The historiography on Uruguay during the Cold War has identified the period 1959–62 as a key juncture in the process of political polarisation that culminated in the fall of democracy in 1973. Based on the analysis of press articles and other documentary sources, I describe the role played by the main fraction of the Partido Colorado (Red Party) led by Luis Batlle Berres in promoting polarisation of the Uruguayan political system in those years. My findings contradict the conventional depiction of Batlle Berres as a moderate who tried to prevent the polarisation provoked by other agents.
