Which of the following amendments is NOT part of the Bill of Rights?

The Thirteenth Amendment is not part of the Bill of Rights because it was ratified after the original ten amendments that make up the Bill of Rights were adopted in 1791. The Bill of Rights was created to protect specific individual liberties and limitations on government power, reflecting the values of the time in establishing rights related to freedom of speech, religion, assembly, and more. In contrast, the Thirteenth Amendment, ratified in 1865, abolished slavery and involuntary servitude, addressing a significant social issue in the United States. It is important to understand the historical context and purpose of the Bill of Rights, which is distinct from later amendments that addressed other critical aspects of constitutional law and civil rights.
