Answer:
The 13 American colonies cut their political ties with Great Britain by publishing the Declaration of Independence, which was adopted by the Continental Congress on July 4, 1776. The Declaration enumerated the reasons for the colonies' desire for independence. The American colonies were able to seal an official alliance with the French government and receive French support in the battle against Great Britain by proclaiming themselves an independent country. North American colonists were increasingly at conflict with British imperial policies about taxes and frontier policy throughout the 1760s and early 1770s. When repeated protests failed to sway British policy and instead resulted in the closure of Boston's port and the establishment of martial law in Massachusetts, the colonial governments dispatched delegates to the Continental Congress to plan a colonial boycott of British products.
