Because when the Sunni Muslims and shia muslims split, the two groups could become dependent
a fight between the Christians and the Muslims over Jerusalem (their holy land).
The Crusades were a series of Holy Wars between Christians and Muslims over 'the Holy Land' in medieval Europe.
The Crusades were holy wars fought between Christians in Europe and Muslims in the Middle East between 1095 and 1291.
I presume you mean The Crusades. The Crusades were Holy Wars in the 11th to 13th centuries waged by Christians from western Europe to regain the holy city of Jerusalem from the Muslims. The First Crusade succeded, but Jerusalem was subsequently regained by the Muslims, and the later Crusades failed to regain it.
Australia and eastern europe fought together to defeat the muslims who kept the christians from seeing the birthplace and crusifiztion place of jesus
they stopped the Europe from being taken over by Muslims and they allowed Christians to be able to safely go to the holy land.
The crusades began in Europe. Pope Urban the 2nd called it, because the Muslims had banned the Christians for entering or visiting Jerusalem the holy land. The Crusades were a series of wars, but the first 4 were called my the church. The rest of them weren't.
The Christians of Europe led the Crusades, and sometimes their holy rulers or kings would lead them in battle. An example of this would be Pope Urban II on the first crusade. They were waged against the Muslims, Russian and Greek Orthodox Christians, Mongols, Cathars, Hussites.
Because of the Crusades there is to this day tension between Christians, Jews, and Muslims; especially in the Middle East. Another effects: formidable costs, crimes, destruction, murders, robberies, hate, wars. Crusades were criminal actions of the damned catholics from the Western Europe.
The Crusades
Well, the Christians in europe believed that palestine was the Holy Lands* and wanted to regain them from the Muslims. *Holy Lands=Place where Jesus supposedly lived, died, and preached.
We may presume that the first encounter of the Europeans with the damascus steel was during the crusades where christians and Muslims faught for the control of the Holy Land.
