Final answer:
The Kiowas and Comanches originated from the Great Plains and were relocated to Indian Territory (now Oklahoma) due to the Medicine Lodge Treaty of 1867. These tribes experienced significant disruptions to their traditional ways of life due to European colonization and now live mainly in Oklahoma reservations.
Step-by-step explanation:
The Kiowas and Comanches are Native American tribes originally from the Great Plains region. The Medicine Lodge Treaty of 1867 significantly influenced their history, relocating these tribes to Indian Territory, known today as Oklahoma. The treaty promised them permanent ownership of the land, unless superseded by another agreement with approval from three-fourths of a tribe's adult male population.
Although the treaty was meant to provide protection and support for the development of schools and farms, subsequent treaties and actions often undermined these promises. The traditional lives and economies of these tribes were disrupted by European contact and resettlement. Today, both the Kiowas and Comanches live primarily in Oklahoma, their populations concentrated on reservations where they continue to practice and preserve their cultural heritage.
