The first defenestration was during the Hussite wars in 1419 at Prague , and the second is the "famous one" which started the 30 years war (1618-1648) when they booted 7 members of the council out of the Hradschin's window. The end of this religious war was Wallenstein's assassination at Eger in 1643 which lead to the Westphalian peace 1648. Wallenstein was assassinated by his own Catholics because they misunderstood his efforts for peace between the warring parties as treason. After so many years of religious war there were not many inhabitants left. To assassinate Wallenstein, they killed his officers at a banquet and this was done by Catholic Scotsmen Leslie, Butler and Gordon who fought on the side of the German Kaiser. Wallenstein himself was run through with a spear while he was asleep in his bed by a Frenchman named Deveroux on the orders of the German Kaiser for whom Wallenstein had fought battles for 25 years. If you travel to Eger you can visit the old ! rooms where this happened. The last defenestration was of Jan Mazaryk, the son of the first president of Czechoslovakia Thomas Mazaryk in 1948.
