Enrico Dandolo

Enrico Dandolo (c. 1107 – May 1205) was the 42nd Doge of Venice from 1192 until his death.

When the Fourth Crusade began, the crusaders needed transport aboard Venice's ships. Dandolo agreed, on the condition that they take the n city of and capture Constantinople.

As the crusaders took Constantinople, the Venetian fleet sacked it, stealing four bronze horses, among other things. The horses were later used as ornaments on St Mark's Basilica.
