Before the British constructed military post in 1901, Aba was a traditional market town. In 1915, a railway from Port Harcourt was built, and the town began to collect local agricultural goods, notably palm oil. It was also the site of the Women's Riot against taxes, in which thousands of Igbo women threatened war against the British colonists. Since then, it has grown to be the center of art, science, and technology in the area.
