Answer :
Final answer:
The consequence of Roman expansion in 300 BCE led to social, economic, and political challenges within the Republic, altering the military system and governance structure.
Explanation:
One consequence of Roman expansion beginning in 300 BCE was that the republic faced social, economic, and political problems. Rome's continuous wars and conquests led to dissatisfaction among the Roman people towards the Senate and elite leaders, shifting their trust towards strong military figures.
As a result of expansion and conflicts, the military system declined, transitioning to a professional army loyal to specific generals, rather than citizen-soldiers.
Furthermore, the Roman Republic had to adapt to ruling a vast empire, leading to the division of conquered territories into provinces with senatorial governors, changing the dynamics of governance.
