When the Cape's political system was severely weakened, the movement survived as an increasingly liberal, local opposition against the Apartheid government of the National Party. In the fight against Apartheid, African majority took the lead in the struggle, as effective allies the remaining Cape liberals against the growing National Party, engaged to a degree in collaboration and exchange of ideas with the growing African liberation movements, especially in the early years of the struggle. This is seen through the non-racial values that were successfully propagated by the political ancestors of the African National Congress, and that came to reside at the centre of South Africa's post-Apartheid Constitution.
