Bruce Levine [...] restores [Stevens] fully to his place in the American pantheon with [...] a concise and powerful biography. With a firm grasp on the era’s political history, Mr. Levine pilots us deftly through Stevens’s rise in the Whig Party, his early participation in the antislavery movement, and his part in the founding of the Republican Party, with its opposition to the spread of slavery. He tracks as well the nuances of wartime rivalries and alliances and the fierce battle to enact revolutionary legislation after the war.
