19 November 1921, Madeira

If you want to get an overthrown emperor out of the way, an island is ideal. Napoleon I of France was sent into exile by the powers that had defeated him – first to the island of Elba in the Mediterranean Sea and then to St Helena in the Atlantic Ocean. In 1921, Karl Habsburg, the last monarch of the Austro-Hungarian empire, was banished by the victors of the First World War to the island of Madeira off the west coast of Africa. Just like Napoleon a hundred years before him, Karl had attempted to regain power after being deposed in Hungary. But he was unsuccessful and died in exile in Madeira in 1922.
