It is hard to say when slavery began, it has been a form of civilization for a long time until it was made illegal in England, which was a massive empire at the time, in 1772. But slavery had begun in many ancient civilisations, including the Romans and Ancient Egyptians. Yet even now slavery hasn't ended, there are many slave trades still in place including child trafficking and the sex trade, all in many opinions as a slave trade. I cannot provide any proper dates especially as I cannot say when these modern slavery forms will end.
they allowed slavery because it was cheap
The ancient Greece civilization had many characteristics but the most important one is bravery. It fought so many wars and also won so many. This is a true trait. :)

Slavery had existed in many modern and ancient civilizations. For the most part, the US Civil War had ended the institution of slavery in all developed nations. Any society that tolerates the existence of slavery is at once a society that has serious flaws. Where slavery has existed, the slaves in a society had few civil rights if any at all. Any civilization which tolerates slavery is not one that can be called "democratic" in the broad sense of that term.
they went into slavery for it

Ancient China made many contributions to civilization. The study of math, fishing reels, mechanical clocks and many other things were discovered or invented by people in ancient China.
