The Role of Electoral Coordination in Party Formation: Explaining the Origin of the Uruguayan Frente Amplio in 1971

Abstract What is the origin of the Frente Amplio? While most contributions focus on party-building strategies and the electoral success of the Left, scholars have overlooked the previous process of party formation. This paper studies the Frente Amplio's formation in 1971 as a case of complete electoral coordination between extant parties, factions and individual left-wing politicians who understood the electoral inefficiencies of competing with each other. Making use of a historical narrative, our account complements other approaches, suggesting the critical role of electoral coordination, favoured by two systemic conditions (electoral stability and programmatic politics) that eased the process of party formation.
