Leopold III was the King of Belgium from 1934 until his abdication in 1951. His controversial actions during World War II resulted in the political crisis, Royal Question. The son of Albert I and his queen consort Duchess Elisabeth in Bavaria, he studied at Eton College. Leopold served as a soldier during the final campaign of First World War. He married his first wife Princess Astrid of Sweden in 1926 and had three children. After he became the king upon his father’s death in 1934, he withdrew Belgium from the Pact of Locarno, a peace agreement among a few countries, including Germany and France. Leopold was forced to surrender his forces after World War II and was held captive by the Germans until 1944. In 1941, he secretly married for the second time. Leopold then remained in Switzerland from 1945 to 1950, awaiting the resolution of the “Royal Question” regarding his pending return to the royal throne. Although he won 58% of the votes in his favor, the opposition led him to renounce his sovereignty and eventually abdicate in 1951. He was succeeded by his son Baudouin.
