Marchar y militar: vínculos sociales en el Frente Amplio chileno en contexto latinoamericano (2017-2023).

This article aims to explain why the Chilean Frente Amplio has not managed to consolidate stable links with the main social movements in the country despite having emerged in a context of social mobilization. Secondly, it aims to contextualize the case of the Frente Amplio in the Latin American scenario through paradigmatic cases of parties that have managed to develop and maintain links with social organizations. The article addresses four possible explanations: the autonomous and non-partisan nature of social mobilization, the rapid and costly access of the coalition to the institutional apparatus, the consolidation of an organizational structure less open to the influence of social organizations and, transversally, the disposition adopted by the coalition at key moments of its trajectory towards organized civil society. The article concludes by highlighting the importance of both contextual factors and explanations associated with party agency. [ABSTRACT FROM AUTHOR]
