What does patricians do mean ancient Rome?

The patricians were the aristocracy of ancient Rome. The name is derived from the term pater familias (father of the family/head of the household) and from the creation of the senate by Romulus, Rome's founder and first king. Romulus created a council of elders (senate is derived from senex, the Latin for old man) to act as the royal advisory body. He selected 100 pater familias from the leading clans of Rome at the time to seat in the senate. The members of these clans then called themselves patres (plural of pater) a term which implied that they were the fathers of the city.
