Of course, after a word arc culminating in Hussites, it's hard to resist adding defenestration.
If you've learnt just a little French, you'll recognise the root of this word is common to fenetre, French for window. Defenestration is the act of throwing someone out a window.
In 1419, seven town councillors were thrown out the window in Prague. This was not trivial: they were thrown to their deaths.
This very event is the origin of the word defenestration, and it also precipitated the Hussite wars.
And in a spectacular effort to entrench the word in history, almost two hundred years later they held another defenestration event - this time, from Prague castle.
As you might expect, that precipitated another war - the Thirty Years War.
