The case of Marino Faliero
Marino Faliero was the only sitting Doge ever beheaded for treason. He was also the only Doge who unquestionably plotted to murder his peers and declare himself Prince.
He had been elected to the highest office for life. He was rich. His family sprang from 6th c. Maritime Tribunes. He was a triumphant general, admiral, and diplomat. He was 76 when elected Doge. Why would he do what he did?
Two schools of thought prevail, based on the scanty evidence of hearsay, rumor, lost testimony, and chronicles with points of view to advance or axes to grind.
Both views may be true, or neither, entirely. Neither fully explains why a man of Faliero’s position and stature would plot to murder a thousand nobles and climb to his throne over their bodies.
14th century Venetian law examined crimes as to their intent. “Crimes of reason” were considered far more dangerous as they implied criminal intent. Crimes of passion pushed a person beyond rationality into madness, a state beyond legal responsibility for one’s actions, and were tried and sentenced differently.
Unless the criminal was doge.
Version 1
A CRIME OF REASON
“In Marino Faliero we have a fine figure of a Venetian noble in the Middle Ages—active, capable, respected, enjoying a great position and displaying striking ability.” (Horatio Brown)
He was also short-tempered and irascible. When he was made Governor of Treviso, he was said to have smacked the Bishop to the ground for being late to Mass. He was also said to nurture a deep resentment of the new aristocracy who seized control of the Republic, closed the Great Council, and created a nobility defined by membership in the Great Council.
Doge Faliero, for all his accomplishments, honors, and wealth, was consumed with contempt for the nobles who had made the republic their own private club. His last and greatest wish was to extinguish them forever, come what may. For him, the only way to save Venice from itself was to amputate the gangrenous limbs.
