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.
Biedermeier The Biedermeier period refers to an era in Central Europe between 1815 and 1848 during which the middle class grew and arts appealed to common sensibilities. It began with the time of the Congress of Vienna at the end of the Napoleonic Wars, and ended with the onset of the European revolutions in 1848. Although the term itself is a historical reference, it is predominantly used to denote the artistic styles that flourished in the fields of literature, music, the visual arts and interior design.
