Doge of Venice; died 1205. He became doge in 1192, and in 1201 when nearly a centenarian he assisted in organizing the Fourth Crusade, became a crusader, took part in the capture of Constantinople, and was offered the imperial crown which he refused. Venice owed the establishment of her power in the Orient to his skill and energy. He died after an expedition against the Bulgarians (1205) and was buried in Saint Sophia.
