Cambio en el sistema de partidos post-autoritario: un proceso impulsado desde

This article explores those factors that produce change in the party-system, making use of theories concerning social cleavage and political agency that consider political repression and elite dynamics as independent variables. The authors examine three cases of authoritarianism in Latin America, Argentina, Brasil and Chile, to determine whether or not regime change is produced from above (via political elites) or below (via society).
