Battles on the frontier took place mostly between who?

Battles on the frontier primarily took place between European settlers, including American colonists, and Indigenous peoples. These conflicts often arose over land, resources, and differing ways of life. Additionally, colonial powers, such as the British and French, were involved, as they sought to expand their territories and influence in North America. The resulting skirmishes and wars reflected the complex dynamics of expansion, resistance, and the struggle for control.
