What are the first 10 amendments to the United States Constitution commonly known as?

The first ten amendments to the United States Constitution are commonly referred to as the Bill of Rights. This term signifies their purpose, which is to delineate and protect the fundamental rights and liberties of individuals. Adopted on December 15, 1791, the Bill of Rights was established to address the concerns of Anti-Federalists who feared that a strong central government would infringe upon individual liberties. Each amendment in this collection guards specific freedoms such as freedom of speech, religion, press, and the right to bear arms, among others. This foundational document has played a crucial role in shaping American law and protecting civil liberties, making the term "Bill of Rights" the most recognized and accurate label for these amendments.

Considering the other options, the Declaration of Independence refers to a different document that announced the American colonies' separation from Britain and is not related to amendments. The term Constitutional Amendments is broader and includes all amendments beyond just the first ten. Lastly, Rights of the Citizen is a general term that does not specifically identify these amendments, hence it lacks the precise historical context that "Bill of Rights" provides.
