Just adding to what everyone else wrote, concerning WW2, and all that jazz. If it wasn't for Poland, Europe would be entirely Moslem.
The battle of Vienna. The large-scale battle was won by Polish-Austrian-
German forces led by King of Poland John III Sobieski against the Ottoman Empire. If the Poles were to be defeated at Vienna, then
nothing would have stopped the Ottomans from conquering the entire continent, and spread their
religion. After the defeat of he moslems, John III Sobieski received a gift from the current Pope, I believe it was a Baton or a sword.
Also, the Poles had the best cavalry in the entire world
history! The "Winged Hussar's" had the best bred horses, and the biggest as
well. They are called "Winged" Hussar's because of the 2 wooden arches on the backs of the Polish cavalryman were lined with feathers from various or a specific
bird (not sure) and when the horses would charge toward the enemy, the
air passing the through the feathers would create a very, VERY
high-pitched screech that would scare the enemy's horses and cause havoc against enemy cavalry. The Polish horses were not affected because they were raised to adjust to that noise.
If it weren't for Poland, Europe would be an Islamic continent.
King John Sobieski III, along with the
Polish armies, especially the Winged Hussar's, defeated the Ottoman Empire at the
Battle of
Vienna, saving Europe from Islam.
