The Byzantine emperor, a Christian monarch who lived in Constantinople, needed help.
He turned to the pope, who in 1095 called for all Christians to start a holy war against the
Suljuk Turks. Thousands rushed to join the Crusader armies. They crossed into Palentine
and recaptured the important cities of Nicaea and Antioch. Jerusalem fell in 1099 after a
desperate siege lasting six weeks, and the Crusaders took terrible revenge by slaughtering
thousands of Muslims. There were to be three more crusades: one in 1144, the second
in 1187 and finally the Children’s Crusade in 1212. Fifty thousand children set off from
France and Germany for the Holy Land. Many died on the journey, many more were
captured and sold as slaves in Africa.
