-What were the 3 main causes of the Crusades?
1. Christians wanted the Holy Land because it was a massive trading route
2. Christians wanted the Holy Land for access to Jerusalem, the holy city of Christianity
3. Christians wanted to stem the expansion of Islam, which was expanding in the Middle East and threatening Christian holdings there.
Pope Urban II started the Crusades in the Council of Clermont in 1095.
Peter the hermit was the advocate for the Crusades, and led many people to believe that the Crusades were neccessary. He also gave speeches that roused the crusaders into having a stunning victory against the Muslim Army in the Siege of Antioch.
Saladin was the leader of the Muslim Army, and fought against the Christians in numerous holy wars.
1. Trade routes linked the Middle East to Europe
2. Many new technology as well as products were brought form the Middle East, including dates, palm, etc.
3. Establishment of Muslim religion inside the area, as seen even today.
hope this helps
