George III's reign saw a period of immense social, economic, and political upheaval, including the American Revolution, the French Revolution, and the Napoleonic Wars. Despite these challenges, he was a popular monarch who is remembered as a symbol of British national identity and patriotism.
George III is known for his madness, which first manifested itself in 1765 and recurred throughout his life. He suffered from delusions, hallucinations, and irrational behavior, which led to periods of incapacity and required him to be placed under medical care. Despite his illness, he was able to carry out his duties as king with the support of his ministers and the Regency Act of 1765, which established a procedure for governing in his absence.
George III died on 29 January 1820 at Windsor Castle at the age of 81. He was succeeded by his eldest son, George IV.
