The First Triumvirate was an informal political alliance among three prominent politicians in the late Roman Republic: Gaius Julius Caesar, Gnaeus Pompeius Magnus and Marcus Licinius Crassus. The constitution of the Roman republic had many veto points. In order to bypass constitutional obstacles and force through the political goals of the three men, they forged in secret an alliance where they promised to use their respective influence to support each other. The "triumvirate" was not a formal magistracy, nor did it achieve a lasting domination over state affairs.
