A triumvirate (Latin: triumvirātus) is a political regime ruled or dominated by three powerful individuals known as triumvirs (Latin: triumviri). The arrangement can be formal or informal. Though the three are notionally equal, this is rarely the case in reality. The term can also be used to describe a state with three different military leaders who all claim to be the sole leader.
