Goodwin described the group in her biography as a Team of Rivals.There were two measures passed to raise revenues for the Federal government: tariffs (a policy with long precedent), and a Federal income tax.In 1861, Lincoln signed the second and third Morrill Tariffs, following the first enacted by Buchanan.He also signed the Revenue Act of 1861, creating the first U.S.income tax—a flat tax of 3 percent on incomes above $800 ().The Revenue Act of 1862 adopted rates that increased with income.The Lincoln Administration presided over the expansion of the federal government's economic influence in other areas.The National Banking Act created the system of national banks.The US issued paper currency for the first time, known as greenbacks—printed in green on the reverse side.In 1862, Congress created the Department of Agriculture.In response to rumors of a renewed draft, the editors of the New York World and the Journal of Commerce published a false draft proclamation that created an opportunity for the editors and others to corner the gold market.
