Final answer:
Reconstruction policies led to the enfranchisement of African Americans and their participation in politics, resulting in the election of black politicians. Opposition from white Democrats led to discrimination through segregation and voter suppression.
Step-by-step explanation:
The results of Reconstruction policies and practices shaped the politics of the reconstructed states and the nation at large in several ways. First, Reconstruction policies led to the enfranchisement of African Americans and their participation in politics. This resulted in the election of black politicians at the national, state, and local levels during Reconstruction. However, the efforts to establish political and social equality faced opposition from white Democrats who sought to regain control and subjected African Americans to discrimination through segregation and voter suppression.
