Georgian architecture is the name given in most English-speaking countries to the set of architectural styles current between 1714 and 1830. It is eponymous for the first four British monarchs of the House of Hanover—George I, George II, George III, and George IV—who reigned in continuous succession from August 1714 to June 1830. The style was revived in the late 19th century in the United States as Colonial Revival architecture and in the early 20th century in Great Britain as Neo-Georgian architecture; in both it is also called Georgian Revival architecture. In America the term "Georgian" is generally used to describe all building from the period, regardless of style; in Britain it is generally restricted to buildings that are "architectural in intention", and have stylistic characteristics that are typical of the period, though that covers a wide range. 

The style of Georgian buildings is very variable, but marked by a taste for symmetry and proportion based on the classical architecture of Greece and Rome, as revived in Renaissance architecture. Ornament is also normally in the classical tradition, but typically rather restrained, and sometimes almost completely absent on the exterior. The period brought the vocabulary of classical architecture to smaller and more modest buildings than had been the case before, replacing English vernacular architecture (or becoming the new vernacular style) for almost all new middle-class homes and public buildings by the end of the period.
