The West responded with the Crusades, eventually resulting in the Fourth Crusade which conquered Constantinople in 1204. Several Roman states took pieces of the now smaller empire. After the recapture of Constantinople by the Romans, the empire was little more than a Greek-speaking state confined to the coast of the Aegean Sea and the Sea of Marmara. The empire came to an end when Mehmed II conquered Constantinople on 29 May 1453.
