The consequence has been, that most of the new states in their very infancy have been subjected to the embarrassing necessity of re-casting their governments, and dividing and subdividing their extensive territories, as the varying and distinct interests of their several component parts have shown to be requisite for their due protection and development. Nothing has tended more to retard the organization and improvement of their political institutions than this necessity; and nowhere has it been more strikingly exemplified than in the widely-spread provinces of La Plata. In the first years of the struggle with the mother country, one common object, paramount to all other considerations, the complete establishment of their political independence, bound them together--perhaps I should more correctly say, prevented their separation;--but the very circumstances of that struggle, and the vicissitudes of the war, which often for long periods together cut off their communications with the capital, and with each other; obliging them to provide separately for their own temporary government and security, gave rise in many of them, especially those at a distance, to habits of more or less independence, which, as they imperceptibly acquired strength, produced in some, as in Paraguay and Upper Peru, an entire separation from Buenos Ayres; and in others such an assumption of the management of their own provincial affairs, as ere long reduced the metropolitan government to a nullity. It is true that, up to 1820, the semblance of a Central Government was maintained at Buenos Ayres, but in that year the unpopularity of the measures of the Directory and of the National Congress led to its final dissolution, under circumstances which precluded all hope of its re-establishment, and terminated in the system of federalism, which has ever since _de facto_ subsisted. Experience has taught Buenos Ayres the inefficacy of forcible measures to bring back the provinces under her more immediate control; and though congresses have been more than once convoked for the purpose of establishing something more definite as to the form, at least, of their national government, whether central or federal, individual and local interests have always prevailed in thwarting such an arrangement; and the probability now is, that for a long time to come the national organization of this State will be limited to the slender bonds of voluntary confederation, which at present constitute the _soi-disant_ union of the provinces, not only with each other, but with their old metropolis, Buenos Ayres.
