Meanwhile Argentina, the great neighbor of Brazil to the southwest, had been gaining territory and new resources. Since the definite adoption of a federal constitution in 1853, this state had attained to a considerable degree of national consciousness under the leadership of able presidents such as Bartolome Mitre, the soldier and historian, and Domingo Faustino Sarmiento, the publicist and promoter of popular education. One evidence of this new nationalism was a widespread belief in the necessity of territorial expansion. Knowing that Chile entertained designs upon Patagonia, the Argentine Government forestalled any action by conducting a war of practical extermination against the Indian tribes of that region and by adding it to the national domain. The so-called "conquest of the desert" in the far south of the continent opened to civilization a vast habitable area of untold economic possibilities. In the electoral campaign of 1880 the presidential candidates were Julio Argentino Roca and the Governor of the province of Buenos Aires. The former, an able officer skilled in both arms and politics, had on his side the advantage of a reputation won in the struggle with the Patagonian Indians, the approval of the national Government, and the support of most of the provinces. Feeling certain of defeat at the polls, the partisans of the latter candidate resorted to the timeworn expedient of a revolt. Though the uprising lasted but twenty days, the diplomatic corps at the capital proffered its mediation between the contestants, in order to avoid any further bloodshed. The result was that the fractious Governor withdrew his candidacy and a radical change was effected in the relations of Buenos Aires, city and province, to the country at large. The city, together with its environs, was converted into a federal district and became solely and distinctively the national capital. Its public buildings, railways, and telegraph service, as well as the provincial debt, were taken over by the general Government. The seat of provincial authority was transferred to the village of Ensenada, which thereupon was rechristened La Plata.
