Northern Nigeria (Hausa: Arewacin Najeriya) was a British protectorate which lasted from 1900 until 1914 and covered the northern part of what is now Nigeria. The protectorate spanned and included the emirates of the Sokoto Caliphate and parts of the former Bornu Empire, conquered in 1902. The first High Commissioner of the protectorate was Frederick Lugard, who suppressed slavery and tribal raiding and created a system of administration built around native authorities. The Protectorate was ended on 1 January 1914, when its area was unified with the Southern Nigeria Protectorate and the Lagos Colony, becoming the Northern Province of the Colony and Protectorate of Nigeria. Foundation The Berlin Conference of 1884 and 1885 provided the area that would become the Northern Nigeria Protectorate to the British. The Royal Niger Company was formed in 1886 with George Taubman Goldie as the vice governor. The Company moved in-land and negotiated trade agreements and political agreements, sometimes coercive, with several local chieftains. In 1897, Frederick Lugard was the appointed head of the West African Frontier Force which was tasked with stopping Fulani resistance and possible French incursions in the northwest area. On 1 January 1900, the Royal Niger Company's charter was revoked and the British government took control, in a ceremony where Lugard read the proclamation. The Royal Niger Company was paid £865,000 and was given the rights to half of all mining revenue in a large part of the areas for 99 years in exchange for ceding the territory to the British government. Lugard was appointed the High Commissioner of the newly created Northern Nigeria Protectorate. Lokoja was the capital from 1900, but Zungeru became the headquarters for the protectorate in 1902 because it was the most northerly city accessible by river transport. Military campaign Military operations began in 1902 and continued for about five years of sporadic fighting. The remnants of the Bornu Empire were conquered in 1902 and the Sokoto Caliphate and was defeated in the Battle of Kano. Fighting continued in 1904 in Bassa.In 1906, a Mahdist rebellion broke out outside the city of Sokoto in the village of Satiru. Elements of the Royal West African Frontier Force were dispatched to suppress the rebellion; upon hearing news of what had transpired, Muhammadu Attahiru II dispatched a mixed force of 300 Sokoto cavalry and infantry led by Mallam Isa to join them. The combined force successfully suppressed the rebellion, which
