From the remote Patagonia to the north of Mexico, the first republican generation led the war of independence against Spain and, between the years 1810 and 1830, took part in the political and constitutional creation of the new States. This first republican movement, seen as an intellectual and political movement, remained in the dominant forefront until 1848, when changes begin occurring within the new countries as well as in their relations with the United States and Europe. The outcome of this period of conflict was marked by the disenchantment born from the tension between the Utopian ideals of the first republicans and a complex cultural reality, social disparity and the Caudillos that arose from these revolutionary exploits, and its effects are still felt in the first decade of the twenty first century. - Publisher.
