How did the increasing power of the military leaders help bring about the end of the republic

in Rome?

The increasing power of the military leaders in Rome helped bring about the end of the republic by allowing them to gain control of the government. As the military leaders gained more power, they began to challenge the authority of the Senate and the elected officials. This led to a series of civil wars, which weakened the republic and allowed the military leaders to take control. Eventually, Julius Caesar was able to seize power and declare himself dictator, ending the Roman Republic and ushering in the Roman Empire.
