+## Government and Constitution
+The Roman Republic operated under a "mixed constitution" praised by the Greek historian Polybius (*Histories*, Book VI, c. 150 BCE) as combining monarchic, aristocratic, and democratic elements [^4]:
+- Consuls: Two annually elected magistrates holding executive and military authority (monarchic element)
+- Senate: ~300 members drawn from former magistrates, controlling finances and foreign policy (aristocratic element)
+- Assemblies: Popular legislative bodies (Comitia Centuriata, Comitia Tributa) holding formal legislative power (democratic element)
+
+The Conflict of the Orders (494–287 BCE) gradually secured equal political rights for plebeian citizens, culminating in the Lex Hortensia (287 BCE), which made plebiscites binding on all Romans @t[494 BCE..287 BCE] [^5].
+
+Under the Empire, the Senate retained formal prestige but real power shifted to the emperor (princeps). Diocletian's Dominate (284 CE) formalized autocratic rule, abandoning the republican fiction of the Principate @t[=0284].
