Barbar pirates that took american and european soldiers and enslaved them, no?

Also ....there were Asian slaves... no? Tibet before 1949 was pretty much a state ran by aristocratic monks who turned the poorest Tibetans into their own personal slaves.

Back them it was mostly Asians who enslaved other Asians in Asia. Even nowadays Indians, Rohingya, Sri Lankan, and Bengali people are routinely lured in with the promise of easy , high-paying work in the Gulf states then trapped as slaves in pretyy much all the gulf states other than Yemen. I think that abour half the population of some Gulf states are just trapped workers. Theres also still back-alley debt slavery in India too today.
