The First Triumvirate was an informal political alliance formed in 60 BCE between three prominent Roman leaders: Gaius Julius Caesar, Gnaeus Pompeius Magnus (commonly known as Pompey), and Marcus Licinius Crassus. This coalition aimed to consolidate their power and advance their individual political agendas in the Roman Republic, as they faced opposition from the Senate and other political factions. The alliance allowed the three men to support each other's ambitions, leading to significant military and political successes. However, the Triumvirate was not an official institution and began to unravel after Crassus's death in 53 BCE, ultimately leading to a power struggle between Caesar and Pompey that contributed to the end of the Republic.
