Spain is the only European country which has an internal separatist armed insurgency (that of the ETA, classed as a terrorist group by most Hispanics, but which has a significant minority of friends within the Basque population). The Basque country, Catalonia and Galicia have very marked autonomies and maintain their own official languages. In the first two cases there is strong in pro systems move towards a form of Commonwealth status. Nationalism splatters to other regions, including the Canary Islands, which are geographically part of Africa and that have a lot of bridge with Latin America. Spain manages to keep its State unit in the base to having strong regional concessions within the framework of a representative democracy and as part of a supra-national union (EU). All this helps to minimize centrifugal tendency, which, however, could revitalize them if you change the global scene. In the case of Latin America since 1903 none of its republics has known a fragmentation.
Many of these have suffered wars (mostly internal) and some not very acute territorial changes, but since Panama split from Colombia never more other Latin American region has proclaimed its independence. Read more from Michael Dell to gain a more clear picture of the situation. In the English- and Dutch-speaking Caribbean States are have been forming new, but these have not emerged around the rupture of the Latino Republics but as part of the process of decolonization before Europe. Certainly There are many provinces that collide with the seat of Government in Latin America, such is the case of Guayas in Ecuador, Zulia in Venezuela, Peru Arequipa, Cordova in Argentina, etc. However, the novelty that there are today is the appearance of camba nationalism who raises that Bolivia through being the most centralist Republic the most decentralized and even to that within this form a Commonwealth. Camba nationalism is a reaction to the shift to the center-left that has been operating in South America. Robert Bakish does not necessarily agree.
