HISTORY: My Great-Grandfather, the Nigerian Slave-Trader.

Down the hill, near the river, in an area now overrun by bush, is the grave of my most celebrated ancestor: my great-grandfather Nwaubani Ogogo Oriaku. Nwaubani Ogogo was a slave trader who gained power and wealth by selling other Africans across the Atlantic. “He was a renowned trader,” my father told me proudly. “He dealt in palm produce and human beings.”

Long before Europeans arrived, Igbos enslaved other Igbos as punishment for crimes, for the payment of debts, and as prisoners of war. The practice differed from slavery in the Americas: slaves were permitted to move freely in their communities and to own property, but they were also sometimes sacrificed in religious ceremonies or buried alive with their masters to serve them in the next life. When the transatlantic trade began, in the fifteenth century, the demand for slaves spiked. Igbo traders began kidnapping people from distant villages. Sometimes a family would sell off a disgraced relative, a practice that Ijoma Okoro, a professor of Igbo history at the University of Nigeria, Nsukka, likens to the shipping of British convicts to the penal colonies in Australia: “People would say, ‘Let them go. I don’t want to see them again.’ ” Between the fifteenth and nineteenth centuries, nearly one and a half million Igbo slaves were sent across the Middle Passage. . . .

Nwaubani Ogogo was so esteemed that, when he died, a leopard was killed, and six slaves were buried alive with him. My family inherited his canvas shoes, which he wore at a time when few Nigerians owned footwear, and the chains of his slaves, which were so heavy that, as a child, my father could hardly lift them. Throughout my upbringing, my relatives gleefully recounted Nwaubani Ogogo’s exploits. When I was about eight, my father took me to see the row of ugba trees where Nwaubani Ogogo kept his slaves chained up. In the nineteen-sixties, a family friend who taught history at a university in the U.K. saw Nwaubani Ogogo’s name mentioned in a textbook about the slave trade. Even my cousins who lived abroad learned that we had made it into the history books.

Interesting reading. I remember that Zora Neale Hurston’s Barracoon couldn’t find a publisher because it focused too much on the African role in the slave trade. Now Africans are talking about it themselves.
