King George I of Denmark began his reign at the age of 19, a vigorous young man who had been the constant companion of his elder brother, the Prince of Wales.
As a part of his accession to the throne, the pretense of absolutism was dropped by the monarchy. The nobility would once again have a level of autonomy and influence comparable to that of Parliament in the Three Kingdoms. George was undeterred. A few months later the War of the Polish Succession broke out, and it was only at the behest of his father that the battle-hungry King did not enter the fray. Instead, per his father's advice, he focused more on the issue of rebuilding the finances of a country that had been dealing with a disinterested king and a two-year regency.
The first thing George did was to attempt to outmaneuver the nobility by becoming a patron of the commons. The deal to drop the
Lex Regia in Denmark never once stipulated what would replace it, and so the new
Lex Nordicum was in fact written largely by George himself. It established that the nobility would each nominate a representative, usually a son, to speak for their interests in a
Riksdag which George would preside over. The nobility would sit in the upper house, the
Jordrad, or land-council, while the representatives of property-owning commoners and bourgeoisie would sit in the
Folksrad, or people's council.
Thus Denmark transitioned to a constitutional system. Norway was a special case: Norway would have its own Rigsdag, subordinate to the King, giving it total control over its domestic policies. The power to make treaties and declare war, of course, was still a royal prerogative.
Denmark-Norway enjoyed favorable relations with the Three Kingdoms under George, both during the reigns of his father and brother, and the regency of his nephew under his sister-in-law Charlotte.
In 1748, the King of Sweden, Frederick I, died, leaving the throne vacant. George was immediately interested. The candidates for king all appeared to be absolutists of one stripe or another, and the absolutism of Charles IX had been renounced by the late Queen Ulrik Eleanora. George this gathered his army and marched on Upsaala, where the election was to be held. He communicated with nobles in Sweden who felt as he did, and with his reputation as a liberal and a constitutionalist, George was able to garner enough support to make his election legitimate, rather than a mere invasion.
Nevertheless, intense opposition to union with Denmark led to an armed insurrection against his rule. The War of the Swedish Succession was a civil war, rather than an international fiasco, however it was still ruinously expensive, especially for the Swedes, still smarting as they were from the loss of Livonia and Finland. Eventually a compromise would be reached: rather than himself, George would decline the throne of Sweden in favor of his son, George would take the Swedish throne.
These best-laid plans would come to an end in 1762, when a smallpox epidemic burned through Copenhagen and took the life of
Kronprins Frederick, George's elder son. George I of Sweden would thus inherit his father's kingdom as well.
During this time the would-be warrior king had instead bolstered Denmark's trade immensely, enriching the Kingdom and strengthening the power of the commons vis-a-vis the nobility. The Danish Africa Company would play a large role in the expansion of the French colonies along the Gulf Coast, importing slaves by the tens of thousands and enriching many Danish merchants. Their part in the tobacco, indigo, and cotton trade would also pay handsomely, as French policy was to subordinate the interests of these cash crops in favor of the sugar trade. Danish subcontractors were thus heavily invested in the growth of French influence along the Gulf Coast, and Danish nearly became the second language of cities like Mobile, Baton Rouge, New Orleans, and Fernandville (OTL Galveston). French, consequently, was the language of the merchants, and it would be the tensions between the seemingly foppish and effete merchants and the seemingly hardier, patriotic landowners that the nobility would exploit during the Emperors' War.
George died in 1777, of a brain aneurysm. His son, George I of Sweden, would thus take the throne at the age of 42. For the first time in over two centuries, the crowns of Sweden, Denmark, and Norway would be united.
