Technically all wars are “border disputes.”
WW2? Dispute over Germany’s borders.
American civil war? Dispute over whether the border between the Union and Confederate existed.
War in Afghanistan? Dispute over the borders of Taliban administration.
I don’t know about other states, but in upstate New York a village is a legal entity that is a defined area within a town. A town is a subdivision of a county.
In other states, I think they don’t fully subdivide counties. So every person in one of those states either lives in an unincorporated part of a county, or a town/city. Those who live unincorporated are only governed by the county, while those in towns/cities are governed by both town and county.
So in New York there are no unincorporated parts of counties. Everyone lives in a town, which is part of a county. Some people may also live in villages, which are areas in towns.
Edit: for example, the village of Seneca Falls is in the town of Seneca Falls, which is in the county of Romulus.
