These same financial and administrative challenges resulted in discussions led by Lugard for the unification of the Lagos Colony, the Southern Nigeria Protectorate, and Northern Nigeria. The disparities between the protectorates was to be corrected by creating a central administration in Lagos, with custom revenues from the south paying for the projects in the north. The unified Colony and Protectorate of Nigeria began in 1914 and had two lieutenant governors with one responsible for the area of the southern province and another responsible for the northern province. The administration in the north remained largely separate and included and deepened the use of native authorities. These divisions have been found to persist in many respects to this day.
