Abstract: The firm of Greeley, Weed, and Seward led a revolution in political communications by promoting causes, parties, and candidates beyond the conventions of the second party system. Between 1840 and 1860, the firm championed economic policies built on free labor and free soil by advancing the agendas of the Whig and Republican parties. Greeley, Weed, and Seward led opposition to Jacksonian Democrats in the press and positions of elected power by organizing national interests that outlived regional competitors and survived the trials of war.
