Custer Invades the Black Hills

George Armstrong Custer, commander of the 7th Calvary, led an excursion into the Black Hills in 1874. His men ultimately found gold, setting off a stampede of prospectors into the sacred Black Hills, which were officially owned by the Lakota Sioux as part of the Fort Laramie Treaty of 1868. As a result, numerous boomtown, the most famous being Deadwood, developed around the Black Hills in South Dakota in 1875. This invasion and obvious breaking of the treaty led the Sioux to rebel against the authority of the federal government. This ultimately led to the infamous Battle of Little Bighorn.
