Estado y política agraria en la frontera sur argentina: el territorio nacional de Río Negro (1916-1930)

the president hipólito yrigoyen, leader of the radical civic union party (1916-1930), took office in 1916. he promoted a policy which supposedly pretended to rectify the previous "conservative order". the implementation of such policy in the national territories -real internal borders of the national state- was easier due to the administrative and political centralization of those territories, resulting in an appropriate perspective to interpreter the state's conduct as well as its interests and motivations. in this article we intended to analyze the state-territories relation through a case study: the national territory of río negro, a very old inhabited place on the south border, in the north of the patagonia, which since its establishment needed the state's decision to get through the determining factors for the agricultural development. nevertheless, the radical government would not get away from the prevailing agricultural policy and would show difficulties in overcoming certain obstacles, related to the navigability of the river negro and its periodic floods, destructive of any sustainable farming progress.
