Popular sovereignty means that the ultimate political power in a country comes from the people, not from a king, dictator, or some higher authority.

Simple meaning

  • The government is created by the people.
  • The government’s power is only legitimate if it reflects the “will of the people.”
  • If the people withdraw their consent (through elections, protests, or legal processes), the government can be changed.

A common way to phrase it: the government rules only with the “consent of the governed.”

In democracy and the U.S.

  • In democracies, popular sovereignty shows up through voting, elections, and participation in politics.
  • In the United States, it’s expressed in phrases like “We the People” in the Constitution and “deriving their just powers from the consent of the governed” in the Declaration of Independence.
  • It’s considered one of the core principles behind modern democratic government.

Historical example: slavery debate

In the 1800s in the U.S., “popular sovereignty” was also used in a narrower way: people in new territories would vote on whether to allow slavery (for example, under the Kansas–Nebraska Act), which helped spark violent conflict like “Bleeding Kansas” before the Civil War.

TL;DR: Popular sovereignty is the idea that the people are the true source of political power, and governments are only legitimate when they govern with the people’s consent.
