The Liberal State is the historical period in Costa Rica that occurred approximately between 1870 and 1940. It responded to the hegemonic dominion in the political, ideological and economic aspects of liberal philosophy. It is considered a period of transcendental importance in Costa Rican history, as it's when the consolidation of the National State and its institutions finally takes place. The arrival of the Liberals in power meant a profound change that affected all the essential aspects of Costa Rican politics, economy, society and culture.
