It was the "c. principle of popular sovereignty" that both the State constitutions and the Articles of Confederation had in common, since both these documents put a strong emphasis on the people being able to choose their representatives.
Popular Sovereignty is the basis of the United States government, that people of the country is considered to be the only source of governmental power in the country and the government must be governed with the consent of the people.
The people are the final authority in the government, the government received the authority from the people for example we the people of America written in the Preamble of the United States.
