What were the Indian's running from while going west?

The Indigenous peoples of North America, often referred to as "Indians," were not a monolithic group and had varied reasons for moving westward. Many were escaping the encroachment of European settlers, which led to loss of land, resources, and traditional ways of life. Others sought to evade violence, broken treaties, and forced relocation, such as during events like the Trail of Tears. Additionally, some tribes migrated in search of new resources or to avoid conflict with other tribes.
