The Defenestration of Prague (detail at the window).
Greater Bohemia, consisting of Bohemia, Silesia, Moravia and Lusatia, had been torn between Protestant and Catholic, German and Slav for two centuries, ever since the martyrdom of the reformer Jan Hus. Although Protestants had a majority on paper, they differed so greatly among themselves as to be a minority. Power resided with the Roman Catholics. Under a Letter of Majesty issued by Emperor Rudolph II, freedom of conscience and worship were granted in Bohemia. This freedom was not total. All Protestants were required to form one denomination. However, they were permitted to build churches in cities which had none.
Rudolph died before an interpretation of the act could be made. Catholics seized various pretexts to forbid Protestants to build churches. Rudolph's successor, the weak and elderly Matthias, placed power in the hands of an ardent Catholic who sought to centralize the government. Matthias' heir-apparent was Jesuit-trained and uncomfortable allowing Protestants freedom to worship in their desired fashion. These trends made Protestants uneasy.
Matthias left Prague. In his absence the area was ruled by regents, many of whom had resisted the Letter of Majesty. They arrested Protestant delegates who came protesting what was being done to the churches they tried to build.
Under the Letter, Protestants had a right to elect "Protectors" to settle disputes which might arise among themselves and to negotiate with the Catholics. The Protectors gathered in Prague on May 5, 1618, but contented themselves with drawing up a letter to Matthias. They set another meeting for the 21st.
The response from Matthias came back with such rapidity the protectors suspected it had been prepared in Prague and accused the regents of duplicity. The meeting on the 21st was nasty; the regents presented a letter from Matthias dissolving the assembly of the protectors. The protectors met on the 22nd and there is little doubt they plotted what happened next.
"Defenestration" is from Latin "de" meaning "out of" and "fenestra," "window." On this day, May 23 1618, they flung two of the offending regents out a window, intending to kill them. This was the famous Defenestration of Prague which sparked the war. Fortunately, the men thrown out the window were not seriously hurt. Some say they landed in a soft manure pile. What a foul way to start a war!
