Well, I've done it. I've answered one of those livejournal sorts of thingies.
Interesting events of December 4:
(according to the ever reliable and oh so well edited Wikipedia)
771 Carloman, king of east Frankish "Austrasia", dies allowing his brother Carl to unite the Frankish kingdom. (This would be the same Carl later crowned "Imperator Augustus" by the Roman patriarch Leo III in the year 800 of the generally accepted Western era. History recalls him as Emperor Charles I or: "Chas the one, Chas the only (well, maybe not that), Chas the GREAT!")
1259 Henry III of England and Louis IX of France (St. Louis, to his good buddies) started an ignominious tradition by signing a treaty somewhere in the general environs of Paris. (This particular treaty of Paris is apparently sometimes called the Treaty of Albeville.) In it Hal gave up most of his ancestral lands in France in order to bribe Louie into not supporting some pesky upstart rebels back at home in England. Too bad it didn't prevent the little spat over who was the rightful King of France a few years later. The spat we call the hundred years war. (And it was actually a bit over a century in length should you think that's a rather gruesome title.) Not to mention the half dozen other wars between England and France also ended by treaties of Paris. The last one "ended" the Vietnam war, only to have the NVA overrun the short-lived South Vietnam a couple of years later.
1980 Led Zeppelin made public to the world that they no longer cared to play together. Not quite as depressing as failed treaties, nor as glamorous as pompous crusading Emperors, but interesting nonetheless.

And I'm sorry, but I can't really stop at three so . . .
1956 Alexander Rodchenko (another "Silver Age" painter. Cool stuff.)
1976 Benjamin Britten (Wow!)
And in the bad people camp:
1642 Cardinal Richelieu
Well, I hate to admit this, but I can't find something more reliable than Wikipedia online without paying money, so I'm just going to leave it at this. Some of the dates (even if not necessarily noted as such) are surely "old system" sorts of Julian dates, but hey, who's counting?
