What significant event did the Declaration of Independence accomplish?

The Declaration of Independence is primarily recognized for officially announcing the American colonies' decision to separate from Great Britain. Drafted by Thomas Jefferson and adopted by the Continental Congress on July 4, 1776, this document articulates the philosophical justification for independence, asserting that all individuals are entitled to certain unalienable rights, including life, liberty, and the pursuit of happiness. It served not only as a formal statement of separation but also as a rallying point for the colonies to unify in their struggle against British rule. The Declaration profoundly influenced future democratic movements by establishing the principles of self-governance and the right to aspire toward independence.

The other options reflect successful outcomes unrelated to the purpose of the Declaration. The formation of the United Nations occurred much later, created after World War II to promote international cooperation. The Constitution, which established the framework for the government of the United States, was ratified in 1788 long after the Declaration was adopted. Finally, the end of the Civil War was marked by events primarily occurring in the 1860s with absolutely no direct connection to the Declaration of Independence.
