After the fall of monarchy in Russia, Constantine lost his last supporter inside the Entente opposed to his removal from the throne. In the face of Venizelist and Anglo-French pressure, King Constantine finally left the country for Switzerland on 11 June 1917; his second-born son Alexander became king in his place. The Allied Powers were opposed to Constantine's first born son George becoming king, as he had served in the German army before the war and like his father was thought to be a Germanophile.
