about increased authority for the plebeian assembly and its leaders, and it was greatly due to concessions made by dictators and consuls that the now mobilized and angry plebeian population began to develop power. In 339 BC, the Lex Publilia made plebiscites (plebeian legislation) law, however this was not widely accepted by patricians until the 287 BC Lex Hortensia, which definitively gave the council the power to create laws to which both plebeians and patricians would be subject. Additionally, between 291 and 219 BC, the Lex Maenia required the senate to approve any bill put forward by the Plebeian Council. In 88 BC, Sulla introduced measures which transferred all voting power to the Comitia Centuriata from tribal assemblies, therefore rendering the Council of the Plebs virtually powerless. After 27 BC Although the Plebeian Council survived the fall of the Roman Republic, it quickly lost its legislative, judicial and electoral powers to the Senate. By virtue of their status as perpetual tribunes, both Julius Caesar and the Emperor Augustus always had absolute control over the Plebeian Council. The Plebeian Council disappeared shortly after the reign of Tiberius. The Plebeian Council and the Conflict of the Orders The creation of the office of plebeian tribune and plebeian aedile marked the end of the first phase of the struggle between the plebeians and the patricians (the Conflict of the Orders). The next major development in this conflict occurred through the Plebeian Council. During a modification of the original Valerian law in 449 BC, plebiscites acquired the full force of law, and thus applied to all Romans. Before this time, plebiscites had applied only to plebeians. By the early 4th century BC, the plebeians, who still lacked any real political power, had become exhausted and bitter. In 339 BC they facilitated the passage of a law (the lex Publilia), which brought the Conflict of the Orders closer to a conclusion. Before this time, a bill passed by any assembly could become law only after the patrician senators gave their approval, which came in the form of a decree called the auctoritas patrum ("authority of the fathers" or "authority of the patrician senators"). The lex Publilia required the auctoritas patrum to be passed before a law could be voted on by one of the assemblies, rather than afterward. This modification seems to have made the auctoritas patrum irrelevant. Thus, the Plebeian Council became independent of
