It was accepted because representatives of the American colonies, with the exception of Georgia, drafted a document to the English king George III in which they protested against the abusive measures, called intolerable laws, imposed by the English, but reaffirmed the loyalty to the English king. The English crown imposed more abusive measures on the colonies as a result of its discontent.
As a result, the colonial elite met again and concluded that it was no longer possible to remain under English rule in view of the crown's disrespect for colonial interests. Thus, the declaration of independence was issued, which was issued on July 4, 1776.
The process of independence of the English colonies led to an armed conflict with England, which sought to secure its rule over the colony. The war of independence of the United States extended until 1781, with a battle in the city of Yorktown.
With the end of the war, the English signed the Treaty of Paris in 1783, in which they recognized the independence of their former colony.
