Historical: American - (1811-1820) Regency era The Regency era began when the Prince of Wales was appointed Regent of England after his father, King George III, fell insane. Encompassing the years of 1811-1820, the period signaled the end of Georgian exuberance and the advent of Victorian sensibilities.
The United States maintained its independence against England during the Regency era. After declaring war in 1812, the two nations engaged in a two-year naval battle along the Canadian border. In 1814, the Treaty of Ghent brought the futile war to an end. However, America remained entangled in several domestic controversies such as the First Seminole War in 1817 and the mounting tensions over slavery fueled by the Missouri Compromise in 1820.
