They seceded. They declared independence from the British Empire. They were not seeking to overthrow the British Government, displace King George, dissolve Parliament, etc. They Left. That was their aim all along. That's secession. Oh and by the way, all 13 colonies had slavery at the time. And then there is the matter that the sovereign states do have the legal right to unilaterally secede....to "resume the powers of government" they had delegated to the federal government as the express provisos passed by several states at the time of ratification of the constitution plainly said. They were on much firmer legal footing than the 13 colonies had been considering the colonies were not sovereign.
Please point out the provision of the United States Constitution that enumerates this pretend "legal right".

Hogwash.
