The counts of Tusculum were the most powerful secular noblemen in Latium, near Rome, in the present-day Italy between the 10th and 12th centuries. Several popes and an antipope during the 11th century came from their ranks. They created and perfected the political formula of noble-papacy, wherein the Pope was arranged to be elected only from the ranks of the Roman nobles. Pornocracy, the period of influence by powerful female members of the family also influenced papal history.
