Concept:The Nigerian Youth Movement (NYM) started under an earlier name before expanding to a national body.
Explanation:The movement was originally founded in Lagos in 1934 by young nationalists such as Ernest Ikoli, H.O. Davies, Dr. J.C. Vaughan, and Samuel Akinsanya.
At that time, it was called the Lagos Youth Movement (LYM).
In 1936, its membership grew to include Nigerians from other regions.
Because of this wider membership, the group changed its name to the Nigerian Youth Movement (NYM).
Thus, the NYM directly evolved from the LYM.
