In this master's thesis, a hermeneutic analysis of the work Dias y Noches de Amor y de Guerra by Eduardo Galeano is presented facing the messages contained on the sociopolitical and cultural processes experienced during the Uruguayan dictatorship (1973-1985), which emerged in the midst of the violence of the regimes imposed in Latin America during the second half of the 20th century in the framework of Operation Condor. The foregoing enables us to see how political positions, messages of denunciation and disclosure are transmitted in literary language against the established systems through systematic repression, abuse of power and violations of Human Rights.
