2.

1. The Fourth Crusade, which took place from 1202 to 1204, was originally intended to recapture Jerusalem from Muslim control, but ended up targeting and sacking the Christian city of Constantinople (now modern-day Istanbul).

2. The Fourth Crusade is highly controversial and is often criticized for deviating from its original purpose, leading to the eventual weakened Byzantine Empire and the permanent division between the Eastern Orthodox Church and the Roman Catholic Church.
