Step-by-step explanation:
The U.S. Declaration provides evidence that governments derive their power from the people through the principle of popular sovereignty. In the Declaration, it states that governments are instituted among men, deriving their just powers from the consent of the governed. This means that the government is only legitimate if it has the consent and support of the people it governs.
This concept helps lay the foundation for democracy in the United States by emphasizing that the power of the government comes from the people themselves. It establishes the idea that government is accountable to the people and should serve their interests. This empowers individuals and creates a system where the people have the ability to participate in the decision-making process through voting and other democratic practices.
