Igbo
The Igbo-speaking people inhabit most of southeastern Nigeria. Their political economy and culture have been shaped by their long history of habitation in the forest region. Important themes relating to the Igbo past have centered on the question of origin, the agrarian bases of their economy, the decentralized and acephalous structure of their political organization, an achievement-based social system rooted in their traditional humane living, and a fluid gender ideology that recognized male and female roles as complementary rather than oppositional. The Igbo contributed to major historical developments including the development of agriculture, the Bantu migration, and its influence in the making of Bantu cultural areas in sub-Saharan Africa. On the global arena, the Igbo contributed significantly to the transformation of the New World through the Atlantic slave trade and the making of New World cultures. The Igbo made the transition to palm oil production in the postabolition era, thereby contributing to the industrialization of Europe as well as linking their society to the global capitalist economy from the 19th century. The Igbo encounter with Europeans continued through British colonialism, and their struggle to maintain their autonomy would shape British colonialism in Nigeria and beyond. The postcolonial era has been a time of crisis for the Igbo in Nigeria. They were involved in a civil war with Nigeria, known as the Nigeria-Biafra war, and experienced mass killing and genocide but continued to be resilient, drawing from their history and shared experience.
