Leopold III of Belgium
Leopold III reigned as King of the Belgians from 1934 until 1951, when he abdicated in favour of the heir apparent, his son Baudouin. From 1944 until 1950, Leopolds brother, Charles, served as prince regent while Leopold was declared incompetent to rule. In 1950, the debate about whether Leopold could resume his royal duties provoked a political crisis known as the Royal Question.
Leopold III was born in Brussels as Prince Leopold of Belgium, Prince of SaxeCoburg and Gotha, and succeeded to the throne of Belgium onFebruary 1934 following the death of his father, King Albert I. He was invested as the 1,154th Knight of the Order of the Golden Fleece in Spain in 1923, the 355th Grand Cross of the Order of the Tower and Sword in 1927 and the 833rd Knight of the Order of the Garter in 1935.
