Libro d'Oro della Nobiltà italiana (official register) in the context of "Venetian nobility"

The Venetian patriciate (Italian: Patriziato veneziano, Venetian: Patrisiato venesian) was one of the three social bodies into which the society of the Republic of Venice was divided, together with citizens and foreigners. Patrizio was the noble title of the members of the aristocracy ruling the city of Venice and the Republic. The title was abbreviated, in front of the name, by the initials N.H. (Nobilis Homo or Nobiluomo), together with the feminine variant N.D. (Nobilis Domina). Holding the title of a Venetian patrician was a great honour and many European kings and princes, as well as foreign noble families, are known to have asked for and obtained the prestigious title.

The patrician houses, formally recorded in the Golden Book, were primarily divided into Old Houses (Case vecchie) and New Houses (Case nuove), with the former being noted for traditionally electing the first Doge in 697 AD. The New Houses were no less significant, as many became very prominent and important in the history of the Republic of Venice. The families were furthermore divided into several other "categories", including Ducal Houses (Case ducali, whose members had become Doges), Newest Houses (Case nuovissime) raised to the patriciate in 1381, non-Venetian patrician families, and "Houses made for money" (Case fatte per soldo, usually wealthy landowning or bourgeoisie families who contributed to the state during the War of Candia and the Morean War).

The Great Council or Major Council (Italian: Maggior Consiglio; Venetian: Mazor Consegio) was a political organ of the Republic of Venice between 1172 and 1797. It was the chief political assembly, responsible for electing many of the other political offices and the senior councils that ran the Republic, passing laws, and exercising judicial oversight. Following the lockout (Serrata) of 1297, its membership was established on hereditary right, exclusive to the patrician families enrolled in the Golden Book of the Venetian nobility.

The Great Council was unique at the time in its usage of lottery to select nominators for proposal of candidates, who were thereafter voted upon.
