From 1260 to 1517, Jerusalem was ruled by the Mamluks. In the wider region and until around 1300, many clashes occurred between the Mamluks on one side, and the crusaders and the Mongols, on the other side. The area also suffered from many earthquakes and black plague. When Nachmanides visited in 1267 he found only two Jewish families, in a population of 2,000, 300 of whom were Christians, in the city. The well-known and far-traveled lexicographer Fairuzabadi (1329–1414) spent ten years in Jerusalem.
