according to the declaration of independence, from whom do governments get their power?

According to the Declaration of Independence, governments get their power from the consent of the governed. The document states that governments are instituted among men to secure their unalienable rights, and they derive their just powers from the consent of the people they govern. If a government becomes destructive of these rights, it is the right of the people to alter or abolish it and institute a new government that will better ensure their safety and happiness
