Emperor Otto (The German Century)

Otto I of Austria and II of Hungary (Franz Joseph Otto Robert Maria Anton Karl Max Heinrich Sixtus Xavier Felix Renatus Ludwig Gaetan Pius Ignatius; 20 November 1912 – 4 July 2011) was, among other titles, the last ruler of the United States of Greater Austria, a realm which comprised modern-day Hungary, Czechoslovakia and parts of Germany, Croatia, Serbia, Venice, Poland, Romania, and Ukraine. After the Crisis of 1933, the Federation was dissolved and Austria was annexed by Germany. Admiral Miklós Horthy restored the Kingdom of Hungary and placed Otto on the throne, making Otto the first king of an independent Hungary for almost 400 years.
