Patricians historically had more privileges and rights than plebeians. The prohibition on intermarriage between patricians and plebeians was thus repealed. The status of patricians gave them more political power than the plebeians. The distinction between patricians and plebeians in Ancient Rome was based purely on birth. Tarquinius was ousted by a conspiracy of patricians, not plebeians. This noble status is what separated the patricians from the plebeians. A new magistracy open to patricians and plebeians, the praetorship, was also created. Through this office, patricians were able to maintain their hierarchy over the plebeians. The relationship between the patricians and the plebeians eventually caused the Conflict of the Orders. However, an unusual agreement was ultimately secured between the Plebeians and the Patricians. This later changed, and both Plebeians and Patricians could stand for Curule Aedileship. The powers of a magistrate came from the people of Rome (both plebeians "and" patricians). It was an important reform shifting practical power from the patricians to the plebeians. Since the tribunes were considered to be the embodiment of the plebeians, they were sacrosanct. The mercatores were usually plebeians or freedmen.
