Interregnum queen

An interregnum queen is ideally the Great Royal Wife of a former Egyptian pharaoh, according to a 1932 report. In this given scenario, she effectively rules as regent in the place of her son until he reaches the age to assume the role of pharaoh. As it stands, the son is already presumed to be the de jure pharaoh, sharing power with his mother. In practice, the interregnum queen acts as sole ruler until the son comes of age. The term may have been the equivalent of the term "King's Mother" or even "Queen Mother". In some respects, the title is very much similar to that of a queen regent, as both roles require the leadership of a female monarch acting on behalf of the royal offspring.
