Jacopo Tiepolo

Jacopo Tiepolo (c. 1170–1249) served as Doge of Venice from 1229 until his abdication in May 1249. He became the first Venetian Duke of Crete (1209–1214), enlisting Marco Sanudo to suppress the Greek revolt of 1211.

He was twice Podestà of Constantinople, signing treaties with Nicaea and the Sultanate of Rum. As doge he codified civil law and established the Venetian Senate.

From 1237 he fought Emperor Frederick II: his son Pietro was captured at Cortenuova and executed in 1240, when Venice also seized Ferrara. Tiepolo reconquered Pula in 1242, abdicated in 1249 and died two months later.
