Nri influenced the constitution of the Benin Oba's status. Differing points of view are focused particularly on the communities of Asaba, Onitsha, and Oguta. According to some scholars who argue against what is known as the Afigbo and Omenka Thesis on Origin, Igbo kings of these places trace the historical roots of their investiture immediately to the Oba of Benin. They tend to be called Obi as royal title of honour. The third source of Igbo kingship is believed to be 19th and 20th century colonial rule by the British. Under a policy of indirect rule, the colonial administration created "warrant chiefs," selecting recognised individuals to serve as administrators, rulers, judges and tax collectors. Native to their communities, warrant chiefs were usually selected from among those men who were most cooperative with the colonial administration. For this and a number of other reasons, Igbo populations often resented and sometimes overtly resisted the authority of warrant chiefs. An example of such resistance is the Igbo Women's War of 1929. After Nigeria gained its constitutional independence from Britain on Saturday 1 October 1960, many of those warrant chiefs tried to maintain their power by seeking to recast their political roles. Those with political influence and new-found wealth bought honorary Eze- sounding titles. They clamored to be among traditional rulers retained by government of independent Nigeria. Notes 1.
