Fourth Crusade Route

Map showing the main route followed by the fourth crusade

This map shows the route taken by the Fourth Crusade which was preached by Innocent III in 1202. The majority of the Crusaders sailed from Venice. The goal was the recapture of Jerusalem through an invasion of Egypt, however, the Crusaders were persuaded to mount an attack on behalf of the Venetians at Zara and then on Constantinople to depose the Emperor. The fall and sack of Constantinople in April 1204 did lasting damage to relations between Eastern and Western Christians. A Latin empire lasted there for 60 years.
