Gagoangwe (circa 1845–1924) was the mohumagadi (meaning queen or queen-mother) of the Mmanaana Kgatla and later the BaNgwaketse, subgroups of the BaTswana in what is now Botswana.[1][2] When she was young, she put out the eye of a servant, and her father allowed the servant to put out one of her eyes in return.[2] Therefore she was known as the "one-eyed Queen".[3] She married Kgosi Pulane, but in 1875 she eloped with and Bathoen I, who was heir to the leadership of the BaNgwaketse.[2] In 1890 she married Bathoen I in a Christian marriage ceremony.[4] She was a Christian and impacted Bathoen I's support of the London Missionary Society.[2] In 1910 Bathoen I died and Gagoangwe's older son became the king, but he was killed by his own brother in 1916.[2] Following this, Gagoangwe had her murderous son assassinated, and obtained control of the regency herself in 1923.[2] She worked on the development projects of the son who had been murdered, and secured the regency for her daughter Ntebogang Ratshosa before her own death.[2]
