The Declaration of Independence is important for the following reasons:
- It explained the ideals of liberty, justice, and equality.
- It announced that the American colonies were separate from Great Britain.
The other two responses, regarding setting up the U.S. government and giving Americans the right to vote for leaders, are not accurate in the context of the Declaration of Independence. The U.S. government was established later through the Constitution, and voting rights were not directly granted by the Declaration.
