Answer: Popular Sovereignty
Explanation:
The principle of Popular Sovereignty in basic terms means that the Government governs the nation only by the consent and authority of the people in the nation which is given to them during elections by way of voting.
If the government no longer serves the purpose for which it was put in power, the people are well within their rights to recall them by impeachment. This was the principle under which independence from Britain was declared by the founding fathers because the British government no longer served its purpose.
