In a monarchy, a regent is a person appointed to execute the office of the monarch temporarily. Regencies may arise for a number of reasons, including the monarch being a minor, ill, absent from the country, or otherwise unavailable. A regent may also be appointed in cases where the throne is vacant, or the identity of the legitimate monarch is disputed.
