A triumvirate is a political alliance or governing body made up of three individuals who share power. Historically, the term is most commonly associated with ancient Rome, where the First Triumvirate included Julius Caesar, Pompey, and Crassus, and the Second Triumvirate involved Octavian (later Augustus), Mark Antony, and Lepidus. Triumvirates can be formed for various purposes, including military, political, or diplomatic objectives, and they often face challenges in maintaining balance and cooperation among the members.
