3.2 The Roman Senate

The Roman Senate, a cornerstone of ancient Roman government, wielded immense influence over politics and policy. Composed of wealthy aristocrats, it controlled finances, shaped legislation, and managed foreign affairs. Its power evolved throughout Rome's history, from the Republic to the Empire.

The Senate faced challenges from other institutions and powerful individuals, adapting to maintain relevance. During crises, it granted emergency powers and managed conflicts. However, its authority diminished as military leaders gained prominence, ultimately transforming Rome's political landscape.
