Final answer:
Most settlers moved to the frontier for economic opportunities, to spread Protestant ideals, and to escape racism in the South.
Step-by-step explanation:
The majority of settlers moved to the frontier for various reasons. White Americans of means moved west in search of riches, such as gold, cattle, or farming. They also had a sense of duty to spread Protestant ideals to native inhabitants. European immigrants, particularly those from Northern Europe, also made the journey to settle in ethnic enclaves. African Americans escaping racism in the South also headed west. In all, the frontier was a clash of cultures, races, and traditions that defined the emerging new America.
