Which document is described in this excerpt?

The U.S. Constitution serves as the framework for the federal government and outlines the structure of the government and its powers. While it is a crucial document in American governance, it was created after the Declaration of Independence and does not focus on the justification for independence itself.

The Gettysburg Address is a speech delivered by Abraham Lincoln that commemorates the fallen soldiers of the Civil War and emphasizes themes of equality and national unity. Although significant, it does not address independence or the founding principles of the nation as articulated in the Declaration of Independence.

The Mayflower Compact was an agreement made by the Pilgrims in 1620 to establish a form of self-governance in their new colony. While it is an important early document in American history, it predates the Declaration of Independence and focuses more on governance within the colony rather than the quest for independence from Britain.
