The office of Procurator of Saint Mark was one of the few lifetime appointments in the government of the Venetian Republic and was considered second only to that of the doge in prestige. It was routinely occupied by nobles belonging to the most influential families and typically represented the climax of a distinguished political career, although it was often an intermediate position prior to election as doge.

The Venetian patriciate 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., together with the feminine variant N.D.. 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.
