Why did native Americas have to give up land in the treaty of greenville?

Native Americans had to give up land in the Treaty of Greenville, signed in 1795, as a result of military defeat and pressure from American settlers who were expanding westward. Following the Northwest Indian War, which pitted various Native tribes against American forces, the treaty was seen as a way to establish peace and facilitate settlement in the Northwest Territory. The agreement ceded significant portions of land to the United States, undermining Native American sovereignty and their traditional territories. This loss was a significant turning point in the ongoing conflict between Native Americans and European settlers over land rights.
