Triumvirate
A triumvirate is rule, a commission or a political alliance of three people. In Roman history the word is most often linked with two late Republican alliances: the First Triumvirate of Caesar, Pompey and Crassus and the Second Triumvirate of Octavian, Antony and Lepidus.
In brief:
- the literal meaning is 'three men', tres viri;
- the First Triumvirate was a private agreement without a formal law;
- the Second Triumvirate was an extraordinary state commission;
- both alliances reveal the crisis of normal Republican institutions.

Why triumvirates became possible
The triumvirates did not result from a single intrigue but from a systemic crisis of the Republic. The Senate could no longer balance the interests of commanders, veterans, provinces, equestrians and the urban plebs. Victorious generals returned with armies, prestige and clients, while political decisions were increasingly forced through popular assemblies, street pressure and military power.
The First Triumvirate showed that a private coalition could overcome senatorial opposition. The Second went further by turning an alliance of three leaders into a legally constituted emergency commission. The subject therefore explains not only the careers of Caesar and Octavian, but also the transition from Republic to Empire.
