Who did not contribute to the contribute to the creation of the US?

Indigenous peoples, who inhabited the land long before European settlers arrived, did not contribute to the creation of the United States in the context of its founding documents and governmental structures. Additionally, enslaved Africans and their descendants were largely excluded from the political processes and decision-making that shaped the nation. Their contributions to American society and economy were significant, yet they were denied recognition and rights in the formation of the U.S. government.
