The 1876 Greenback National Convention was held in Indianapolis in the spring of 1876. The Greenback Party had been organized by agricultural interests in Indianapolis in 1874 to urge the federal government to inflate the economy through the mass issuance of paper money called greenbacks. Peter Cooper was nominated for president with 352 votes to 119 for three other contenders. The convention nominated anti-monopolist Senator Newton Booth of California for vice-president; after Booth declined to run, the national committee chose Samuel Fenton Cary as his replacement on the ticket.^{[citation needed]} Cooper was 85 years old at the time of his nomination, thus the oldest person ever nominated by a political party to serve as President of the United States.
