The Seljuk Turks were going to Constantinople to take it over but the Emperor of the Byzantine Empire asked the Pope for help and he called a Crusade to take back Jerusalem.
The Crusaders were heading to Jerusalem to take it back from the Seljuk Turks.
The Muslims had conquered Edessa, which makes the Pope call for a Crusade. Since the Pope called for the Crusade, Saladin and the Muslims had recaptured Jerusalem.
How Western Europeans lives were changed from the Crusades
Richard l had attacked Jerusalem but he and Saladin didn't want to die so they signed a peace treaty.
I don't want to die -------------- Lets sign a peace treaty
Me neither ----------------- Ok
During this Crusade, the crusaders had destroyed Christian icons and stole relics. Bad call Pope!
( Couldn't find pictures of this stuff ) The Crusades had affected Western Europe in many ways. They had gained new knowledge, learned about spices, sugar, silk, lemons, a lot of architecture, more accurate maps, the use of a compass, and it had gotten rid of feudalism.
