Why the consequences of Sulla's actions especially his eliminating the power of the popular assemblies?

Sulla's actions, particularly his dismantling of the popular assemblies, significantly weakened the power of the Roman populace in political decision-making, consolidating authority within the Senate. This shift led to an increase in oligarchic control and diminished the role of the plebeians, setting a precedent for future power struggles between the elite and the masses. His reforms, aimed at restoring aristocratic governance, ultimately contributed to the decline of the Republic and the rise of autocratic leaders, as subsequent political figures exploited these changes to gain control. Sulla's legacy thus highlights the fragility of democratic institutions in the face of authoritarianism.
