Frederick VII (October 6, 1808 - November 15, 1863) was the last king of Denmark to rule as an absolute monarch. He reigned from 1848 until his death. During his rule, he signed a constitution that gave Denmark a government and made the country a constitutional monarchy, which at that time meant that only mature males possessing land would be able to vote. The constitution was signed as a result of the peaceful revolution of March.
Frederick was married three times, and had numerous affairs to boot, but was apparently sterile...the fact that he reached middle age without producing an heir meant that king Frederick VI's nephew prince Christian of Glücksburg (1818-1906) was chosen to suceed him in 1852, and when Frederick died in 1863, Christian took the throne as Christian IX.
Frederick's motto was: "The love of the nation; my strength."
The dynastic female heiress according to the original primogeniture from Frederick III was the childless daughter of late kingFrederick VI, after whom the original primogeniture would have lead to heirs of Louise, sister of Frederick VI, who had married the then duke of Augustenburg.
FrederickVII died in 1863 and was interred in Roskilde Cathedral.
Frederick became the symbol of the nationalist German independence-movement in Schleswig-Holstein, after his father in exchange for money had renounced his claims as first in line to inherit the twin-duchies of Schleswig and Holstein, following the London protocol of May 8th, 1852, which concluded the First war of Schleswig.
In November 1863Frederick claimed the twin-duchies in succession after KingFrederickVII of Denmark, who also was the Duke of Schleswig and Holstein, and who had died without a male heir.
Frederick and his heirs continued to use the title, which after the next generation went over to the Glucksburg branch, to heirs of the elder brother of Christian IX of Denmark.
