This clause states that the laws of the federal government are the supreme laws, but only if such legislation has been constitutionally enforced. The supremacy clause would also include treaties, so the treaty between the national government and another body would be valid if they were also made following the rules listed in the Constitution. The Supremacy Clause establishes the system of federalism by establishing the order in which power will flow. The Constitution is the highest level of this power and other powers are delegated from it. The federal government is at the level below the Constitution, showing that all its power is delegated to it by the Constitution, so it must follow it. Below the federal government are state governments, which also have powers, but their powers are less than those of the federal government. However, the Constitution reserves powers to the State. This establishes a system of federalism because it establishes the two areas of government and decides which body will be supreme. The limit of this supremacy is the Constitution, and it is held by the federal government
