Mary Mitchell Slessor was a Scottish Presbyterian missionary who dedicated her life to serving the Efik and Okoyong people in Nigeria. Born in Aberdeen in 1848, she grew up in a working-class family in Dundee before traveling to West Africa in 1876. After mastering the Efik language, she lived among local communities, often in remote areas, to provide education and religious instruction. She is widely recognized for her humanitarian efforts, particularly her work protecting children and advocating for women's rights in the Calabar region.
Missionary work


Slessor worked extensively in the Calabar region, where she gained the trust of the local population through her linguistic skills and pragmatic nature. She was instrumental in establishing the Hope Waddell Training Institute to provide vocational education. Beyond religious teaching, she acted as a mediator in local disputes and served as a vice-consul in Okoyong, where she presided over native courts.
Humanitarian legacy

She is most noted for intervening to stop the practice of infanticide involving twins, which was a common belief in certain areas. Slessor rescued numerous abandoned infants, often adopting them herself. Her efforts to replace traditional customs, such as using poison to determine guilt, with different social practices helped shape the community. In Britain, her courageous work earned her the nickname "the white queen of Okoyong."
