The Portuguese New State, an authoritarian nationalist regime resulting from the 28 May Revolution and led by Oliveira Salazar, embarked upon a wide-ranging public works policy, beginning in the 1930s. Initially, in new public buildings, a monumental modernist style prevailed, with Art Deco characteristics. However, after the Portuguese World Exhibition in 1940, whose chief architect was Jose Cottinelli Telmo, the Portuguese Government started to prefer a nationalistic style for its new public constructions. This style was used in all types of public buildings, from small rural elementary schools to big secondary schools and university campuses, military barracks, courts of justice, hospitals, town halls and so on.
