Signing of the Declaration of Independence
On July 4, 1776, the Continental Congress convened in Philadelphia to approve the Declaration of Independence. This marked a monumental step as thirteen American colonies declared independence from British rule.
The document, primarily authored by Thomas Jefferson, articulated the colonies’ reasons for seeking freedom, emphasizing inherent rights to life, liberty, and the pursuit of happiness.
This declaration not only spurred the Revolutionary War but also laid the groundwork for the United States’ democratic ideals. It was a defining moment that rallied the colonies and established a new nation based on freedom and equality principles.
Ratification of the U.S. Constitution
