Oliver Hudson Kelley organized the National Grange, Patrons of Husbandry, in Washington D.C. on December 4, 1867. The Wisconsin State Grange was organized on October 24, 1872, by National Deputy J. C. Abbott, and South Greenville Grange No. 225 was organized on October 27, 1873, by State Deputy James Brainerd. Of 500 Granges organized in Wisconsin, South Greenville Grange No. 225 is the oldest continuously active grange, and in 1973 it was the first to celebrate its centennial. The Grange is unique in having first organized on the national level and then on the local level. Patrons of Husbandry, the Grange, is America's and the world's oldest and only rural family fraternity, aiming to serve all the interests of rural and urban people. The Granger Laws regulating monopolies and Grange sponsorship of cooperatives greatly influenced agricultural and industrial growth.
