Regency era The Regency in Great Britain was a period when King George III was deemed unfit to rule and his son ruled as his proxy as Prince Regent. On the death of George III in 1820, the Prince Regent became George IV. The term Regency (or Regency era) can refer to various stretches of time; some are longer than the decade of the formal Regency which lasted from 1811–1820. The period from 1795 to 1837, which includes the latter part of the reign of George III and the reigns of his sons George IV and William IV, is often regarded as the Regency era, characterised by distinctive trends in British architecture, literature, fashions, politics, and culture. The Regency era ended in 1837 when Queen Victoria succeeded William IV.
Edwardian era The Edwardian era or Edwardian period of British history covers the brief reign of King Edward VII, 1901 to 1910, and is sometimes extended in both directions to capture long-term trends from the 1890s to the First World War. The death of Queen Victoria in January 1901 marked the end of the Victorian era. The new king Edward VII was already the leader of a fashionable elite that set a style influenced by the art and fashions of continental Europe. Samuel Hynes described the Edwardian era as a "leisurely time when women wore picture hats and did not vote, when the rich were not ashamed to live conspicuously, and the sun really never set on the British flag'".
