The “Vermont Republic” was the short-lived result, an independent nation that existed for a few years before merging with the other colonies to form the United States of America. The Republic of Vermont has also been known as “the reluctant republic” because the Vermonters didn't really want a country of their own- they just wanted to be able to join the United States on their own terms rather than on terms dictated by their enemies in New York.
They eventually did achieve this aim, entering the new nation as a full-fledged state. But just like Texas- their opposite in virtually every other way- Vermont has never really forgotten that it was once an independent nation. If it was still independent today, perhaps this song would be its national anthem!
