How did Pompey restore the powers of the Roman tribunes?

Pompey the Great restored the powers of the Roman tribunes during his joint consulship with Marcus Licinius Crassus in 70 BCE.12

Following the rise of Lucius Sulla, the political influence of the tribunes had been significantly curtailed, as Sulla sought to stabilize the Senate's authority by removing alternative centers of power. During their year in office, Pompey and Crassus repealed the political aspects of the Sullan settlement, which included the full restoration of the tribunes' powers.312

This restoration was a significant political move that dismantled the solid legal framework Sulla had attempted to establish for the Republic. By returning these powers, Pompey helped create a political environment where demagogues—whether tribunes or consuls—could once again utilize the legal machinery of the popular assembly to pursue their ambitions. The restoration of the tribunician initiative subsequently benefited Pompey himself, as it allowed his supporters, such as the tribune Aulus Gabinius, to secure him extraordinary commands to address crises like the pirate threat and the war against Mithradates.24
