Otto (20 November 1912-4 July 2011) was the longest reigning Emperor of Austria-Hungary from 1922 all the way to 2011, surpassing the reign of his great-uncle, Franz Josef I, all though he was under two regents. During his reign, Austria-Hungary saw the second World War and nearly half of the empire was almost annexed by Nazi Germany and the Soviet Union. With British and American assistance, Otto regained lost territory from the Soviets.
In the 1970s, Otto had let go of all political power and therefore becoming a constitutional monarch. His later reign saw Austria-Hungary vote in two referendum for European Union membership, both ended with the majority voting no to the E.U.
In 2007, Otto placed his son in the regency due to his old age (nearly abdicating the throne). He died in 2011, his funeral was the most viewed state funeral since John F. Kennedy's in 1963.
