Which document begins with the phrase "We the People"?

The phrase "We the People" is the opening line of the preamble to the United States Constitution. This phrase is significant as it establishes the foundational principle of popular sovereignty, indicating that the authority of government is derived from the people. The Constitution was created to form a more perfect union, provide for the common defense, and secure the blessings of liberty, among other purposes.

In contrast, the other documents mentioned do not begin with this phrase. The Bill of Rights, which comprises the first ten amendments to the Constitution, focuses on individual rights and does not include that opening line. The Articles of Confederation served as the first governing document of the United States, but it is characterized by a focus on the states' rights and lacks the unifying phrase found in the Constitution. The Declaration of Independence articulates the colonies' reasons for seeking independence from Britain and begins with a different line that discusses the natural rights of individuals and the need to dissolve political ties. Thus, the Constitution is the only document among the options that starts with "We the People."
