The term triumvirate (Latin for "rule by three men") or troika in Russian, is commonly used to describe an alliance between three equally powerful political or military leaders. These alliances seldom hold very long. The term can also be used to describe a state with three different military leaders who all declare to be the sole leader of the state.
