The conspiracy of Bocconi was confined to malcontents of the rank of citizens; but one of a more dangerous nature, and which originated among the nobles themselves, was formed in the year 1309. This combination was made up of some of the most distinguished of those who were not of the Grand Council when the reform took place, and who had not been admitted afterwards, according to their expectations; and of some others of very ancient families, who could not bear to see so many citizens raised to a level with themselves, and who, besides, were piqued at what they called the Pride of Gradonico. These men chose for their leader, the son of James Theipolo, who had been proclaimed Doge by the populace. Their object was, to dispossess Gradonico, and restore the ancient constitution; they were soon joined by a great many of inferior rank, within the city, and they engaged considerable numbers of their friends and dependents from Padua, and the adjacent country, to come to Venice, and assist them, at the time appointed for the insurrection. Considering the numbers that were privy to this undertaking, it is astonishing that it was not discovered till the night preceding that on which it was to have taken place. The uncommon concourse of strangers created the first suspicion, which was confirmed by the confession of some who were acquainted with the design. The Doge immediately summoned the council, and sent expresses to the governors of the neighbouring towns and forts, with orders for them to hasten with their forces to Venice. The conspirators were not disconcerted; they assembled, and attacked the Doge and his friends, who were collected in a body around the palace. The Place of St. Mark was the scene of this tumultuous battle, which lasted many hours, but was attended with more noise and terror among the inhabitants, than bloodshed to the combatants. Some of the military governors arriving with troops, the contest ended in the rout of the conspirators. A few nobles had been killed in the engagement; a greater number were executed by order of the senate. Theipolo, who had fled, was declared infamous, and an enemy to his country; his goods and fortune were confiscated, and his house razed to the ground. After these executions, it was thought expedient, to receive into the Grand Council, several of the most distinguished families of citizens.
