Crisis of the Roman Republic

The prolonged political and social upheaval that weakened Rome’s republican institutions and culminated in Augustus’s establishment of sole rule in 27 BCE.

Roman civil wars: A series of armed conflicts between Roman factions and rival commanders that repeatedly brought Roman armies into Italy. Repeated civil wars made political disputes matters of military victory and survival.
Roman conquest of the Mediterranean: Rome’s expansion through wars that brought the Mediterranean basin under its control between the third and first centuries BCE. Conquest enriched Rome but intensified competition for land, wealth, and political influence.
Gaius Marius: A Roman general and politician who held the consulship seven times and led campaigns against foreign enemies. His repeated consulships and army reforms formed part of the new competition for military-backed power.
Conflict of the Orders: A long political struggle between patricians and plebeians that shaped Rome’s early republican institutions. Its earlier compromises provide a contrast to the later crisis’s escalating recourse to force.
Roman Empire: The state ruled by Roman emperors, conventionally dated from Augustus’s consolidation of power in 27 BCE. The crisis’s endpoint was the replacement of republican government by imperial rule.
Roman army: The military forces of ancient Rome, which changed from a citizen levy into a professional force during the late Republic. Soldiers increasingly depended on generals for rewards, strengthening commanders against republican institutions.
Latifundium: A large agricultural estate in ancient Rome, often worked by enslaved laborers. Large estates contributed to rural displacement and concentrated wealth in elite hands.
Lucius Cornelius Sulla: A Roman general who marched on Rome, became dictator, and reshaped the Republic through legislation. His march on Rome made armed seizure of the capital a precedent.
Battle of Pharsalus: A battle in 48 BCE in which Julius Caesar defeated Pompey’s forces during the Roman civil war. Caesar’s victory removed his chief rival and accelerated his concentration of power.
Imperial cult (ancient Rome): Religious practices that honored Roman emperors and members of their families as divine or divinely favored. Personal rule acquired religious forms that helped bind subjects to the new imperial order.
