Abraham IV of Atlantica Alba

Abraham IV (b. 23 February 1910 in Copenhagen, age 111) was King of Atlantica Alba and the Personal Realms and head of the House of Silkeborg from 15 March 1933 to 10 May 1981, reigning for just over 48 years. He was succeeded by his eldest son Andrew upon his abdication, which was for health reasons as Abraham believed he no longer possessed the mental faculty properly expected of a proper monarch.
