I Sweat the Flavor of Tin

Labor Activism in Early Twentieth-Century Bolivia

In this important and finely wrought social history, Robert Smale explores the potent alchemy of worker activism and Socialist Party politics that periodically turned the tin mines of Oruro and northern Potos’ into battlegrounds of popular mobilization and state violence. Shifting the focus away from the recent emphasis on indigenous peasant movements, Smale locates the urban popular classes and their revolutionary unions at center stage of the larger narrative of Bolivia's turbulent political history leading up to the Chaco War.

On June 4, 1923, the Bolivian military turned a machine gun on striking miners in the northern Potosi town of Uncia. The incident is remembered as Bolivia’s first massacre of industrial workers. The violence in Uncia highlights a formative period in the development of a working class who would eventually challenge the oligarchic control of the nation.

Robert L. Smale begins his study as Bolivia’s mining industry transitioned from silver to tin; specifically focusing on the region of Oruro and northern Potosi. The miners were part of a heterogeneous urban class alongside artisans, small merchants, and other laborers. Artisan mutual aid societies provided miners their first organizational models and the guidance to emancipate themselves from the mine owners’ political tutelage. During the 1910s both the Workers’ Labor Federation and the Socialist Party appeared in Oruro to spur more aggressive political action. In 1920 miners won a comprehensive contract that exceeded labor legislation debated in Congress in the years that followed. Relations between the working class and the government deteriorated soon after, leading to the 1923 massacre in Uncia. Smale ends his study with the onset of the Great Depression and premonitions of war with Paraguay—twin cataclysms that would discredit the old oligarchic order and open new horizons to the labor movement.

This period’s developments marked the entry of workers and other marginalized groups into Bolivian politics and the acquisition of new freedoms and basic rights. These events prefigure the rise of Evo Morales—a union activist born in Oruro—in the early twenty-first century.
