How did Islam affect Byzantine empire?

Answer 1

The crusades, originally intended to save the Byzantine Empire, among other things, failed to do this and hastened its decline instead. The crusaders sacked Byzantine cities and eventually captured Constantinople in 1204. They then used Constantinople as the capital of what is called the Latin Empire, which it remained, until the Byzantines managed to recapture it in 1264. The Byzantine Empire never really recovered from this, though it held on for almost another 200 years.

In general terms, the Crusades affected the Byzantine Empire negatively. For one thing, the marches of the Crusader armies through Byzantine territory typically led to destruction and disorder, if but rarely on a grand scale. For another thing, the jealousies and ambitions of Western powers in respect to Byzantine wealth (along with religious differences) sometimes led to actual attacks by Crusader forces upon the Byzantines while en route to the Holy Land, with the most famous example of such an attack occurring in 1204.
