In addition to the expert answer by Cassandra it should be noted that human trafficking - which is just slavery under another name - is still a major problem in the world.
While there are still many Africans who fall into modern slavery, the significant majority of victims now are now from Eastern Europe, the Middle-East, South & Central America, China, India, Pakistan, Bangladesh, and Southeast Asia.
Slavery did not begin with the African people; it started long before. Slavery dates back to pre-Biblical times. Warring tribes took slaves as part of the "spoils of war". Egyptian Pharaohs had slaves build the pyramids.
ALSO, and importantly, people (black, white, brown) choose to let others take their children as slaves if the parents had no way to feed their child/ren. When a passing ship stopped at islands, families would offer their kids as barter to receive food, tea, sugar, etc. for themselves AND so the child would be fed on the ship; however, once enslaved, children barely received nutrition.
NOTE: ALL people have very-long-ago ancestors who were slaves. The African slave story only differs in that it is still "recent" historically.
africans who had sold other africans to slave traders
I think they may have been brought over as slaves
no it is not , they pretended to sell there family to get them to freedom , and i totally dissagre, and im whiteAnother answer: Although some where captured by raiding parties from the ships most of the Africans shipped as slaves to America where bought from other African tribes. They had usually either been captured in battles or in raids on other tribes and were then traded to Europeans for goods. So, most of the Africans who became slaves were sold into slavery by other members of their own race.
the civil war was fought over the issue of slavery. most of them were already slaves. they wanted to stop what they had been through, so that other Africans would not suffer through it.
People have been enslaving each other for centuries. Mostly slaves came as spoils of war.
White people have been slaves, as have been black people, yellow people, and red people. Slaves have come in all types of colors, and both genders; male and female. People of all ages, young and old, have been slaves.
Yes, during the historical period when Europeans were going to Africa to obtain slaves, Africans did sell other AFricans into slavery. Generally speaking, the prevailing morality of the time was that only members of your own tribe or ethnic group are real people or have human rights; members of other tribes or ethnicities are the equivalent of wild animals, toward whom you have no moral obligations. They are just another resource to be exploited at will. Many people still feel that way. Just observe how the Hutus and Tutsis have been treating each other in recent years, for example.
Africans lived in villages since there have been Africans, basically, millions of years. Humans need to sleep in villages with other people to be protected from wild animals.
Africans captured their own people to make them slaves. Slavery has been going on since man kind. Slaves get beat to death in front of people to intimidate them. John Willberforce wrote the song Amzing grace many years later after he sold so many slaves. He wrote Amazing Grace after guilt because he sold 20,000 slaves and they all died and haunted him for selling them.
Slaves have been used throughout mankind's history. They historically come from people abducted by force, people given away or sold by their leaders, people who sell themselves or people conquered in war.African slaves were used in America and Europe, primarily because their tribal leaders and kings sold them to the slave traders. Many other races were sold into slavery at the same time, but not in the same numbers.Scholars estimate that about 12,000,000 Africans were sold by Africans to Europeans (most of them before 1776, when the USA wasn't yet born) and 17,000,000 were sold to Arabs.Slavery still exists in many countries today.You have asked "why". Because it was (and still is in some places) possible to buy people as servants and workers.
Many tribes fought each other, so they would capture people from the other tribe and sell them into slavery. This is not something new in history. In war people have been taken and sold into slavery for centuries. The Greeks used pirates to sell slaves around the ancient world and so did the Romans.
People have been making others their slaves since the beginning of humanity and still do.
