What led to the fall of the Roman Republic?

The fall of the Roman Republic was driven by deep structural tensions, including wealth inequality, class conflict, and the erosion of traditional political norms. Over decades, ambitious leaders raised private armies loyal to themselves rather than the state, culminating in civil instability and the birth of the Roman Empire. Scholars have debated whether disenfranchised citizens seeking rights or the political elite resisting reform bear the primary responsibility for the internal dissension.

What we know

• The crisis of the Roman Republic spanned from approximately 133 BC to 30 BC and resulted in the demise of the Republic and the advent of the Roman Empire. [1, 2]
• Key structural tensions included the breakdown of the mos maiorum, widening wealth and land inequality, and class conflict between the optimates and the populares. [2]
• Leaders such as Marius, Sulla, Pompey, and Julius Caesar worsened the instability by establishing armies personally devoted to them instead of the state. [2]

Still open

• Ancient and modern commentators like Sallust and Edward Gibbon viewed the expansion of citizenship negatively as a cause of internal dissension and revolts, whereas other scholars argue the poor were justified in seeking to redress legal grievances.
