question: What Supreme Court case focuses on the Louisiana Purchase?
article: Louisiana Purchase
candidates: The historian James Loewen is among those who assert that the United States purchased only France's claim to the Louisiana Territory, as the land belonged to the tribes who inhabited the area. In his view, the US acquired the lands slowly throughout the nineteenth century by purchases from individual Native American tribes and by wars against them. The question is discussed at length in the article on Aboriginal title in the United States, as well as in articles on the American Indian Wars and the U.S. Supreme Court case "Johnson v. M'Intosh".
