A "Triumvirate" refers to a political regime dominated by three powerful individuals. This term is most commonly associated with ancient Rome, where it described a coalition of three leaders who shared control over the government. The most famous example is the First Triumvirate, which included Julius Caesar, Pompey, and Crassus in the 1st century BCE. Triumvirates can form in various contexts, not just in ancient Rome. They often arise in political systems where power is concentrated among a few leaders, allowing them to collaborate on decision-making. However, such arrangements can lead to conflicts and power struggles, as seen in the Second Triumvirate, which included Octavian, Mark Antony, and Lepidus.
