Equality is a village in Gallatin County, Illinois, United States. The population was 721 at the 2000 census. Near the village are two points of interest, the Crenshaw House and the Garden of the Gods Wilderness.
French settlers extracted salt near Equality as early as 1735, while Native Americans made salt here long before then. In 1803, the American Indians ceded their "Great Salt Springs" to the US government by treaty. The government then leased the springs, requiring the holder to produce a certain quantity of salt each year or pay a penalty. The salt works is referred to as the "United States Saline" in old documents.
Isaac White was in charge of the salt works in 1811. White volunteered for the Indiana militia that year, and was killed at the Battle of Tippecanoe. Special territorial laws permitted exceptions to anti-slavery treaties at these salines, and slaves were used extensively in manufacturing salt. The census of 1820 for Gallatin County listed 239 slaves or servants.
