Evidence: Otto Friedrich Ludwig (Greek: Όθων, Óthon; 1 June 1815 – 26 July 1867) was a Bavarian prince who ruled as King of Greece from the establishment of the monarchy on 27 May 1832, under the Convention of London, until he was deposed on 23 October 1862. His government was initially run by a three-man regency council made up of Bavarian court officials. Upon reaching his majority, Otto removed the regents when they proved unpopular with the people, and he ruled as an absolute monarch.
