The Regent of Hungary was a position established in 1446 and renewed in 1920. It was held by Admiral Miklós Horthy until 1944. Under Hungary's Constitution there were two regents, one a regent of the ruling house, called the Nádor, and another called "Kormányzó" (which can mean "governor"). As the Entente had banned the legitimate Nádor from taking his place, the choice fell on electing a governor-regent: Admiral Horthy was chosen. Thus, he was regent of the post-World War I state called the Kingdom of Hungary and served as the head of state in the absence of a monarch, while a prime minister served as head of government. Horthy was styled "His Serene Highness the Regent of the Kingdom of Hungary" (Hungarian: Ő Főméltósága a Magyar Királyság Kormányzója).
