Which founding document emphasizes the concept of inalienable rights?

The Declaration of Independence is the founding document that emphasizes the concept of inalienable rights. This document articulates the belief that certain rights are inherent to all individuals and cannot be taken away or denied. Specifically, it asserts that individuals are endowed with rights such as "Life, Liberty, and the pursuit of Happiness." These rights are described as inalienable, meaning they are essential and cannot be surrendered or transferred.

This foundational idea underpins the philosophy of governance in the United States, highlighting the importance of protecting individual freedoms and the necessity of government being accountable to the people. The Declaration serves as a cornerstone for American identity and democratic principles, influencing both the development of the Constitution and subsequent amendments that further secure individual rights.
