Umuofia can be seen as a microcosm of Nigerian society, an archetypal village
Okonkwo is a wealthy and respected warrior of the Umuofia clan, a lower Nigerian tribe that is part of a consortium of nine connected villages
In a settlement with a neighboring tribe, Umuofia wins a fifteen-year-old boy. Okonkwo takes charge of the boy, Ikemefuna, and finds an ideal son in him
"The Oracles said that Ikemefuna should be killed because he called you father" said by Ogbuefi Ezeudu
After several hours of walking, some of Okonkwo’s clansmen attack the boy with machetes. Ikemefuna runs to Okonkwo for help. But Okonkwo, who doesn’t wish to look weak in front of his fellow tribesmen, cuts the boy down despite the Oracle’s admonishment.
Okonkwo sinks into a depression, neither able to sleep nor eat. He visits his friend Obierika and begins to feel revived a bit. Okonkwo’s daughter Ezinma falls ill, but she recovers after Okonkwo gathers leaves for her medicine.
The death of Ogbuefi Ezeudu is announced to the surrounding villages by means of the ekwe, a musical instrument. Okonkwo feels guilty because the last time Ezeudu visited him was to warn him against taking part in Ikemefuna’s death. At Ogbuefi Ezeudu’s large and elaborate funeral, the men beat drums and fire their guns. Tragedy compounds upon itself when Okonkwo’s gun explodes and kills Ogbuefi Ezeudu’s sixteen-year-old son. Because killing a clansman is a crime against the earth goddess, Okonkwo must take his family into exile for seven years in order to atone. He gathers his most valuable belongings and takes his family to his mother’s natal village, Mbanta. The men from Ogbuefi Ezeudu’s quarter burn Okonkwo’s buildings and kill his animals to cleanse the village of his sin.
