Answer:
Americans
Step-by-step explanation:
According to a peace treaty with Great Britain, the western border of the USA was established along the Mississippi River, and the northern, in turn, along the Great Lakes. Previously, the territories between the Mississippi and the Appalachian mountains were left by the British to their Native American allies.
At the end of the War of Independence, the United States continued to wage war with the Indians in the Northwest Territories, which ended in 1795 with the signing of the Greenville Peace Treaty, according to which the Indian Confederation recognized the sovereignty of the United States and allowed white settlers to their lands. In addition, the United States negotiated with Spain on the disputed Southwest Territories, where active fighting was also conducted with the Indians. According to the Madrid Treaty, concluded in the same 1795, Spain recognized these lands as US possession and demarcated the border between them and Spanish Florida on the 31st parallel. In 1798, the territory of the Mississippi was created there.
After the Anglo-American War of 1812-15, the Indians lost the support of Great Britain and could not provide substantial expansion to the American expansion. By the decisions of Congress and the administration of President Jackson, many Indians were evicted across the Mississippi River in the 1830s.
