Women market workers in Lagos, an area in western Nigeria, in the 1920s were organized into a powerful group known as the Lagos Market Women Association (LMWA). In 1932, a rumor emerged that the British colonial government was going to begin taxing Lagosian women, which had never been done before, although taxes for men had been introduced in 1927 (in spite of coordinated resistance by different groups). The market women felt that a tax was unfair and that they were already struggling to make a living.
In 1956, Shell British Petroleum (now Royal Dutch Shell) discovered oil in what was then the British colony of Nigeria, and by 1958 commercial production had begun. Today, Nigeria has the tenth largest proven oil reserves in the world, is the tenth largest oil producer, and is the eighth largest oil exporter; yet nearly two-thirds of Nigerians live on less than $1.25 a day, 70% live below the national poverty line, and 83% live on less than $2 a day (each of those measurements place Nigeria in the bottom ten out of countries for which data is available).
