By the time the Ottoman Empire rose to power in the 14th and 15th centuries, there had been Jewish communities established throughout the region. The Ottoman Empire lasted from the early 14th century until the end of World War I and covered parts of Southeastern Europe, Anatolia, and much of the Middle East. The experience of Jews in the Ottoman Empire is particularly significant because the region "provided a principal place of refuge for Jews driven out of western Europe by massacres and persecution".
