After only a year of young married life the young prince Napoleon joined the army, at the insistance of his uncle. He served in the Imperial Guards and was made an honorary colonel. He served mainly in Paris but was also posted all over france. In 1829 he was promoted to the rank of honorary general of the imperial guard, a rank held only by the emperor and the king of rome. He was valued highly by the emperor who insisted that he and princess Eugenie attend his court permanently from 1830 onwards.
He was present, along with the king of rome, at the emperors deathbed. He supported his cousin when he became emperor and, as heir to the throne, played a key role in politics. This was until 1835, when the increasingly sickly emperor Napoelon II insisted his mother become his main associate. Prince Napoleon left Tuileries and moved to a large house near lake Geneva until the emperors death in 1836.
