Who was the Roman general to march his army into the city of Rome? Explain the future effect of this decision.

The Roman general who marched his army into the city of Rome was Julius Caesar. He did this in 49 BC, during a civil war against his rival Pompey.

The future effect of Caesar's decision to march his army into Rome was significant. This act marked the end of the Roman Republic and the beginning of the Roman Empire. Caesar was declared dictator for life and implemented many political and social reforms that transformed Roman society. His influence was so great that the month of July was named after him (Julius) and his adopted son and successor, Octavian, would later become the first Roman Emperor, taking the name Augustus.

The Roman general who marched his army into the city of Rome was Lucius Cornelius Sulla, also known as Sulla. He did this in 88 BCE as part of a power struggle during the late Roman Republic.

The future effect of Sulla's decision to march his army into Rome was significant. It marked a turning point in Roman history and had several key effects:

1. Consolidation of Power: Sulla's actions allowed him to consolidate his power and establish himself as a dictator in Rome. He used his position to enact a series of reforms and reforms brought stability to Rome's political and social systems.

2. Violence and Political Purge: Sulla's march into Rome initiated a period of violence known as the Sullan proscriptions. He ordered the execution of his political enemies and confiscated their property, which resulted in a significant loss of life and a climate of fear in Rome.

3. Weakening of the Roman Republic: Sulla's actions further weakened the already fragile Roman Republic. By disregarding the traditional limitations on the military's involvement in politics, he set a precedent for future generals to seize power through force, undermining the democratic system.

4. Precedent of Military Intervention: Sulla's march into Rome set a dangerous precedent for future Roman generals and politicians. The use of military force to seize power became a viable option, contributing to the decline of the republic and ultimately leading to the rise of Julius Caesar and the Roman Empire.

Overall, Sulla's decision to march his army into Rome had far-reaching consequences, including consolidating his own power, initiating a period of violence, weakening the republic, and establishing a precedent for military intervention in politics that would have lasting effects on Roman history.
