The Indians were very territorial. If their land was in danger they would protect it. White people were establishing mining communities on the Indian ground. The settlers were also trapping and hunting and started to take over. Trouble started because at this time the Civil War was progressing, this made the Indians mad. The Sioux Indian tribe took action by Minnesota uprise. This uprise was appointed in the year 1862.The Sioux were defeated by the Union soldiers.
After the defeat, the Sioux got extremely mad and started on a killing spree known as the Chivington Massacre. This war was placed in the Western Plains. Laramie, Wyoming, Bozeman and Montana were also hot Indian war spots. The indian Wars pained the western frontier for many moons. Mining camps were overtaken and wagons were robbed.
Even though the federal government reserved many lands for Indians, the settlers were still moving to the locations. Many soldiers even said “the only good Indian is a dead one.” There were also good Indians that were murdered by the army in numbers of over 300.
This took place in Sand Creek Colorado. This is what is believed to start the spark that fueled the massacre.
