When did people that were born equal and free start?

The phrase "all men are created equal" originates from the Declaration of Independence, adopted on July 4, 1776, in the United States. This concept emerged during the Enlightenment, when Enlightenment thinkers advocated for individual rights and equality. However, the practical realization of these ideals has evolved over time and continues to be a work in progress, as societal norms and laws have gradually shifted towards greater inclusivity and equality.
