You said muslims but the conquers in question were ottomans from Turkey.
Ergogen thinks he is Sultan Mehmed II all over again..... he may be
The Ottoman Empire was a muslim caliphate. The ottoman muslims occupied large portion of Europe.
Muslims is acurate. The entire middle East is on call to re-establish the caliphate. That was why we were attacked on 911. To the Muslims, it was a call to establish the caliphate and continue the invasion of Europe and the conquering of the world.
Muslims were staging incursions into Europe long before the Ottomans, perhaps most notably the Umayyads in Spain.
