Birth and family Prince Frederick was born between 10 and 11 in the evening on 31 March 1723. He was the grandson of King
Frederick IV of Denmark and Norway and the only son of
Crown Prince Christian and
Sophie Magdalene of Brandenburg-Kulmbach. Frederick was the last Danish prince to be born in the then antiquated and overextended
Copenhagen Castle, which dated from the late 14th century, and had assumed a monstrous appearance and started to crumble under its own weight after several extensions. Demolition of the castle began in 1731 to make way for a more adequate royal residence, the vast
Baroque style Christiansborg Palace, from where Frederick would eventually reign. The young prince was
baptized the following day in the Crown Princess's Bedchamber by the royal
confessor Christen Lemvig, and was named after his grandfather, King Frederick IV. As the Crown Prince's only son, Frederick was destined to rule from birth. A younger sister died in infancy in 1724, and his only surviving sister,
Princess Louise, was born in 1726. On 12 October 1730, King Frederick IV died and Frederick's father ascended the throne as King Christian VI. Frederick himself became Crown Prince at the age of seven.
Upbringing and education . Christian VI and Queen Sophie Magdalene were deeply devoted to
Pietism, a movement within
Lutheranism that combines its emphasis on biblical doctrine with an emphasis on individual
piety and living a vigorous
Christian life. As a consequence, Frederick was given a strictly religious upbringing. At the age of 7, he received his own
royal household with the German
nobleman Georg Wilhelm von Söhlenthal as his
hofmeister. Söhlenthal was an ardent supporter of the
Moravian Brethren, and his home was the center of the pietistic circles in Copenhagen. He shared a deep religious piety with the king, and for a time he was Christian VI's adviser on ecclesiastical matters. However, Söhlenthal did not succeed in influencing the spiritual development of the Crown Prince, as he was an overly gentle and weak character, and in 1738 he was dismissed from his position as hofmeister. Frederick's education became rather deficient. In 1730 the king entrusted the significant and well-educated
privy councillor Iver Rosenkrantz supervision of Crown Prince Frederick's upbringing, but this had no influence on the actual teaching. Rosenkrantz was a supporter of the traditional
Lutheran orthodoxy, while Christian VI more and more became a proponent of
Pietism and lost confidence in Rosenkrantz. The Crown Prince's education was therefore completely carried out in the German Pietist spirit that prevailed at court. Like his ancestors at the then primarily
German-speaking court in Copenhagen, he only had a poor command of the Danish language, and knew German better than Danish all his life. None the less, his mother ironically referred to him as "Der Dänische Prinz" (literally
The Danish Prince in German) because he occasionally spoke Danish. Apart from a certain interest in
coin collecting, he only had modest cultural or intellectual interests. . Portrait by
Andreas Møller, probably 1740. Prince Frederick proved himself from an early age to have a completely different nature from his strict and somewhat gloomy parents. He was gentle and kind in nature, cheerful and accessible to everyone, and wanted to see his subjects happy. Unlike his secluded parents, who were rarely seen outside their palaces, he enjoyed spending time in public with people from all walks of life. Despite his upbringing in a strictly pietistic home, he was not himself gripped by pietism. Although certainly not unfamiliar with religious sentiments, Frederick grew into a
hedonist who enjoyed the pleasures of life such as deer stalking, wine and women. This hedonism, however, evolved to
debauchery, and Frederick became well known for a
libertine lifestyle marked by
sexual licentiousness and
alcoholism. With a group of other
rakes, he would tour the city's
taverns and
brothels, to an extent that his father at one point considered having him declared legally decapacitated. The King's more prudent advisers, however, spoke against it, as it would legally be a violation of the ''
King's Law'' (; ), the
absolutist constitution of
Denmark and Norway from 1665. Furthermore, it would also compromise the monarchy to an unprecedented degree to admit that the future king was unfit to rule. . Portrait by
C.G. Pilo, 1760. Of the outmost importance for the future of the Crown Prince and his realm, was the 1730 appointment as his
chamber page of
Adam Gottlob Moltke, a nineteen year old
nobleman from
Mecklenburg who was eleven years older than Frederick. Moltke had been a
page to his father, and the King and Queen counted on Moltke to teach the Crown Prince to control himself. In 1743 Moltke was promoted to
Hofmeister. In fact, Moltke did nothing to control Frederick's sexual appetite nor his alcohol consumption, but in return a lifelong relationship of trust was established between the two men, which was to become crucial after Frederick's ascension to throne. In 1740, the Crown Prince was
confirmed, and from then on as heir to the throne was given a seat in the
Council of State. During the Swedish succession crisis in 1743 following the death of Queen
Ulrika Eleonora of Sweden in 1741, when it was clear that no legitimate heir was to be expected, Crown Prince Frederick in 1743 had great prospects of being elected heir to the throne in Sweden. The
peasantry unilaterally elected Crown Prince Frederick, and in
Dalecarlia the peasants even instigated a rebellion, the
Dalecarlian rebellion or
stora daldansen () to enforce his election. However, as a result of the
Treaty of Åbo in 1743, which ended the
Russo-Swedish War of 1741–1743,
Adolf Frederick of Holstein-Gottorp was appointed heir to the throne in place of Crown Prince Frederick, after pressure from the
Russian empress Elizabeth Petrovna.

dynastic marriage was negotiated between him and
Princess Louise of Great Britain, the youngest daughter of King
George II and
Caroline of Ansbach. The marriage was proposed by
Great Britain from political reasons. At the time of the marriage, both
France and Great Britain wished to make an alliance with Denmark-Norway, and being
protestant Great Britain had the advantage of being able to make a marriage alliance. The Danish government was in favor of the proposal, while Frederick's father, King Christian VI, was initially reluctant. But he was convinced, as he hoped the marriage would lead to British support for his son's claim to the throne of Sweden. As for the Crown Prince, after having been presented with a portrait of the princess and finding her exterior appealing, and having been told of her amiability, he declared himself willing to marry Louise, all the more so as he too could see that the political circumstances made the marriage desirable. They were married in a
proxy wedding ceremony on 10 November 1743 in
Hanover, with the Princess's brother, the
Duke of Cumberland, acting as the representative of the groom. ==Reign==
