The Declaration of Independence begins with the words "We, the people..." However, we have no explicit explanation of who these people are. Although the phrase is meant to represent the citizens of the United States, there is no consensus as to what that means. Therefore, the concept has been continually expanding in order to include new groups (for example, African Americans and women). This expansion has allowed more people to feel represented by the Constitution.
The Declaration's most famous sentence is, of course, this one: "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness."
