 Shortly after, the government allowed the creation of "assemblies of members of parliament" integrated by deputies and senators of the different territories of Spain, so that they could constitute "pre-autonomic regimes" for their regions as well.The Fathers of the Constitution had to strike a balance between the opposing views of Spain—on the one hand, the centralist view inherited from monarchist and nationalist elements of Spanish society, and on the other hand federalism and a pluralistic view of Spain as a "nation of nations"; between a uniform decentralization of entities with the same competencies and an asymmetrical structure that would distinguish the nationalities.Peripheral nationalist parties wanted a multinational state with a federal or confederal model, whereas the governing Union of the Democratic Centre (UCD) and the People's Alliance (AP) wanted minimum decentralization; the Spanish Socialist Workers' Party (PSOE) was sympathetic to a federal system.
