The Venetian government structure was similar in some ways to the republican system of ancient Rome, with an elected chief executive (the Doge), a senate-like assembly of nobles, and a mass of citizens with limited political power, who originally had the power to grant or withhold their approval of each newly elected Doge. Church and various private properties were tied to military service, although there was no knight tenure within the city itself. The Cavalieri di San Marco was the only order of chivalry ever instituted in Venice, and no citizen could accept or join a foreign order without the government's consent. Venice remained a republic throughout its independent period, and politics and the military were kept separate, except when on occasion the Doge personally headed the military. War was regarded as a continuation of commerce by other means (hence, the city's early production of large numbers of mercenaries for service elsewhere, and later its reliance on foreign mercenaries when the ruling class was preoccupied with commerce).
No, it's The Merchant of Venice . A play that will make you writhe in discomfort even while you laugh, snicker even while you get weepy, contemplate the evilness of men even while feeling kinda warm and fuzzy inside when they do the right thing, root on one of the fiercest heroines in all of drama... and, because this is Shakespeare, gawp in amazement at the language acrobatics, wit, and poetry of this dang masterful play.
