+The Fourth Crusade (1202-1204) was a [Crusade](/wiki/Crusade) by Western European armies, originally aimed at the Holy Land. Diverting from its course, crusaders instead besieged and sacked [Constantinople](/wiki/Constantinople), the Byzantine Empire's capital, in 1204. This act gravely weakened Byzantium and established the Latin Empire.
