This introduction assesses the effects of Latin America’s pink tide on gender equality in the region. We find that left governments and left competition provide an opportunity for advancing gender equality. However, the dominant pattern during Latin America’s pink tide was one of a reactive left. Pink tide governments typically did not have clearly articulated gender equality initiatives on their immediate policy agendas. Instead, left governments mostly reacted to pressures from domestic gender equality activists. In addition to left ideology and feminist mobilization, left party type and policy type explain progress and setbacks in gender equality across six outcome areas.
