After Nigeria’s independence from Britain in 1960, Obi was elected a legislator in the Eastern House of Assembly in 1960, he refused to vacate his seat in the national legislature in Lagos, the Speaker of the regional house ordered that Obi be physically removed by security agents. This order was obeyed and Obi decided to commit himself to regional affairs.
In 1962, Obi was arrested and charged with treason in a shadowy trial organized by the then national civilian government, who accused him and others, including the main opposition leader at the time, Obafemi Awolowo, of plotting to overthrow the government. He was later released for lack of evidence.
When the Civil War broke out in 1966, Obi pitched his tent with the Biafran side, working for the rebel leader Odemegwu Ojukwu.
After the war, he returned to lecture in 1970 at the University of Lagos where he quickly rose to the senior academic role of a professor. But for a brief period in the 1970s when he served in the National Revenue Mobilization Commission, he was a university teacher until his retirement as a an Emeritus Professor in 1985.
He left Lagos to return to his root in the city of Onitsha, establishing the Nanna Institute for Scientific Studies. In 1997, it was from the institute that he worked unaided with modern technologies to solve the four-century old mathematical puzzle.
