Yes Malcolm X's position on violence helped to make Martin Luther King's effort to become successful.
Step-by-step explanation:
Both Malcolm and Martin king were considered as the best political activists by the African Americans.
They both had completely different vision but had the same aim to fight for the rights of African Americans.
Malcolm preferred violence where Martin preferred non violence. Though Malcolm was not interested in Martin's non violence way of approach, he always respected him fellow leader who fights for the same cause.
When Malcolm was shot dead on February 21, 1965,Martin expressed his condolence and made him realize that Malcolm way of approach might also work and thus helped him to fight further.
