December Crisis (1768) (Swedish: Decemberkrisen) was a political crisis which occurred in Sweden in December 1768 when Adolf Frederick, King of Sweden, demonstrated against his limited powers by refusing to sign state documents, thereby paralyzing the government and bringing about a new Riksdag of the Estates.
In 1767, French envoy Louis Auguste Le Tonnelier de Breteuil suggested a coup to increase royal power to the Hovpartiet.
In December 1768, the king refused to sign state documents in protest to his limited power and on 15 December, the king formally resigned his throne in order to bring about the gathering of a new Riksdag, during which a reform to increase his capacity could be introduced.
This created a difficult political situation, as he had thereby technically abdicated and the nation was in interregnum.
The Hovpartiet suggested that the crisis could be used to stage a coup to establish absolute monarchy.
