We just learned about the Second Crusade.
Another part of the crusades was the Third Crusade.
After the Second Crusade, one of the Muslim rulers named Saladin took back Jerusalem in some other battles.
So the church and the European countries decided to go to war again.
They battled their way through Asia toward Jerusalem, and took over a lot of land but did not take back Jerusalem.
Even though they won most of their battles, people were still upset that they did not take back Jerusalem, and came back home.
