This is a map of the region as we enter into the 14th century, and you can see that the Muslims have retaken not just the Holy Land, but most of the Anatolian Peninsula, with only Constantinople being in control of the Byzantines, and that lasts until 1453, when the Turks finally take Constantinople as well. When you look at the map at the beginning of this video and look at the map here, you can see that the crusades weren't really successful at changing the picture in the Holy Land. There were areas where the crusades were successful, or that crusader mentality was successful. You can see that now that we're in the 14th century, much of the Iberian Peninsula has been taken by Christian kingdoms from the Muslims. The Muslims at this period are left with only Granada. So the Reconquista, to some degree, was successful, and it's going to continue until 1492, when the last Muslims are expelled from Spain. Now, one thing that I felt when I studied the crusades is it's very confusing how Jerusalem in particular goes back and forth between different parties.
