A tricycle driver rides past a graffiti at the entrance to the old city in Zaria, Nigeria, July 17, 2014. The Emirate of Kano is part of the Sokoto Caliphate, one of the great Islamic empires that dotted the Sahel, profiting from caravan routes connecting Africa's interior with its Mediterranean coast. Nigeria's former colonial ruler Britain kept most of the northern hierarchy in place and the emirate continued to hold sway over the largely underdeveloped region after independence in 1960. Lamido Sanusi, Nigeria's ousted central bank governor, was named Emir of Kano in June, making an outspoken government critic one of the most influential leaders in the largely Muslim north. The throne, however, has few constitutional powers. Picture taken July 17, 2014. REUTERS/Joe Penney (NIGERIA - Tags: RELIGION ROYALS SOCIETY)
