Answer:
The Supremacy Clause is a formulation in the Constitution that stipulates that the Constitution and laws of the United States, as well as international treaties concluded by the United States, are the supreme law of the country. The clause also obliges state judges to abide by the US Constitution, laws, and international treaties, even if individual state constitutions and laws conflict with federal law. State constitutions also recognize the supremacy of the US federal Constitution. In this way, this clause guaranteed the preeminence of the federal government over state governments, by guaranteeing that their legislation is a priority before local legislation.
