The Congress turned it into an independent country under the name Duchy of Brunswick. Charles II (1815–1830) [ edit ] The underage Duke Charles , the eldest son of Duke Frederick William (who had been killed in action), was put under the guardianship of George IV , the Prince Regent of the United Kingdom and Hanover.
