The Regency Era refers to a period in British history from 1811 to 1820 when King George III was deemed unfit to rule due to mental illness. During this time, his son, the future King George IV, served as regent. This era is known for its distinctive cultural developments, including literature, fashion, and architecture. The Regency Era is often associated with notable figures such as the author Jane Austen, whose novels reflect the social dynamics of the time. The period also saw the rise of the Regency style in art and design, characterized by elegance and symmetry, influencing many aspects of British culture.
