Excerpt 1

“Thus were established the two great principles asserted by the Colonies, namely: the right of a State to govern itself; and the right of a people to abolish a Government when it becomes destructive of the ends for
which it was instituted. And concurrent with the establishment of these principles, was the fact that each Colony became and was recognized by the mother Country a FREE, SOVEREIGN AND INDEPENDENT STATE.”
