It ahs also been the case that regents have served during an interregnum - that is, while a nation is formally a monarchy but no monarch has been appointed. This was the case in Hungary between 1919 and 1945, when the regent was Admiral Horthy; Finland was also officially ruled by a regent between 1917 and 1918, when it was established as a republic.
