Formed in 1923 by Herbert Macaulay to take advantage of the new Clifford Constitution, which succeeded the 1914 Nigerian Council. The NNDP successfully organized various Lagos interest groups into a single group that was able to compete politically. The (NNDP) ran many candidates for seats in the 1922 elections for the Lagos Legislative Council, winning three seats. The party won all the seats in the elections of 1923, 1928 and 1933. Though, the party's major function was to put candidates into the legislative council, it had a broader objective of promoting democracy in Nigeria, increasing higher Nigerian participation in the social, economic and educational development of Nigeria. The party continued to dominate politics in Lagos until 1938, when the Nigerian Youth Movement (NYM) overtook it in elections.
