The Hausa system of government and taxation was adopted by the Fula when in the early part of the 19th century that Mahommedan people overran the Hausa states.
It has been erroneously stated that the Fula imposed Mahommedanism on the Hausa states.
The palace of the emir, in front of which is a large open space, is in the Fula quarter in the south-east of the city.
The Fula form the aristocratic class.
Barth, however, concluded that the present town does not date earlier than the second half of the 1 6th century, and that before the rise of the Fula power (c. 1800) scarcely any great Arab merchant ever visited Kano.
