I spent some time in Austria a few years ago. Loved it. Beautiful country. But many there saw this coming. An Austrian friend told me "We kept the Muslims out for a thousand years, now we let them in one at a time".
Welcome to the multicultural world Austria!
Know how croissants got their name? The turks were invading Vienna, then a walled city, and the turks were digging tunnels under the city. Of course, they did this very early in the morning hours. And what profession is up in the morning: bakers.
Thus the bakers made the croissant "crescent" in memory of their luck and the defeat of the Turks.
