The United States' first national constituion was the Articles of confederation. because this proved problematic and inefficient for the nation as a whole because it gave all the power to the states and none of them were on the same page, the Continential Congress came up with the Constitution, which eventually after adding the bill of rights as a compromise to the anti federalists, was accepted by enough of the states that it took effect and became the new 'law of the land'
A characteristic that all state constitutions have in common is that they all "include a bill of rights". These bills of rights were included to ensure that the government did not trample on the natural human rights of the citizens.
