American Indian Wars

The American Indian Wars, also known as the American Frontier Wars, and the Indian Wars, were initially fought by European colonial empires, the United States, and briefly the Confederate States of America and Republic of Texas against various American Indian tribes in North America. These conflicts occurred from the time of the earliest colonial settlements in the 17th century until the end of the 19th century. The various conflicts resulted from a wide variety of factors, the most common being the desire of settlers and governments for tribal lands. The European powers and their colonies enlisted allied Indian tribes to help them conduct warfare against each other's colonial settlements. After the American Revolution, many conflicts were local to specific states or regions and frequently involved disputes over land use; many involved retaliatory violence.

As American settlement expanded westward after the American Revolution, conflicts between the United States and Native American nations increased in scale and frequency. A major turning point came during the War of 1812, when Native confederacies in the Old Northwest and the Southern United States allied with the British against the United States. Following the war, armed resistance continued in some regions, but relations between the United States and Native nations were increasingly governed through treaties that transferred large areas of Indigenous land to the United States. Historians have noted that the United States frequently failed to uphold treaty obligations, contributing to recurring disputes and further conflict.

The Indian Removal Act of 1830 authorized the president to negotiate treaties exchanging Native American lands east of the Mississippi River for lands in the west.
