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, bypassing traditional political structures. The alliance was not officially recognized by Roman law and relied on mutual support. However, tensions arose, particularly after Crassus's death in 53 BCE and the growing rivalry between Caesar and Pompey, ultimately leading to a civil war that marked the end of the Republic.
