some igbo subgroups, such as the ikwerre, started dissociating themselves from the larger igbo population after the war. in the post-war era, people of eastern nigeria changed the names of both people and places to non-igbo-sounding words. for instance, the town of igbuzo was anglicized to "ibusa". due to discrimination, many igbo had trouble finding employment, and during the early 1970s, the igbo became one of the poorest ethnic groups in nigeria.
