His stand was brave yes...but how many centuries did they fight muslims? 8? 9?
In that period they lost and continued to lose. Syria, Anatolia, Egypt, Libya, Jordan were all lost.
And now it looks like they are about to give up their own ancestrial lands with the most recent riots there as they continue to bow down.
I guess you’ll just have to sack up, get off your ass and show them how it is done.
Your point is what?
That the Byzantine Empire by itself should have been able to withstand all comers? Not only was it hit by the Arabs, but the Persians, the Bulgars, the Seljuk Turks, the Normans, and the Crusaders all attacked it from time to time. The Fourth Crusade even managed to take Constantinople in 1204 with the Franks controlling the God-given city for several generations.
If you want to find a villian, try the Fourth Crusade. I would argue that the Byzantines performed pretty remarkable service by holding out until Tuesday, May 29, 1453.
