 After the death of Vladimir Lenin in 1924, Marxism–Leninism became a distinct philosophical movement in the Soviet Union when Stalin and his supporters gained control of the Soviet party.It rejected the common notions among Western Marxists at the time of world revolution as a prerequisite for building socialism in favour of the concept of socialism in one country.According to its supporters, the gradual transition from capitalism to socialism was signified with the introduction of the first five-year plan and the 1936 Soviet Constitution.
