Very interest how Europa barely talk about last and crucial battle ,,Siege of Vienna''. Ok. I will understand you why. This battle was first battle Ottomans lost. If they won Vienna, occupy Austria, Europa would be Islamic. Polish-Lithuanian Commonwealth Army called Hussari - Serbs in big number who run away from occupied Belgrade. So coalition of perfection Austro - Hungarian, German Slavic Alliance. Look those documentaries because if not Jan Sobietsky and some Hussar on horses we would be Islamic Continent.
Who knows, maybe it was planned and we destroy plans and got bombarded huhuh.
I didn't know Serbs has important part in battle. 
However, 20 000 strong Cavalry ,,Hussars'' Destroy those Islamic army first time, Ottomans first time used heavy artillery. Ottomans first fucked up Serbia but Serbs killed their sultan and last time some did that. Point is I see that European connection is in North-Eastern Europa have to be in brotherhood Alliance with Germans or Slavo-Germanic Kingdom...some one with crown and with faithful volk. Nothing else just Slavo Germanic Alliance. 

Slavic-German Alliance would be strong enough. I'll stay on this thread few more documentaries I have to see watch first to put the best one.
