Hajiya Ma'daki

Salamatu Binin Abbas (1907–), better known by her title Hajiya Ma'daki, was a Nigerian noblewoman and influential advisor in the royal courts of Katsina and Kano. The daughter of Emir Muhammad Abbas of Kano, she was married at a young age to Emir Muhammadu Dikko of Katsina. In Katsina, she became a trusted advisor and confidant to the Emir. She also served as an unofficial ambassador, regularly engaging with influential figures in Britain and colonial Nigeria, including Flora Shaw, Clementine Churchill, and Princess Elizabeth, often advocating for the advancement of girls' education in Northern Nigeria.

After the death of Emir Dikko in 1944, Ma'daki returned to the Kano palace, where her senior brother, Emir Abdullahi Bayero, regularly sought her counsel. She later accepted a colonial government request to serve as matron at a girls' secondary school in Kano. She continued to use her influence with both prominent Nigerians and Europeans to shape policy in Northern Nigeria. While her influence on Dikko's decisions is not formally documented like those of men, it is likely that her opinion, like those of other women of the period, was a more significant factor in the development of Northern Nigeria during the colonial period than has been acknowledged.
