Brackenbury, A Short Vocabulary of the Fulani Language (Zungeru, 1907); the articles Nigeria and Sokoto and authorities there cited.
The rioters were predominantly from the Hausa Fulani tribe, which is not indigenous to the area.
In the first instance, as following upon conquest or potential conquest, the Fulani emirs who were appointed by government to each of the great native states were installed under a letter of appointment in which (in addition to rights of legislation, taxation and other powers inherent in suzerainty) the ultimate title to all land was transferred from the Fulani dynasty and vested in the British.
When these conditions were accepted by the Fulani chiefs the supremacy of Great Britain was established over the entire country.
These conditions were that all rights of conquest acquired by the Fulani throughout Northern Nigeria passed to Great Britain, that for the future every sultan and emir and principal officer of state should be appointed by Great Britain, that the emirs and chiefs so appointed should obey the laws of the British government, that they should no longer buy and sell slaves, nor enslave people, that they should import no firearms, except flint-locks, that they should enforce no sentences in their courts of law which were contrary to humanity, and that the British government should in future hold rights in land and taxation.
