John Madaki

John Yahaya Madaki (?–2018) was military governor of Katsina State, Nigeria in December 1989, during the military regime of General Ibrahim Babangida. He handed over to the elected civilian governor Saidu Barda in January 1992 at the start of the Nigerian Third Republic.

Early years
Madaki was born in Gawu Babangida in Gurara local government, Niger State. He was nicknamed "jungle expert" after attending a course in Malaya on Advanced Jungle Warfare and Combat Survival. At the time of the 1985 coup in which General Ibrahim Babangida came to power, Major John Madaki was commanding officer of the 123 Guards Battalion at Ikeja, and assisted in the success of the coup.

Katsina Governor
Madaki was promoted to Lt. Colonel and became governor of Katsina State in December 1989. Katsina was the center of the Islamic Movement that had been established in 1985 with the goal of establishing an Islamic state in Nigeria. In May 1990, Madaki warned all religious leaders to stay out of politics, and established a religious board to license and control the activities of all Islamic preachers in the state. Tensions rose, and after rioting many of the Islamist leaders were arrested. After handing over to the civilian governor in January 1992, Madaki returned for two more tours of duty as Commander, Brigade of Guards before retiring as a Colonel.
