Pope Urban II wants reclaim Jerusalem from the Muslims. He convinced people to join by telling them fighting will forgive you from your sins. I chose this because it is important to know why people joined the Crusades
The first crusade was led by European nobles with around 100,000 crusaders. The crusaders surrounded Jerusalem and after about a month of fighting, Jerusalem fell to the Crusaders. I chose this event because this marked a beginning to a bloody war.
TThe Crusades weakened Feudalism and brought cultural diffusion & introduced new ideas into Western Europe. Learning increased & more people were educated. I chose this event because it introduces new products and technology into growing urban culture.
