The Huge slave trade of Eastern European people in the Ottoman Empire, Muslim Spain and Middle East by Jews and Muslims. http://evoandproud.blogspot.com/2013/07/the-other-slave-trade.html The numbers were huge. At the height of that trade, over 10,000 Eastern Europeans were enslaved each year between 1500 and 1650 for export to North Africa, the Middle East, and Ottoman Empire … a total of 1.5 million. By comparison, the Americas received fewer than 300,000 African slaves before 1600 and another 1.5 million between 1600 and 1700 (Fisher, 1972; Kolodziejczyk, 2006). Western Europeans were likewise enslaved and taken abroad, mainly to North Africa. How many? More than 1 million between 1530 and 1780 (Davis, 2004).

The first is cohabitation of Jewish men with female slaves, usually non-Jewish, who in effect served as their concubines and bore them legitimate children; the second is marriage with manumitted slaves who converted to Judaism and became an integral part of the community.
