Slavery has excisted allways, but for our time there are three main slave trade routes/dealers, and first one was also last.
First, and also "last", was trans Sahara slave trade where black africans sold captured black africans to arab slave traders, who then transported them all around muslim/arab world as slaves. Arab slave trade has been also oldest and longest and official end of it was 1960's.
Second big route was west african pirate route where slaves were captured once again from africa, but also all over european. White european were captured by millions and it was also actual reason to european white kingdoms go apeshit against african pirate fleet.
When african pirates were defeated and made agreement third route was trans Atlantic slave trade, where again african negroes captured other african negroes to arab slave traders who sold them white (jew) slave traders etc etc etc.
From all those three examples white slave trade was first and only to actually end slave trade and free'd all slaves: around 1860 Great Britain took loan, about 40% nations budget, and literally paid for every slave owner in west for every slave to be set free. This loan was paid back in full 2015, which mean literally present day brits paid to end slavery and set them free.
Arab slave trade has been longest and biggest in world history, but for some reason no one is blaming arab muslims about slavery, no guilt trip, no reparations, nothing.
