The Aba women riot of 1929

The Women's War, or Aba Women's Riots, was a period of unrest in British Nigeria over November 1929. It was the first major anti-colonial revolt by women in West African.

The Aba Women's War was sparked by a dispute between a woman named Nwanyeruwa and a man, Mark Emereuwa, who was helping to make a census of the people living in the town controlled by the Warrant, Okugo. Nwanyeruwa was of Ngwa ancestry, and had been married in the town of Oloko. In Oloko, the census was related to taxation, and women in the area were worried about who would tax them, especially during the period of hyperinflation in the late 1920s. The financial crash of 1929 impeded women's ability to trade and produce so they sought assurance from the colonial government that they would not to be required to pay taxes. Faced with a political halt, the women settled that they would not pay taxes nor have their property appraised.

On the morning of November 18, Emereuwa arrived at Nwanyereuwa's house and approached Nwanyereuwa, since her husband Ojim, had already died. He told the widow to "count her goats, sheep and people." Since Nwanyereuwa understood this to mean, "How many of these things do you have so we can tax you based on them", she was angry. She replied by saying "Was your widowed mother counted?," meaning "that women don't pay tax in traditional Igbo society." The two exchanged angry words, and Emeruwa grabbed Nwanyeruwa by the throat. Nwanyeruwa went to the town square to discuss the incident with other women who happened to be holding a meeting to discuss the issue of taxing women. Believing they would be taxed, based on Nwanyeruwa's account, the Oloko women invited other women (by sending leaves of palm-oil trees) from other areas in the Bende District, as well as from Umuahia and Ngwa. They gathered nearly 10,000 women who protested at the office of Warrant Chief Okugo, demanding his resignation and calling for a trial.
