In Swedish and Finnish history, the Age of Liberty (Swedish: Frihetstiden) is a half-century-long period of parliamentary governance and increasing civil rights, beginning with Charles XII's death in 1718 and ending with Gustav III's self-coup in 1772. The shift of power from monarch to parliament was a direct effect of the Great Northern War, which was disastrous for Sweden.
Suffrage under the parliamentary government of the Age of Liberty was not universal. Although the taxed peasantry was represented in the Parliament, its influence was disproportionately small, while commoners without taxed property had no suffrage at all.
Charles XI of Sweden had carefully provided against the contingency of his successor's minority; and the five regents appointed by him, if not great statesmen, were at least practical politicians who had been trained in his austere school. At home the "Reduction" was cautiously pursued, while abroad the successful conclusion of the great peace congress at Ryswick was justly regarded as a signal triumph of Sweden's peaceful diplomacy. The young king was full of promise, and had he been permitted gradually to gain experience and develop his considerable talents under the guidance of his guardians, as his father had wanted, all might have been well for Sweden. Unfortunately, the sudden, noiseless revolution of 6 November 1697 which made Charles XII of Sweden absolute master of his country's fate in his fifteenth year, and the league of Denmark, Saxony and Russia, formed two years later to partition Sweden, led Sweden to war and her defeat.
