Little Crow III (Dakota: Thaóyate Dúta; 1810 – July 3, 1863) was a Mdewakanton Dakota chief who led a faction of the Dakota in a five-week war against the United States in 1862. In 1846, after surviving a violent leadership contest with his half-brothers, Taoyateduta became chief of his band and assumed the name Little Crow. He played a pivotal role in signing the 1851 Treaty of Mendota which ceded most of their lands in present-day Minnesota and Iowa to the United States. In 1858, Little Crow led a delegation of Dakota leaders to Washington, D.C., where they were pressured by the U.S. government to give up their remaining holdings north of the upper Minnesota River. Faced with anger and mistrust at home, Little Crow lost an election for tribal spokesman in 1862, after which he tried to change his traditionalist ways. That summer, severe economic hardship, starvation, and tensions with government Indian agents, fur traders, and a fast-growing population of European and American settlers led to unrest among the Dakota, particularly the younger generation of hunters. On August 17, 1862, four Dakota hunters killed five Anglo-American settlers including two women. Fearing punishment, they pleaded for help from a faction of Dakota chiefs and headmen who wanted an all-out war to drive settlers out of the region. Their chosen leader was Little Crow, who initially tried to dissuade them. He pointed out the futility of fighting against the "white men," but finally agreed to lead them. Little Crow pledged to die with them and triggered the massacre of hundreds of settlers, as well as the capture of nearly 300 "mixed-blood" and white hostages, almost all women. Little Crow met significant opposition from many Dakota, particularly farmers and Christian converts, who preferred to maintain peace with the United States, objected to the killing of civilians, and wanted to free the captives. In September, Little Crow exchanged a series of messages with Colonel Henry Hastings Sibley offering to negotiate, but Sibley refused to begin talks until the hostages were released.
