 As a reaction to late Baroque and Rococo forms, architectural theorists from circa 1750 through what became known as Neoclassicism again consciously and earnestly attempted to emulate antiquity, supported by recent developments in Classical archaeology and a desire for an architecture based on clear rules and rationality.Claude Perrault, Marc-Antoine Laugier and Carlo Lodoli were among the first theorists of Neoclassicism, while Étienne-Louis Boullée, Claude Nicolas Ledoux, Friedrich Gilly and John Soane were among the more radical and influential.Neoclassical architecture held a particularly strong position on the architectural scene c. 1750–1850.
