Woman in twentieth century colonial Africa experienced a loss of power in their social-economic status. The Women Went Radical provides a narrative of radical expressions extracted from the numerous petitions written to advance and advocate the cause of Yoruba women through individual and collective action. This analyses the impact and implication of petition writing on the administration of traditional and modern governments in colonial Yorubaland. The political context accurately projects the roles of women in influencing, resisting, negotiating and counteracting policies within the political system. The research argues that petition writing is a form of politics and radicalism that is not limited to national issues but also to their manifestation from the actions of the citizens—that is ‘politics from the grassroots’.
