Vitéz nagybányai Horthy Miklós (18 June 1868 - 9 February 1957) was a Hungarian admiral and statesman, who became the Regent of Hungary.
He served as Regent of the Kingdom of Hungary between World Wars I and II and throughout most of World War II, from 1 March 1920 to 15 October 1944. He was styled "His Serene Highness the Regent of the Kingdom of Hungary".
The interwar period dominated by Horthy's government is known in Hungarian as the Horthy-kor ("Horthy age") or Horthy-rendszer ("Horthy system"). Its legacy, and that of Horthy himself, remain among the most controversial political topics in Hungary today, tied inseparably to the Treaty of Trianon and the Holocaust.
