Regency England refers to the period in British history from 1811 to 1820 when King George III was deemed unfit to rule due to mental illness. His son, the Prince of Wales, served as regent during this time. This era is known for its distinctive cultural developments, including literature, fashion, and architecture. The Regency period saw the rise of notable authors like Jane Austen and Lord Byron, who shaped English literature. It was also marked by significant social changes, including the expansion of the middle class and the beginnings of the Industrial Revolution, which transformed the economy and society.
