The Forth Crusade

My goodness, how long is this going to last!?!?! Pope Urban III gets ready for yet another crusade.  This crusade attracted no support from any European monarchs, so it was led by the French Knights.  Other than trying to go after the Holy Land, the leaders of this crusade were persuaded into going after the capital of the Byzantine Empire, which was already a Christian city.  The main accomplishment they made was to weaken the Byzantine Empire enough for the Muslims to keep expanding.  Well that was a pointless battle!
