Napoleon II of France (Crown of the Emperor)

Napoleon II (9 September 1822 – 17 March 1891) was the Emperor of the French and the last King of Westphalia. In the fourth year of his reign, the Prussian armed forces invaded Westphalia, beginning the brutal First World War. Between 1866 and 1870, there was nothing but stalemate on the front-lines. Eventually, the war ended in victory for Prussia and her allies, leaving France humiliated and defeated. Napoleon is often considered the worst French Emperor.
