 Colonial rule transformed Igbo society , as portrayed in Chinua Achebe 's novel Things Fall Apart . British rule brought about changes in culture , such as the introduction of Warrant Chiefs as Eze ( indigenous rulers ) where there were no such monarchies . Christian missionaries introduced aspects of European ideology into Igbo society and culture , sometimes shunning parts of the culture . The rumours that the Igbo women were being assessed for taxation sparked off the 1929 Igbo Women 's War in Aba ( also known as the 1929 Aba Riots ) , a massive revolt of women never encountered before in Igbo history .
