In 1095, conflict between Christians and Muslims sparked a crusade (a military campaign in defense of Christianity) for the Battle of Jerusalem. This crusade involved people of religions other than Christianity, such as the Jews, but they did not play a major role at this time. The Crusades lasted almost two decades and consisted of eight different crusades. With all the events and actions that took place during the Crusades, it has had too many effects over the years. The Crusades had short- and long-term effects that affected people of all cultures. Two countries that had many effects from the Crusades were Europe and Islam. The Crusades had short- and long-term effects on power, economics, and classical knowledge throughout Europe and Islam. For the Crusades to begin, Christians needed to gather an army to travel and fight Muslim forces. With all the power held by monarchies at this time, the Church needed to be sharper in order to recruit troops willing to risk their lives. To gain the support of these warriors and the devotion of the men, Pope Urban II (1088-1099) challenged the morals of the men by telling them to take up their weapons and join in the holy war to reclaim the land of Jerusalem. It was not the challenge that convinced men to take part in this war. The promise of “immediate remission of sins” inspired men to defend their religion and beliefs while promising them a trip to paradise at the end of their lives. With this declaration, men immediately prepared for the fight which, in a very short time, gave the Church the power held by the monarchies. Rich and poor men prepared for battle, some wearing ...... middle of paper ...... Some of these effects still take place today. Works Cited Spielvogel, Jackson J.
