OK, so if King Baldwin IV of Jerusalem ahd not been a leper and consigned to an early death, what would the historic implications have been. I think that Baldwin IV was the best king the Kingdom of Jerusalem ever had and would have been able to stabilize and perhaps preserve the Kingdom. The Fourth Crusade grew out of the desire to prevent and later reverse the post-Baldwin IV loss of Jerusalem. With Baldwin IV surviving, and the Kingdom retaining Jerusalem, the Fourth Crusade could have been dealyed or never have happened. In that case, I think that the Doge of Venice would probably have died by then and not been able to subvert the Fourth into seizing Constantinople, since most of the Crusaders on the Fourth were signing up to go to Egypt. Anywho, without the loss of Constantinople in 1204, maybe the Byzantines would have been in a better spot to resist the Turks.
Any thoughts on longer-term consequences?
