That’s great!
The West greatly damaged and ravaged the Empire with the fourth crusade- it has been said it was the greatest ravaging
of a city in history. The booty carried off adorns many Catholic churches and places today. You may have heard about http://en.wikipedia.org/wiki/Horses_of_St_Mark these famous horse statues...they were stolen from Constantinople. The West, and I mean the Church and the countries wouldn’t come to the help of the eastern Empire, and almost paid the price with the Battle of Vienna. If they had lost that Europe would be Muslim now, as we all probably would be as well.
