Yesterday, the history channel had a special representation on the Crusades and one special emperor was Alexius. Alexius, with the Byzantine Empire dwindling, made or more begged Pope Urban II for aid. Turns out, Alexius was only asking for 500 of the Western's best knights, but rather he got 60,000 total Crusaders at the gates of Constantinople that could storm his city and take it over easily. So how would Alexius solve this problem. Luckily Alexius was in control of food shipments and so blackmailed the Crusade's leaders into loyol obedience with him. He ordered them to reconquer Byzantine land taken by the Turks and so the Crusaders did. Sure Alexius was smart, but what he forgot was when the Crusaders conquered the cities, how would he control them when they had their own resources from the cities conquered. It was a good move, but in the long term a really bad one. I also want to note that Crusades was so full of political dealings and much betrayals and extreme massacres.. Everything was done for wealth and more land and religious zealot was only a false forefront.
