Don’t think so. Probably still thought Hungary should be independent. Plus Hungary wasn’t trying to preserve slavery like secesh was.
All 13 original states were slave states when they seceded from England. Apparently being a slave state is not a disqualifier for gaining independence.
Also Lincoln supported Texas gaining independence from Mexico, and it *WAS* a slave state. Speech to Congress in 1848.
Any people anywhere, being inclined and having the power, have the right to rise up and shake off the existing government, and form a new one that suits them better. This is a most valuable, a most sacred right — a right which, we hope and believe, is to liberate the world. Nor is this right confined to cases in which the whole people of an existing government may choose to exercise it. Any portion of such people that can may revolutionize, and make their own of so much of the territory as they inhabit.Abraham Lincoln
No they weren’t. If anybody thought so Lincoln and the northern dominated congress made perfectly clear that they were willing to protect slavery effectively forever by express constitutional amendment. It passed the Northern dominated congress after the Southern delegation had withdrawn, was signed by the president and was ratified by a few states when Lincoln endorsed it in his inaugural address.
So much for that myth.
