State governments of the United States include the governments of the original 13 states and the governments of the remaining 37 which were admitted to the United States as authorized under Article IV, Section 3, of the Constitution of the United States. The idea of "dual sovereignty" or "separate sovereigns" is derived from the 10th Amendment to the Constitution, which states that "the powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people."
