Explanation:

Radical Reconstruction is the strategy or motion that was passed by the United States Congress around 1867, to ensure amongst other things, that the civil rights of the freedmen and coloured people were guaranteed comprehensively.

On the other hand, Jim Crow's Laws were laws specially made to eliminate political and economic advantages that were being enjoyed by the black people during the Reconstruction period

However, in the attempt of the Southern States to limit the effects of Radical Reconstruction, they enacted Jim Crow's law.
