 Upon the conclusion of the Treaty of Versailles in early 1919, Article 227 expressly provided for the prosecution of Wilhelm "for a supreme offence against international morality and the sanctity of treaties", but the Dutch government refused to extradite him, despite appeals from the Allies.King George V wrote that he looked on his cousin as "the greatest criminal in history", but opposed Prime Minister David Lloyd George's proposal to "hang the Kaiser".It was reported, however, that there was little zeal in Britain to prosecute.
