In Ancient Rome, the social order of the patricians was composed of the descendants of the thirty primitive curias. The name comes from pater (father), in reference to the founders, that is, to the first parents of Rome. He is the senator par excellence and is part of the primitive nobility of Rome, called nobility of blood and ilustrii or nobilitas patritii, and cultural substrate of all Europe.
