Answer:
The Declaration of Independence is the founding document of the United States of America (USA). The Continental Congress of the British Colonies in North America approved the declaration at the Independence Hall in Philadelphia on July 4, 1776. The document proclaimed that the original thirteen US colonies were "free and independent states." It was the last step in a long process that led the colonies to definitive separation from Britain.
With independence, the War of Independence began, in which the colonists fought for five years against the English troops.
The United States War of Independence lasted for five years. The settlers defended their independence through the Continental Army, a force created shortly after the declaration. After the break with the colony, a legal device was developed in the United States that allowed citizens to arm themselves. This idea has made gun ownership in the United States included in the US Constitution.
