Missouri v. Holland (1920) is a landmark Supreme Court case that upheld the power of the federal government to enter into treaties with foreign nations and enforced those treaties as "the supreme law of the land," as outlined in the Supremacy Clause of the U.S. Constitution. This case specifically addressed the issue of whether a treaty between the U.S. and Great Britain, which regulated the hunting of migratory birds, could supersede state laws. The Court ruled in favor of federal supremacy in matters of treaties, thereby defining treaties made under the authority of the United States as part of "the supreme law of the land."
