What are the first ten amendments to the US Constitution known as?

The first ten amendments to the U.S. Constitution are known as the Bill of Rights. This collection of amendments was ratified in 1791 and was introduced to protect individual liberties and address the concerns of those who feared that a strong central government might infringe upon personal freedoms. The Bill of Rights includes essential protections such as freedom of speech, religion, the right to bear arms, and protections against unreasonable searches and seizures, among others.

The other options refer to different historical documents or agreements. The Articles of Confederation were the first governing document of the United States, which was later replaced by the Constitution. The Magna Carta is a historical English charter that limited the powers of the king and laid the groundwork for modern democracy and legal principles but is not related to the U.S. Constitution. The Universal Declaration of Human Rights is a United Nations declaration adopted in 1948 that outlines fundamental human rights but is separate from U.S. constitutional law. This context illustrates why the Bill of Rights is the correct answer, as it specifically addresses the first ten amendments that are crucial in defining and protecting individual rights in America.
