The patricians (from Latin: patricius) were originally a group of ruling class families in ancient Rome. The distinction was highly significant in the Roman Kingdom, and the early Republic, but its relevance waned after the Conflict of the Orders (494 BC to 287 BC). By the time of the late Republic and Empire, membership in the patriciate was of only nominal significance.

The social structure of Ancient Rome revolved around the distinction between the patricians and the plebeians. The status of patricians gave them more political power than the plebeians. The relationship between the patricians and the plebeians eventually caused the Conflict of the Orders. This time period resulted in changing the social structure of Ancient Rome.
