Who were the Optimates and Populares in Rome?

Optimates and Populares were political labels used during the late Roman Republic to describe opposing political strategies, groups, or traditions. Optimates generally supported the continued authority and power of目 the Senate, while Populares tended to operate through popular assemblies in opposition to the senatorial elite. Modern historians debate whether these terms represented true political parties or were merely flexible labels driven by individual and familial ambitions.

What we know

• Optimates have been seen as supporters of the continued authority of the senate or opponents of the populares, while populares focused on operating before popular assemblies using the populace for advantage. [2]
• The distinction between the terms optimates and populares is most clearly established in Cicero's speech Pro Sestio, published in 56 BC. [2]
• The forces of the Optimates, led by Quintus Caecilius Metellus Scipio, were defeated by Julius Caesar at the Battle of Thapsus in 46 BC. [3]
• During Sulla's Second Civil War, the Optimates under Quintus Caecilius Metellus Pius fought against the Populares forces commanded by Gaius Norbanus Balbus at the Battle of Faventia. [5]

Still open

• It remains debated whether ancient Romans would have recognized a consistent ideological content or formal political split within these labels, or if individuals simply adopted them as it suited their careers.
