"It is quite difficult to define when the history of regionalism begins, since there is no single explanation that encompasses the origins and development of the regional idea. Criteria such as the desire by states to "make the best of their regional environment" are regarded by certain analystas as elusive; they prefer to consider the history of regionalism in terms of the rise of modern institutions.
