The Optimates means "the best" in Latin and they were a political faction that defended the interests of the senatorial oligarchy and sought to keep power in the hands of the elites.
The Optimates presented greater class cohesion and homogeneity compared to the popular ones, who were more diverse in their interests.
As they were pro-Republic, they focused on preserving the order and traditions of the republic, opposing reforms that sought to benefit the popular classes.
Known figures such as Cicero and Sulla are representative of the optimates, who played crucial roles in the politics of their time.
