There are four reasons that explain why countries have implemented gender quotas: to increase female representation, an advantageous strategy used by the political elite, gender quotas mean equality and representation which is an emerging notion, and gender quotas have become an international norm and adopted through 'transnational sharing'. This article focuses on the fourth point and combines empirical work on gender quotas with insights from the international norms literature to identify distinct international and transnational influences. The findings determine that influences are only clear when analysing quota campaigns as a global phenomenon.
