In 1310 the Doge of Venice, Pietro Gradenigo, representating the “new aristocracy” against the “old houses,” was becoming increasingly hated by the people. His war of aggression against Ferrara resulted in the Pope (with his own interests in Ferrara) excommunicating the entire state of Venice.
The Pope followed up the excommunication by granting liberty and indulgence to anyone who attacked Venetian
subjects or property. Throughout Europe, Venetian merchants were sacked; counting houses, banks, and factories were looted and destroyed.
With a Doge besieged by failure and popular discontent, the opposition party, the “old houses,” lacked
only one thing: a popular leader.
Enter Bajamonte Tiepolo.
The conspirators met at Marco Querini’s palace. Querini hammered away at the injustice of the Closing of the Great Council, which excluded noble and common citizen alike from participating in the government of the Republic.
Bajamonte replied:
The conspirators laid plans to converge on St. Mark’s
Square, assault the Doge’s Palace, and assassinate the Doge on June 15, 1310.
They didn’t know that the Doge had learned of their plans and massed his troops to defend the palace from assault.
The conspirators were divided into three groups. One group, under Bajamonte, marched across Rialto Bridge to St. Mark’s Square. The second group, under Marco Querini, took an alternate route to the Square. The third group, under Badoer Badoer had massed recruits on the mainland and planned to transport them by boat to St. Mark’s Square.
Querini’s contingent, not knowing about Bajamonte’s delay, reached the Square first. They were met by the Doge’s troops. Querini and his two sons were killed straight off, before Bajamonte reached the Square.
Bajamonte arrived at St. Mark’s during the rout of Querini’s men; his standard-bearer was slain by a mortar flung from a balcony. His banner proclaiming “Liberty” was trampled in the mud. Bajamonte’s men panicked and raced back toward Rialto, crossed the bridge and burned it behind them.
The fate of the missing third contingent eventually reached Bajamonte. The storm drove their boats aground and the governor of nearby Chioggia, dispatched by the Doge, captured them all.
Too popular to be summarily executed, Bajamonte Tiepolo was banished in perpetuity and disappears from the stage of history, like his home, which was razed to the ground and the ground beneath it sowed with salt.
THE COUNCIL OF TEN IS CREATED.
The most significant outcome of the Tiepolo Conspiracy was the creation of the Council of Ten, first constituted for a term of days to investigate and prosecute the conspirators. The term was renewed for two months, then for five years, and, on July 20, 1355 the Council of Ten became permanent, creating the most powerful and secretive committee in the Republic.
