It reflected ongoing class struggles and contributed to the evolution of Roman institutions and civic culture celebrated in historical poetry.

The Lex Ogulnia, which opened priesthoods to plebeians in 300 BC, marked a significant shift towards religious inclusivity. This change is echoed in the works of poets like Catullus, who often explored themes of piety and civic duty, reflecting the evolving landscape of Roman religion.
