Christian married his second wife, Princess Caroline Amalie of Schleswig-Holstein-Sonderburg-Augustenburg (daughter of Louise Augusta of Denmark, the only sister of Frederick VI) at Augustenborg Palace on 22 May 1815. The couple was childless and lived in comparative retirement as leaders of the literary and scientific society of Copenhagen until Christian ascended the throne of Denmark. Christian's suspected democratic principles made him persona ingratissima at all the reactionary European courts, the court of Denmark included. It was not until 1831 that King Frederick gave Christian a seat on the council of state. On 13 December 1839 he ascended the Danish throne as Christian VIII. The Liberal party had high hopes of “the giver of constitutions,” but he disappointed his admirers by steadily rejecting every Liberal project. Administrative reform was the only reform he would promise. In his attitude to the growing national unrest in the twin duchies of Schleswig and Holstein he often seemed hesitated and half-hearted, which damaged his position there. It was not until 1846 that he clearly supported the idea of Schleswig being a Danish area. Some historians and biographers believe, however, that king Christian would have given Denmark a free constitution had he lived long enough, and his last words are sometimes (rather tragically) recorded as "I didn't make it". ("Jeg nåede det ikke.") King Christian VIII continued his predecessor's patronage of astronomy, awarding gold medals for the discovery of comets by telescope and financially supporting Heinrich Christian Schumacher with his publication of the scientific journal Astronomische Nachrichten. Seeing that his only legitimate son, the future Frederick VII, was apparently unable to beget heirs, he commenced arrangements to secure the succession in Denmark. The result was the selection of the future Christian IX as hereditary prince, the choice made official by a new law enacted on 31 July 1853 after an international treaty made in London. Christian was the 960th Knight of the Order of the Golden Fleece in Spain in 1840. He died of blood poisoning in Amalienborg Palace in 1848 and was interred in Roskilde Cathedral.
