Was wondering if anyone can recall any hot / nearly hot conflicts between US States or groups of US States, other than the American Civil War? What I’m after are incidents where state militias were raised or formed up at the borders of other states, that sort of thing, not going so far as against the Federal Government though. Seems like there was a border war or two back in the 1800s but I can’t seem to find them on Google or Wiki. I’ve tracked down the odd rebellion or [two](http://en.wikipedia.org/wiki/Category:Rebellions_in_the_United_States) but haven’t found whole States squaring off. Maybe I’m using the wrong search terms or have glossed over them or simply imagined them?

The state of Ohio engaged in some fisticuffs with people from what was to become the state of Michigan over the location of the border between them. You can look the stituation up in Wikipedia for a good overview of what happened. Of course, Michigan was not yet a state at the time, so it doesn’t quite match the requirements of the OP.

There was a fair amount of bluster between the colony of New Hampshire and the colony of New York over the property that eventually declared a pox on both their houses and got itself organized as Vermont, but I don’t think that anything occurred that could be called a “war” subsequent to the Declaration of Independence.

And once a Constitution was adopted, all the states tended to go along with using courts to decide issues.

(The casualties in the Toledo War were one Michigan cow and the broken arm (inflicted by the woman who had owned the cow) of the drunken Ohioan who shot it.)

[The Aroostook War](http://en.wikipedia.org/wiki/Aroostook_War), between Maine and New Brunswick, was almost certainly the only war between a US state and a Canadian province (both terms defined broadly, of course).

Massachusetts and some of the other New England states were pretty mad about “Mr. Madison’s War” of 1812, but I don’t think any fisticuffs ensued except for some sharp-witted editorials and a pamphlet or two. And that’d be “State against the Feds” which is still going on, really.

Massachusetts also got huffy about “[The Southwick Jog](http://www.southwickma.org/Public_Documents/F000102F9/S00476B50-00476B5B)” that pegs into CT a little bit. (Warning: link to PDF) But that’s more of a border dispute too. Nothing got hurt except the reputations of long-deceased cartographers.

I’ll see your Aroo and raise you a [pig](http://www.nps.gov/archive/sajh/Pig_War_new.htm), though it’s admittedly beyond the state v. province parameter and effectively the last (little-known) dispute over the Canadian/U.S. border.

Oklahoma and Texas fought over who controlled the Red River for decades… the rivalry between the University of Texas and the University of Oklahoma (the Red River Shootout) is likely a direct reference to this.

In 1839 Iowa and Missouri had a set to over the location of their common border and the identity and location of the “rapids of the Des Moines River.” It started when a Missouri sheriff attempted to collect taxes from people who regarded themselves as Iowans. This was important because Missouri was a slave state and Iowa, then a territory, was free soil under the Missouri Compromise of 1820. Missouri and Iowa militias were called out but actual blood shed was forestalled by a federal survey. This was the [Honey Tree War](http://www.iptv.org/iowapathways/myPath.cfm?ounid=ob_000106).

Well, maybe a little more than mere bluster. Ethan Allen and his Green Mountain Boys cut their teeth terrorizing “Yorkers” before they joined the colonial cause in the American Rev. (They would take Ft. Ticonderoga from the Brits after they joined that fight.) One account I read told of how one Benjamin Hough, before he was run off from the disputed land, got 200 lashes across his bare back for merely being a NY justice of the Peace.

Probably counts as a rebellion (as it was between the US and Utah) but there was the [Utah War](http://en.wikipedia.org/wiki/Utah_War) of 1857-1858 when President Buchanan attempted to depose Bringham Young as governor of Utah. A bit of a damp squib as wars go (though did result in the [Mountain Meadows Massacre](http://en.wikipedia.org/wiki/Mountain_Meadows_Massacre) )

Well I was going to go Oyster War – but since that is taken and seeing as some folks have stretched states to equal colonies how about Virginia Governor Alexander Spotswood sending an armed contingent (led by Royal Navy Lieutenant Robert Maynard) into North Carolina to deal with Blackbeard the Pirate. North Carolina Govern Eden had already pardoned Blackbeard. (Eden reportedly shrugged at pirate activity and possibly shared in Blackbeard’s booty.)

So not … quite… VA vs. NC – more like if the NC governor pardoned Beltway Sniper John Muhammad and the Virginia Legislature and Governor authorized and spent tax money to arm and send a detachment of National Guard Troops, led by an Army officer, into North Carolina to kill Muhammad.

Maybe close in spirit - but not quite - re the OP?

[/QUOTE]

But that wasn’t between two states, it was more like a civil conflict within the state. I think the OP is explicitly asking about conflicts between states, not uprisings against the federal government or a domestic disturbance.

If you’re going to count simple armed uprisings against the feds, then there’s the Whiskey Rebellion of 1794 and Shay’s rebellion of 1786. I suppose some of the race riots of the twentieth century were severe enough that they could be considered uprisings. A race riot in Atlanta around the turn of the twentieth century involved gun battles between blacks and whites in the streets, and killed more than a hundred people, most of them black. Some horrified observers in Europe considered it a small race war. Should Indian wars count? Those went on more or less continuously throughout the nineteenth century.

I was going to say John Brown’s raid on Harper’s Ferry, but that probably ought to be considered part of the Civil War.
