A A conceptual approach to military history and frontiers: the Chaco War and the Leticia Issue

Abstract

The present article aims to address the different conceptions of the border between States and its political and military developments in the 20th and 21st centuries. The theoretical approach, however, dates back to the 19th century, where literary works provided insights into the history and geopolitics that guided the political decisions of rulers, especially in the first half of the twentieth century, where the Chaco War and the Leticia Question will be the our research target. The article also emphasizes that, in addition to the conflicts in parallel to the Brazilian border, there were political tensions established between Brazil and its neighbors due to the traditional rivalry and the dispute for control of regional power. The investigation, based on the current theoretical arguments, also helped to demonstrate that the Brazilian military of the period were the main responsible for the intervention of the North and the Brazilian Midwest considering, for this purpose, the territorial occupation and the control of the terrestrial limits , for the maintenance of national sovereignty.
