Marino Zorzi, born in Venice around the year 1231, served as the fiftieth Doge of the Republic of Venice from August twenty-third, 1311, until his passing on July third, 1312. His election came at a tumultuous time, as the city faced unrest due to the attempted revolt of Bajamonte Tiepolo and ongoing tensions with Rome, which was still resentful over Venice's occupation of Ferrara.
Despite not being the initial choice for the position, Zorzi took on the role of Doge after Stefano Giustinian declined the honor. His tenure, however, was brief and marked by challenges, including several natural disasters that plagued the city. Zorzi's efforts to mend relations with the Papacy were largely unsuccessful, and his reign lasted a mere eleven months.
Known for his devout nature, Zorzi was respected during his lifetime and was even considered a saint. His garments became sought-after relics after his death, reflecting the reverence in which he was held. His dogaressa, Agnese, played a significant role in the silk industry, ensuring that the silk-masters of Lucca trained apprentices and oversaw the production of silk fabrics in Venice.
