What is the importance of second treaty of fort Laramie and the medicine lodge treaty?

The second Treaty of Fort Laramie in 1868 helped establish peace between the United States and the Sioux tribes by defining tribal territories and allowing the tribes to continue their traditional ways of life. The Medicine Lodge Treaty in 1867 aimed to relocate Southern Plains Native American tribes to reservations in Indian Territory and establish peace, but ultimately failed to address underlying issues leading to conflicts. Both treaties highlight the complex relationships between Native Americans and the US government during westward expansion.
