Leopold I (1790–1865) was a German prince who became the first King of the Belgians following Belgian independence in 1830. After the Greek War of Independence (1821–32), LeopoId was offered the position of King of Greece but turned it down, believing it to be too precarious. Instead, Leopold accepted the kingship of the newly established Kingdom of Belgium in 1831. He died in 1865 and was succeeded by his son, Leopold II.

Leopold II (1835–1909) was the second King of the Belgians, known for the founding and exploitation of the Congo Free State as a private venture. He succeeded his father to the Belgian throne in 1865 and reigned for 44 years until his death. His was the longest reign of any Belgian monarch. He died without surviving male issue; the current Belgian king descends from his nephew and successor, Albert I.

Albert I (1875–1934) reigned as King of the Belgians from 1909 to 1934. This was 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. 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.
