This is the reason why historians really do consider them perhaps the first true international bank. In other videos we talk about how in 1187, Salah al-Din is able to retake Jerusalem, but then in the Sixth Crusade and the Barons' Crusades, it goes back to Christian hands. But then 1244, it's retaken again by the Muslims and it stays under Muslim control all the way until the end of World War I. And so with Jerusalem taken in 1244, the whole goal of the Knights Templar, the whole purpose of their existence, starts to become less important. Although at this point, they are a significant and influential financial institution. As we go to the end of the 13th century, the whole crusader mentality starts to lose steam. You have the Eighth and Ninth Crusades, but they aren't successful.
