Within the enormous territorial expanse which now constitutes the Argentine Republic political integration was effected slowly. The different populations settled at intervals along the routes which connected Buenos Ayres with Lima on the one side, with the Andes on another and with Asuncion on still another. Each settlement was an oasis of Spanish population set in the midst of a savage country. In order to establish something approaching unity within each section, the people organized themselves after the pattern of the urban centers of Spain with their _Cabildo_ or town council as the communal authority, which controlled and regulated the extremes of opinion and conditions and brought the whole municipal life to a focus. Each settlement lived a life apart, separated from the others. In fact they were cast in the mold of the ancient Spanish village society, and the central authority only made itself felt at infrequent intervals. The inhabitants of each village thus developed an aptitude for municipal life and for self-government, and a concentration upon local interests which became the basis of their political development. They fostered a local character which was the very foundation and essence of their later federal tendency. To the interests and pretensions of the crown as formulated by the "Council of the Indies," they preferred the authority of the viceroy and of the intendants, but their main preference was the municipality itself, whose frank and loyal mouthpiece was the traditional Cabildo. For this reason, when the movement for independence commenced, each village and each city was led by its own Cabildo, and it was the Cabildo which gave vigor and form to the revolution. Around the Cabildo the inhabitants of the vicinity grouped themselves in the different organic or anarchic revolts which followed. It was for this reason, too, since the present republic possessed no basis of political division, that each one of the cities formed a nucleus in its respective province of the same name, and that the whole territory was subdivided according to the radius of authority exercised by the principal cities of colonial times, without any account being taken of economic autonomy or of demography.
