This original study examines a vital but neglected aspect of the 1952 National Revolution in Bolivia; the activism of urban inhabitants. Many of these activists were Aymara-speaking people of indigenous origin who transformed the urban environment, politics and place of " " and "neighbors" within the city of La Paz. Luis Sierra traces how these urban residents faced racial discrimination and marginalization despite their political support for the Movimiento Nacionalista Revolucionario (MNR). reassesses the contingent, relational nature of Bolivia's racial categories and the artificial division between urban and rural activists.
