The U.S.-Dakota War of 1862 was primarily triggered by the United States government’s repeated violations of treaties and its failure to deliver promised annuity payments and food supplies to the Dakota people.12
Several compounding factors led to this crisis:
- Economic Disruption: The depletion of game animals in the region and the pressure to adopt Euro-American agricultural practices disrupted the traditional Dakota way of life.23
- Starvation: Following a poor harvest in 1861 and a harsh winter, many Dakota faced severe starvation by the summer of 1862.23
- Government Neglect: With the federal government preoccupied by the American Civil War, treaty payments were significantly delayed.23
- Refusal of Credit: Local traders, who managed the reservation stores, refused to provide food on credit to the starving Dakota, further fueling tensions.2
These conditions reached a breaking point in August 1862, leading Dakota warriors to launch an offensive against settlers and government agencies in Minnesota.2
