The Ephors were a group of five elected officials in ancient Sparta, responsible for overseeing the actions of the Spartan kings and the government. They held significant power, including the ability to convene the Gerousia (council of elders) and the assembly, and they could even bring charges against the kings if necessary. Their role was crucial in maintaining a balance of power within the Spartan political system. Ephors were elected annually and were chosen from the citizenry of Sparta. This system allowed for a degree of accountability and representation among the ruling class. Their authority extended to various aspects of Spartan life, including education, public morality, and military affairs, making them key figures in the governance of the city-state.
