The Declaration of Independence states that the role of a government is to protect the rights of the people. They believed all people have certain rights. These rights include the right to life, liberty, and the pursuit of happiness. These rights can’t be taken away or given up. They believed that when a government stops protecting the people’s rights, the people have no choice but to replace that government.
