By signing the dói, what statement did it say to great britain

The Declaration Of Independence written by Thomas Jefferson and adopted by the Second Continental Congress stated the reasons why the British Colonies sought of independence. The entire documents reason is stated in the preamble and stated the reasons why the colonies overthrew their ruler and chosen to be a separate nation.

In general the document was saying The United States wanted to have a different government. They said this because the king failed to protect the rights to life, liberty and the pursuit of happiness.

Hope this Helps! :)
