanic groups.

African Americans, also known as Black Americans and formerly called Afro-Americans, are an American racial and ethnic group who, as defined by the United States census, consists of Americans who have ancestry from "any of the Black racial groups of Africa". African Americans constitute the second largest racial and ethnic group in the U.S. after White Americans. The term "African American" generally denotes descendants of Africans enslaved in the United States. According to annual estimates from the U.S. Census Bureau, as of July 1, 2024, the Black population was estimated at 42,951,595, representing approximately 12.63% of the total U.S. population.

African-American history began in the 16th century, when African slave traders sold African artisans, farmers, and warriors to European slave traders, who transported them across the Atlantic to the Western Hemisphere. They were sold as slaves to European colonists and put to work on plantations, particularly in the southern colonies. A few were able to achieve freedom through manumission or escape, and founded independent communities before and during the American Revolution. After the United States was founded in 1783, most Black people continued to be enslaved, primarily concentrated in the American South, with four million enslaved people only liberated with the Civil War in 1865.

The Indian Ocean slave trade, sometimes known as the East African slave trade, involved the capture and transportation of predominately sub-Saharan African slaves along the coasts, such as the Swahili Coast and the Horn of Africa, and through the Indian Ocean. Affected areas included East Africa, Southern Arabia, the west coast of India, Indian ocean islands (including Madagascar) and southeast Asia including Java.

The source of slaves was primarily in sub-Saharan Africa, but also included North Africa and the Middle East, Indian Ocean islands, as well as South Asia. While the slave trade in the Indian Ocean started 4,000 years ago, it expanded significantly in late antiquity (1st century CE) with the rise of Byzantine and Sassanid trading enterprises. Muslim slave trading started in the 7th century, with the volume of trade fluctuating with the rise and fall of local powers. Beginning in the 16th century, slaves were traded to the Americas, including Caribbean colonies, as Northern, Western, and Southern European powers became involved in the slave trade. Trade declined with the abolition of slavery in the 19th century.
