The main goal of the Crusades was to restore Christianity in the locations in and around Jerusalem. However, it is equally as likely that the crusades also existed as a military campaign (this is well-know) with lesser well-known reasons such as economic and political reasons. The crusades were taken up by some Christians across Western Europe, as the pope had announced it as the right thing to do and that all sins were forgiven if people were to go on the Crusades. Many of these battles were unsuccessful.
