Remember, the Crusades were started by a Pope working people up, saying, hey, let's go help the Byzantines. Let's go take back land from the Muslims, Pope Urban II, and over the course of this 200 years, you have this religious fervor where the Pope is organizing these Crusades. People are feeling this religious spirit. Many people are, before going on their crusade, they're bequeathing their land to the church. If they die, and many of these lords do end up dying, they're giving their property to the church headed by the Pope. Kings also gained power during the Crusades. In other videos, we talk about the feudal system, and many times, the vassals to the kings, the dukes, the counts, the barons, often had more control over their territory than the kings might have had, and they were constantly squabbling with each other, but as people started to focus their energies on this external adventure known as the Crusades, first of all, many of these lords died.
