The expansion of organized labor that occurred during the 1920s was met with multiple government reprisals and was largely curbed by the Chaco War with Paraguay of 1932-1935. Nevertheless, despite being compelled to operate illegally, the labor movement found support in several political parties, the most successful of which was the Movimiento Nacionalista Revolucionario, a powerhouse in the miners' federation. Conscious of the remarkable upheavals which punctuated Bolivian history during the twentieth century, Alexander traces the relative successes of Bolivia's labor unions, contextualizing their triumphs and disappointments within the captivating history of Bolivia's tumultuous political scene.Bolivia was the center stage for one of the most important Latin American social revolutions of the twentieth century, one that occurred amid a sea of tremendous political instability.
