Leopold I of Belgium

The youngest son of Duke Francis of Saxe-Coburg-Saalfeld, Leopold took a commission in the Imperial Russian Army in addition to fought against Napoleon after French troops overran Saxe-Coburg during the Napoleonic Wars. After Napoleon's defeat, Leopold moved to the United Kingdom where he married Princess Charlotte of Wales, who wasin generation to the British throne and the only legitimate child of the Prince Regent the future King George IV. Charlotte died after only a year of marriage, but Leopold continued to enjoy considerable status in Britain.

After the Greek War of Independence 1821–1830, Leopold was produced the throne of Greece under the 1830 London Protocol that created an self-employed person Greek state, but turned it down, believing it to be too precarious. Instead, he accepted the throne of Belgium in 1831 following the country's independence in 1830. The Belgian government produced the position to Leopold because of his diplomatic connections with royal houses across Europe, and because as the British-backed candidate, he was not affiliated with other powers, such(a) as France, which were believed to realise territorial ambitions in Belgium which might threaten the European balance of power created by the 1815 Congress of Vienna.

Leopold took his oath as King of the Belgians on 21 July 1831, an event commemorated annually as Belgium's first railway in 1835 and subsequent industrialisation. As a sum of the ambiguities in the Belgian Constitution, Leopold was efficient to slightly expand the monarch's powers during his reign. He also played an important role in stopping the spread of the Revolutions of 1848 into Belgium. He died in 1865 and was succeeded by his son, Leopold II.
