Have Jews ever enslaved other people of different heritage or beliefs?

Answer 1

Yes, but not for that reason.

The Ancient Israelites had slaves and are believed to have treated them similarly to how it was described in The Bible. Slavery was quite common in the Ancient World and most slaves were acquired as prisoners of war, not for religious reasons. The Israelite treatment of slaves was quite moderate given what the norm of slave treatment was.

Wealthy Jews were occasionally be slaveholders in Islamic States such as the Caliphates (where many Muslims were also slaveholders) and we also part of the slave trade. Jews were also occasionally slaveholders in the Americas where slavery was accepted. A number of Jews held African-American Slaves on their plantations in the United States and elsewhere. Jews did not enslave Africans because of their belief system, but because they and society around them bought into the idea that unpaid labor was acceptable.
