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.
The Ogoni region is a highly oil-rich area in the Niger Delta area of Nigeria, populated by approximately 500,000 members of the Ogoni People. Since the Shell Petroleum Development Company discovered oil in Ogoniland in 1958, the region has been plagued with serious environmental degradation resulting from the over 100 oil wells in the area.
