GREENBACK PARTY, the name for the American Inde pendent National Party, which held its first national convention in 1874. Its earliest appearance in a presidential campaign was in 1876, when its candidate, Peter Cooper, received 81,740 votes. It advocated increasing the volume of greenbacks (q.v.), forbidding bank issues, and the paying in greenbacks of all Government bonds not expressly payable in coin. In 1878, after fusing with certain labour groups, it changed its name to the Greenback Labor Party. By this and other fusions the party in that year (a period of very hard times) cast over i,000,000 votes and elected 14 congressmen. In 1880 it joined with other labour reformers and cast 308,578 votes for its presidential candidate, James B. Weaver, and elected 8 congressmen. In 1884 its candidate, Benjamin F. Butler, re ceived only I 75,37o votes, and the party disintegrated soon there after. Many of its adherents later joined the Populist Party, which was organized in 1891.
