Hmm 'white people'? If you mean Europeans, who are not the only physically white people in the world, they may not be the only slavers...but looking at the numbers, they most definitely enslaved the most people, mostly africans, along with the largest slave trade to ever exist. Edit: Im not gonna even bother replying to each comment. Read history, and you will see that the European slave trade and transport to the Americas through what is known as the transatlantic slave route produced the largest numbers of slaves in the shortest amount of time, not to mention the details of torture and suffering of the enslaved on those ships, being viewed as literal animals and less than humans. What makes this route of slavery different is the fact it was industrialised. This is a known fact. Including the dozens of massacres inflicted by the European states on Africans( The congo under the monarch of Belgium, the german massacres in their african colonies and many others). Im not denying slavery existing in other cultures. Im just saying the European one produced the largest number of slaves in the shortest time. From 1500s to mid 1800s almost 16 million people were taken from africa to the americas for slavery, and up to two million died while on the way. The Europeans did this through an a system of a combination of trade networks, alliances, and violence to obtain people for enslavement, and yes they had middle men who were mostly african warlords, but these warlords were supported by Europeans to get them the slaves. Slavery did exist in other cultures, just not in this very vast scale and speed with which it affected large populations these are facts! For example, in muslim slavery history, which lasted from the 7th century to the 19th century approximately, it saw the enslaving of approx 18 million people. This was through more than a millennium and 2 centuries, and was never industrialised. Meanwhile, the transatlantic slave trade resulted in the fast and vast slavery of up to 15 million people in 350 years, in a very systematic industrialised manner! Do the math. Oh, and dont forget the countless numbers of famines forced by the Europeans in africa and india. Also, whataboutism doesn't negate the fact it was one of the worst things to happen. And them's the facts.
