One of the more interesting cases of secession conveniently ignored by the neo-yankee Lincoln cult is that of the Vermont Republic.
Vermont was disputed territory claimed by both New Hampshire and New York. The people of Vermont, including Ethan Allen and the Green Mountain Boys, didn’t choose to belong to either so they declared their independence of NH and NY and formed their own country. Vermont remained independent from 1777 to 1791, at which point it was admitted into the Union.
That's interesting,. Thanks for pointing it out!
I'm adding it my list of things to look up more details on while I'm roaming around the Library!
