Correction, his state attempted to leave the Union.
Did any foreign power recognize it as a separate state?
Take your bandwagon fallacy and appeals to force and stick 'em where the sun doesn't shine. I've told you about that stuff, and now I'm going to start getting really short with you, because you won't listen and you just keep blowing the same snot. You know it's BS, but you keep posting it.
The CSA had one foreign power give outright diplomatic recognition - the Germanic state of Saxe-Coburg Gotha. It also obtained an implicit recognition from the Vatican, which repeatedly addressed the CSA as a government in its own right.
It should be noted that for the first three or so years of the United States' existence after 1776 they had but a single foreign power that recognized their flag - the tiny island of St. Eustasius in the carribean, whose Dutch governor made a decision on his own to recieve the United States diplomatically. Thus the confederacy circa 1863 was better off in terms of diplomatic recognition from abroad than the United States circa 1777.
