This paper investigates the extent to which the Universal Declaration of Human Rights (UDHR) and the Convention on the Elimination of All Forms of Discrimination Against Women (CEDAW) have succeeded in enhancing women’s citizenship in Kenya. The paper is particularly concerned with how women in Kenya have used the rights enshrined in the two instruments to claim entitlements and to challenge various forms of discrimination at individual and collective level. The paper is divided into three parts. The first part outlines the nexus between globalization and the emergence of international instruments concerning women’s rights and freedoms. The second part examines the development of UDHR and CEDAW and the extent to which government and civil society organizations have appropriated these international instruments to agitate for gender friendly legislation. The paper puts emphasis on the Kenyan Constitution and the gender advocacy for its review, Sexual Offences Act, and Women’s Property Rights. The last part looks at challenges and opportunities in the application of international instruments to increase women’s citizenship. The paper relies on the rigorous corroboration of available secondary data together with CEDAW Committee reports and CEDAW Shadow reports produced by the various governmental and nongovernmental organizations.
