Napoleon I originally wanted Napoleon II to succeed him, but this was rejected by the coalition. Napoleon II and his mother went into exile in Austria, while Napoleon I was exiled to Elba. In 1815, Napoleon I escaped and retook control of France, but was forced to resign again after his defeat at the Battle of Waterloo.
