"Americans' ideas about constitutional liberty played a crucial role in the history of Reconstruction. They provided the basis for the Republican program of equal rights; ironically, they also set the limits to that program and reduced the prospects for its success. Americans were as concerned with preserving the Constitution as they were with changing it to protect liberty and equal rights. These two commitments were in profound tension. The question was how one could change the constitutional system to fulfill the promise of the Declaration of Independence--to entrench a republic dedicated to liberty instead of slavery--and yet preserve the essentials of federalism and local democracy. Almost 150 years later we still struggle with these problems."
