The Treaty of La Paz, signed on March 14th 1935, by the alliance nations with Bolivia. Bolivia is forced to renounce to their claims to the Chaco region and accept Paraguay's control of the area. Brazil moves the border into San Pablo River in the Bolivian province of Santa Cruz while Chile gains small territorial concesions in the provinces of Potosi, Oruro and La Paz. Basically the nation of Bolivia lost half of their territorial integrity.
