Carl XVI Gustaf of Sweden (born 1946)
Born 1946 CE.
Carl XVI Gustaf (Carl Gustaf Folke Hubertus; born 30 April 1946) is King of Sweden since 15 September 1973. Having reigned for 52 years, he is the longest-reigning monarch in Swedish history and the second longest-serving current head of state. Carl Gustaf was born during the reign of his paternal great-grandfather, King Gustaf V, as the youngest child and only son of Prince Gustaf Adolf, Duke of Västerbotten, and Princess Sibylla of Saxe-Coburg and Gotha. His father died in an airplane crash in Denmark in January 1947, when Carl Gustaf was nine months old. Carl Gustaf became crown prince and heir apparent to the Swedish throne at the age of four when his grandfather Gustaf VI Adolf acceded to the throne in 1950. Carl Gustaf acceded to the throne upon his grandfather's death on 15 September 1973. Shortly after he became king, the new 1974 Instrument of Government took effect, formally stripping the monarchy of its remaining executive powers.
