Simplified Neoclassicism, also called Novecento Italiano style, is linked to the classical architectural culture, but lightens its elements and architectural details, removing or simplifying the decoration. This is the architecture preferred by totalitarian regimes for its celebratory efficacy in the built environment, with the exaltation of the Roman age in the Italian case. Its major theorist will be in Italy the architect Marcello Piacentini who dominates the fascist twenty years with his canons, crowding out the rationalists, who attempted to reconcile the themes of the Modern Movement within an authoritarian regime. This style also affected new urbanistic projects (university city of Rome, E42) and the demolition and reconstruction of historic centers (Via della Conciliazione, historic centers of Brescia and Livorno).
