What is the term used for the introduction to the Constitution?

The term used for the introduction to the Constitution is "Preamble." The Preamble serves as a concise opening statement that outlines the fundamental purposes and guiding principles of the Constitution. It establishes the reasons for the document’s creation and sets forth the core values that the framers intended to promote, such as justice, liberty, and the general welfare. The Preamble is a critical part of the Constitution as it provides context for understanding the rest of the document, reflecting the aspirations of the framers and the foundational ideals of the nation.

Other choices, while similar in purpose, do not specifically refer to the introduction of the Constitution. The term "Prologue," for example, is generally used in a broader literary context and is not commonly applied to constitutional documents. "Introduction" and "Preface" also do not capture the formal and evocative nature of the Constitution's introductory section. Hence, "Preamble" is the appropriate term that uniquely identifies this critical element of the Constitution.
