But regardless of the actual facts here, as we go into the first quarter of the 13th century, Jerusalem remains in the hands of the Muslims. A fifth crusade is launched to retake Jerusalem, which is a failure. Eventually, a sixth crusade is launched, and this is reasonably successful at retaking some land in the Holy Land, but shortly thereafter, you have a non-numbered crusade, the Barons' Crusade, that rivals the first crusade in its success in taking territory. And so you can see, after the Barons' Crusade right over here, they're able to take back a good amount of territory. But then in 1244, Jerusalem is retaken by the Muslims, and then you have the Seventh and Eighth and Ninth Crusades afterwards, and you have these other efforts that are sometimes called crusades, but for the most part, these are unsuccessful. And as we get into the end of the 13th and early 14th centuries, the Holy Land falls back under Muslim control. 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.
