MotivationSomali women's political progress has been slow. The nation's patriarchal clan traditions perpetuate gender discrimination, bestowing an absolute priority upon all men for public affairs, whereas clan women remain voiceless, voteless, and restricted to private (household) affairs.PurposeTo better understand why, despite the minimal formal constraints on women's participation in political life, informal institutions and customs determine the social, economic, and cultural constraints on women such that they are often poorly equipped and/or reluctant to engage in public political activity.Methods and approachBased on secondary literature, the article seeks to explain how the influences of the clan patriarchal system exert a negative impact on Somali women's political participation. It identifies four structural categories—cultural, social, economic, and political—by which patriarchy has persistently impeded Somali women's participation in the nation's politics.FindingsAlthough women have contested the patriarchal system in Somalia through their participation in public decision‐making processes in different sectors and their involvement in politics, including an increasingly higher level of education, and more participation in the labour force, their numbers are still insufficient compared to men's.Policy implicationsGiven that patriarchy has been identified worldwide as one of the prime obstacles to women's participation in political and socioeconomic processes, there is a need for official quotas for women's representation in politics to balance severe gender inequalities, achieve women's full realization of human rights, and influence the issues raised and how political policies are shaped. There is also a need for women's political representation to imprint their competence as decision‐makers. The article sets out recommendations for tackling the four main structural barriers to achieving this, so that women can contribute fully to the development of Somalia, on a par with men.
