Edward VI of England vs George III

Edward VI was crowned king of England at age nine, succeeding his father Henry VIII. His reign was dominated by regents, first Edward Seymour, Duke of Somerset, and later John Dudley, Duke of Northumberland.

Edward VI's government passed the Act of Uniformity, imposing the Book of Common Prayer in English. This reform advanced the Protestant Reformation in England, replacing Latin services with English ones and standardizing worship.

Edward VI's government issued the Forty-Two Articles, defining the doctrinal basis of the Church of England. These articles were more Protestant than earlier reforms, but were repealed after Edward's death under Mary I.

Edward VI, on his deathbed, drafted a will excluding his half-sisters Mary and Elizabeth from the succession, naming Lady Jane Grey as his heir. This attempt to maintain Protestant rule failed after his death, leading to Mary I's accession.

George III's reign saw the outbreak of the American Revolutionary War after colonial protests against British taxation. Britain lost the war after the French intervention. The Treaty of Paris in 1783 recognized American independence, ending British control of the Thirteen Colonies.

George III gave royal assent to the Acts of Union, which united Great Britain and Ireland into the United Kingdom of Great Britain and Ireland. This created a single parliament in London and ended the Irish Parliament. The union took effect on January 1, 1801.

George III's reign included the Napoleonic Wars against France under Napoleon Bonaparte. Britain fought coalitions across Europe and at sea. The wars ended with Napoleon's defeat at Waterloo in 1815, establishing British naval supremacy and colonial expansion.

George III suffered a final relapse of mental illness, likely due to porphyria. He became permanently incapacitated, leading to the Regency Act of 1811. His son George IV became Prince Regent, ruling in his stead until George III's death in 1820.

George III died at Windsor Castle at age 81, blind and deaf. He was buried in St George's Chapel. His 60-year reign was the longest of any British monarch at that time. His death ended the Regency era and passed the throne to George IV.
