"There is also in the East another Christian people, who are very warlike and valiant in battle, being strong in body and powerful in the countless numbers of their warriors. They are much dreaded by the Saracens and have often by their invasions done great damage to the Persians, Medes and Assyrians on whose borders they dwell, being entirely surrounded by infidel nations. These men are called Georgians, because they especially revere and worship St. George, whom they make their patron and standard-bearer in their fight with the infidels, and they honor him above all other saints. Whenever they come on pilgrimage to the Lord's Sepulchre, they march into the Holy City with banners displayed, without paying tribute to anyone, for the Saracens dare in no wise molest them. They wear their hair and beards about a cubit long and have hats on their heads."
Jacques de Vitry, Patriarch of Jerusalem, early XIII c.

“Rumours of Frederick’s preparations had reached the peoples of Georgia. The Queen of this country wrote to the head of the Church of Rome that the constable (chief of army of her kingdom) and a great number of her subjects were only awaiting the arrival of the German Emperor [3] to fly to the help of Palestine. The Georgians were considered a warlike people; they were feared by the Moslems; their pilgrims had the privilege of entering Jerusalem without paying the tribute imposed on other Christians… but the Tartar invasion prevented their leaving their own territory.”
William of Tyre, XII c.

“The nation [Georgia] bore a considerable part in the Crusades”
Archdeacon Ward, of Alexandria
"The sultan has won Georgians - the people which because of inaccessibility of their fortresses and indestructibility of their strongholds, greatness of their riches and valour of their soldiers did not know vicissitudes of life and powerful kings and princes of Syria and Rum accepted them as equal , because from for fear before their fury in fight, moreover, from which they ran, in powerlessness and weakness"
Juvayni (Ala'iddin Ata-Malik Juvayni), Iranian scholar, XIII century.
