Freedom, Union, and Power analyzes the beliefs of the Republican Party during the Civil War, how those beliefs changed, and what those changes foreshadowed for the future. With Lincoln's election, Republicans faced something new: responsibility for the government. With responsibility came the need to wage war for the survival of that government, the country, and the party. And with victory in the war came responsibility for saving the Union by ending slavery - and for pursuing policies that fit their belief in a strong, free Union. Michael Green shows how Republicans wielded federal power to stop a rebellion while maintaining their hold on that power - the intersection of policy and politics.
