Campaign history of the Roman military details the chronological sequence of military campaigns conducted by the Roman military throughout the territorial expansion and defense of the Roman Empire. The Roman military's history is marked by a series of conflicts that not only expanded the empire's borders but also influenced its political, legal, and social structures.

Early Republic (509–264 BC)

The early Roman Republic focused on the consolidation of its territory in the Italian peninsula. Conflicts with neighboring Latin, Etruscan, and Samnite communities were frequent. The most notable of these early conflicts include the Roman-Etruscan Wars, the Roman-Latin Wars, and the Samnite Wars. These campaigns were crucial in establishing Rome's dominance over central Italy.

Mid Republic (264–133 BC)

The mid-Republican era was characterized by Rome's expansion beyond the Italian peninsula, beginning with the First Punic War (264–241 BC) against Carthage, which marked Rome's emergence as a naval power. This was followed by the Second Punic War (218–201 BC), where the Carthaginian general Hannibal famously crossed the Alps into Italy. Despite initial successes, Hannibal was eventually defeated. The Third Punic War (149–146 BC) led to the destruction of Carthage and the annexation of its territory.

Late Republic (133–27 BC)

The late Republic saw internal turmoil and civil wars, alongside external campaigns. The Gallic Wars, led by Julius Caesar, resulted in the annexation of Gaul (modern France). The period also witnessed the Civil War between Caesar and Pompey, the Liberators' civil war, and the Sicilian revolt, reflecting the political instability that ultimately led to the end of the Republic and the rise of the Roman Empire.

Early Empire (27 BC–AD 284)

The early Empire, or Principate, saw a consolidation of imperial borders and further expansion. The Roman conquest of Britain (43 AD) under Emperor Claudius and the Dacian Wars (101–106 AD) under Emperor Trajan were significant campaigns. The period also saw military operations in the Germanic Wars, including the Battle of the Teutoburg Forest where three Roman legions were lost.

Late Empire (AD 284–476)

During the late Empire, or Dominate, the Roman military faced increasing pressure from external threats such as the Goths, Huns, and Vandals. The Gothic War (376–382) and the Battle of Adrianople (378 AD), where the Roman army suffered a devastating defeat, marked the beginning of the end for the Western Roman Empire. The continuous barbarian invasions and internal divisions eventually led to the fall of the Western Roman Empire in 476 AD.

Legacy

The campaign history of the Roman military not only shaped the Roman Empire but also left a lasting legacy on warfare, engineering, and administration that influenced subsequent European history. The military strategies, tactics, and organization developed by the Romans are studied to this day.
