The following work is focused on knowing the militant practices of the socialists in the municipality of Morón, province of Buenos Aires, between the years 1917 - 1922. For this, a qualitative analysis of the editorials of two newspapers, of the newspaper La Vanguardia, has been carried out, official organ of the Socialist Party of Argentina, and of the newspaper El Imparcial, a local newspaper published between 1914 and 1950 ideologically identified with conservative sectors. The proposed theme is highly relevant, since from this it is possible to analyze how the socialist citizens of Morón acted and intervened in their local reality. The selected period responds to a context of great class and interclass conflict, influenced by different national and international processes, such as the Bolshevik Revolution, which configured a particular scenario of great activity by the labor movement and elites throughout the world. In the following work it is argued that the activism of the Socialist Party in Morón between 1917 - 1922 was based on the visibility of local problems and party propaganda in electoral periods, implemented through the different socialist centers of the municipality. The results show the existence of a militant practice in the Morón community that leaned towards socialism with different degrees of activity, influenced by the electoral periods, whose objectives were to weaken support for the opposition political sectors of the population.
