The Grange, officially named The National Grange of the Order of Patrons of Husbandry, is a social organization in the United States that encourages families to band together to promote the economic and political well-being of the community and agriculture. The Grange, founded after the Civil War in 1867, is the oldest American agricultural advocacy group with a national scope. The Grange actively lobbied state legislatures and Congress for political goals, such as the Granger Laws to lower rates charged by railroads, and rural free mail delivery by the Post Office.
