During the Civil War the key policy-maker in Congress was Thaddeus Stevens, as chairman of the Ways and Means Committee, Republican floor leader, and spokesman for the Radical Republicans. Although he thought Lincoln was too moderate regarding slavery, he worked well with the president and Treasury Secretary in handling major legislation that funded the war effort and permanently transformed the nation's economic policies regarding tariffs, bonds, income and excise taxes, national banks, suppression of money issued by state banks, greenback currency, and western railroad land grants.
