What role did the Roman Catholic Popes play in most of the Crusades? They traveled to Jerusalem with the Crusaders and helped plan most of the attacks on Jerusalem.

They discouraged Crusaders from killing more infidels than was necessary to take control of Jerusalem.

They ordered or approved the Crusades and told knights it was God's will to kill people who were not Christians.

They provided the money required to train knights and feed them on their long journeys.
