The Regency in the United Kingdom of Great Britain and Ireland was a period at the end of the Georgian era, when King George III was deemed unfit to rule due to his illness, and his son ruled as his proxy, as prince regent. Upon George III's death in 1820, the prince regent became King George IV. The term Regency can refer to various stretches of time; some are longer than the decade of the formal Regency, which lasted from 1811 to 1820. The period from 1795 to 1837, which includes the latter part of George III's reign and the reigns of his sons George IV and William IV, is sometimes regarded as the Regency era, characterised by distinctive trends in British architecture, literature, fashions, politics, and culture.

Almack's was the name of a number of establishments and social clubs in London between the 18th and 20th centuries. Two of the social clubs would go on to fame as Brooks's and Boodle's. Almack's most famous establishment was based in assembly rooms on King Street, St James's, and was one of a limited number of upper class mixed-sex public social venues in the British capital in an era when the most important venues for the hectic social season were the grand houses of the aristocracy. The site of the club, Almack's Assembly Rooms or Willis's Rooms, has become retrospectively interchangeable with the club, though for much of the club's lifetime, the rooms offered a variety of other entertainments with no connection to the club.

Regency dance is the term for historical dances of the period ranging roughly from 1790 to 1825. Some feel that the popular use of the term "Regency dance" is not technically correct, as the actual English Regency lasted only from 1811 until 1820. However, the term "Regency" has been used to refer to a much broader period than the historical Regency for a very long time, particularly in areas such as the history of art and architecture, literature, and clothing. This is because there are consistencies of style over this period which make having a single term useful.

Maria Anne Fitzherbert was a longtime companion of George IV of the United Kingdom before he became king. In 1785, they secretly contracted a marriage that was invalid under English civil law because his father, King George III, had not consented to it.

Before marrying the prince, Fitzherbert had been twice widowed. Her nephew-in-law from her first marriage, Cardinal Weld, persuaded Pope Pius VII to declare the marriage sacramentally valid.
