Upon his coronation in 1821, Emperor Napoleon II was only 10 years old, and the European Empire was in the midst of war. He was not old enough to assume power. Prince Karl Theodor of Bavaria was named regent. Historians believe this was done in order to further the notion that the European Emperor represented the European people, not just the French. Prince Augustus served until Emperor Napoleon II turned 18 and married his sister, Princess Sophie, in 1829. However, it was to be short. Napoleon II died in 1832 of tuberculosis. During this short time, they had only 2 children, Frederich in 1830 and Maurice in 1832.
