Question

How did the Crusades weaken the Byzantines

Answer 1

Answer:

The Crusades, which were first created for the objective of not only recapturing Jerusalem for Christianity, but also to protect the failing Byzantine Empire, weakened the Byzantium empire considerably. They were hailed as saviors of Christianity and was given open doors, but they instead looted the already poor Byzantium Empire of whatever treasures they owned. They also destroyed parts of the wall and significantly reduced the population through murderings in the streets.
