1095 CE: CRUSADES commence

–with widespread killings of Jews as a backdrop.

Nine Crusades would be launched (between 1095–1272 CE) into the Middle East, with Jerusalem, and Christian control thereof, as the penultimate target.

The Ninth Crusade, the last major medieval Crusade, ended with the fall to the (Arab) Mamluks of Tripoli [now Libra] (1289) and Acre [Holy Land] (1291). Those Christians unable to leave the cities were massacred and the last traces of local Christian rule in the Levant disappeared.
