Marcus Antonius was a Roman politician and military figure born in Rome around 83 B.C.

He spent his life at the center of Roman public affairs, working across both political and military roles during one of the most turbulent periods in the republic's history. The facts available place his birth in Rome, with some sources dating it to January 12, 83 B.C., while the Library of Congress records him under the authorized label "Antonius, Marcus, 83 B.C.?-30 B.C." — the question mark reflecting the uncertainty that surrounds the precise date. He conducted his affairs in Latin, the language of Roman civic and military life, and held standing as a citizen of Ancient Rome throughout his career.

He died in Alexandria in 30 B.C., with July 30 cited as the specific date in some records. His life, spanning roughly five decades, touched both the political institutions of Rome and its military operations, and his career unfolded during a period when those two spheres were deeply intertwined. The combination of political engagement and military service defined the arc of his public role, and it is in that dual capacity — as a man who moved between the forum and the field — that the historical record most consistently places him. His death in Alexandria, far from the city of his birth, marks the geographical endpoint of a life lived largely in service to Roman power.
