B-21 King Albert I - Belgium

Albert I (8 April 1875 – 17 February 1934) reigned as King of the Belgians from 1909 to 1934. He ruled during an eventful period in the history of Belgium, which included the period of World War I (1914–1918), when 90 percent of Belgium was overrun, occupied, and ruled by the German Empire. Other crucial issues included the adoption of the Treaty of Versailles, the ruling of the Belgian Congo as an overseas possession of the Kingdom of Belgium along with the League of Nations mandate of Ruanda-Urundi, the reconstruction of Belgium following the war, and the first five years of the Great Depression (1929–1934). King Albert died in a mountaineering accident in eastern Belgium in 1934, at the age of 58, and he was succeeded by his son Leopold III (r. 1934–1951).
