What is the primary purpose of the Bill of Rights?

The primary purpose of the Bill of Rights is to protect individual liberties. This collection of the first ten amendments to the United States Constitution was created to ensure that specific rights and freedoms of individuals are explicitly guaranteed against infringement by the government. These rights encompass fundamental freedoms such as speech, religion, assembly, and the right to a fair trial, among others.

By establishing these protections, the Bill of Rights serves as a safeguard against potential governmental overreach, ensuring that citizens have clearly defined rights that cannot be violated by the state. This foundational principle of protecting individual liberties is a cornerstone of American democracy, aiming to uphold the dignity and rights of all citizens.

Other options focus on aspects of government structure or powers rather than individual rights. The duties of the President, the structure of Congress, and the definition of state powers do not address the primary aim of the Bill of Rights, which centers solely on the protection of personal freedoms.
