This book is a narrative history of the thirty-year struggle to outlaw slavery, starting with the founding of the American Anti-Slavery Society in 1834 and extending until the abolition of slavery in the United States at the end of the Civil War.The core of the book consists of two sections: 1) the 20-year political struggle to restrict slavery through a succession of anti-extensionist parties starting in 1840 with the founding of the Liberty Party, extending through the Free Soil Party (1848-54) and ending with Abraham Lincoln being elected president as a Republican on the same basic platform as the Liberty Party in 1844. 2) The struggle by abolitionists to use the outbreak of the Civil War as a chance to rid the country of slavery using the executive wartime powers of the presidency.
