"Suitable Answer" by Lado Gudiashvili, 1945. The artist depicted Rûm's knocked out envoy before Queen Tamar.

In July of 1203* the envoy of the Seljuk Sultanate of Rûm arrived in Tbilisi, the Kingdom of Georgia. His mission was to deliver his Sultan’s ultimatum to the Georgian Queen Tamar. It marked yet another attempt by the Seljuks to stem the Georgian southward advances. The story of this conflict is narrated in the contemporary Georgian, Armenian and Islamic sources. The Sultan of Rûm Ruknüddin Süleymanshah II (c. 1196–1204), son of Kilij Arslan II, who overthrew his brother, Sultan Kaykhusraw I and became sultan in 1196, fought hard, with considerable success, to reassemble a once vast state fragmented under his late father. Initially, his relations with the neighboring kingdom of Georgia were ostensibly peaceful, including the exchange of embassies and precious gifts. Through expansionism, the two regional superpowers eventually came into open confrontation in eastern Anatolia and the ruler of Rûm eventually felt strong enough to solve the Georgian problem once and for all by military means.
According to the Georgian chronicles the letter contained the following text:
"I, Ruknüddin, the Sultan of the entire world under heaven, the highest one, likened to the angels sitting beside God, sent (here) by the Great Mohammed, notify you of this, Tamar, the Queen of Georgia. You ordered the Georgians to take up arms and destroy God’s beloved Islamic people; then not satisfied with this, you imposed a vassal’s tribute on a free tribe. Now I am coming to restore justice for the house of the Persians, and to reform you and your people so that you will never dare to take the sword up again, which God has granted us. I will preserve life only to those who will come to my tent before I enter your country and humbly ask for mercy and assume the faith of the Prophet Mohammed and reject your faith, and break with their own hands the cross, on which they vainly set their hopes. And now wait for reprisals from me for the troubles you have inflicted upon all Muslims."When the letter was read aloud the envoy added:
"In reward for her obedience, the sultan promised to marry the Queen on the condition that she embraces Islam; if Tamar doesn’t want to denounce Christianity, he would number her among the other unfortunate concubines in his harem."When the messenger relayed the sultan’s demand, Zechariah Mkhargrdzeli, a Georgian General of Kurdish-Armenian origin, was so outraged that he slapped him on the face. According to medieval chronicler, who was watching these negotiations, Süleymanshah’s emissary was knocked out "lying down as if dead". When consciousness came back to the unfortunate diplomat, he heard the following words from Zechariah:
"If you weren’t an envoy, cutting your tongue out and then cutting your head off would be your punishment." **
The entire Georgian court was infuriated. It was evident that the war was inevitable and the Sultan’s military preparation entered its decisive phase. In order to win more time, the Georgians withheld their answer along with the beaten envoy. As there was no time to waste, the Queen immediately ordered to assemble the Kingdom’s army. Within ten days (that shows quite good mobilization capabilities of the Kingdom) considerable Georgian forces concentrated in Javakheti near the rock-cut Monastery of Vardzia. There Tamar addressed her soldiers inspiring them for decisive battle. Led by the Queen’s consort David Soslan and Generals Ivane Mkhargrdzeli and Shalva Toreli, the army immediately marched to the southwest accompanied by "David’s and Gorgasal’s banner" (flag of Georgia held by Tamar’s great grandfather David IV and attributed to the extremely popular early medieval warrior king of Iberia and call Constantinople's ally Vakhtang I the Wolf Head).
Meanwhile Süleymanshah, joined by his vassal beys and allies, crossed into the Georgian marshlands with a huge army and encamped in the Basiani valley, 60 km northeast of the city of Erzurum in what is now northeastern part of the Republic of Turkey (modern Turkish historians identify the vicinity of Micingerd (Mazankert) as the location).
When the Georgian army approached the town of Kars (called Kari (the Door) by Georgians) at a distance of 1 day’s march, they send off the envoys of the Sultan and the Tamar’s messenger with them, with her answer:
"I, who entrusted myself to the Omnipotent and Almighty God, and ever praying to the Virgin Mary, and with faith and hope on the Holy Cross, read your message which enrages God. Oh, Ruknüddin, don’t you know that every man who falsely swears by the name of the Lord will be wiped off the earth? While you write me such things, I am sending you an army of Christ lovers, not to ask humbly for mercy, but to crush your arrogance and presumption…And the soldiers I have sent are already waiting at your gates."Georgians made a rapid night time advance into Basiani and assailed the enemy’s camp in the early morning of July 27. In a pitched battle the Seljuk forces managed to roll back several attacks of the Georgians led by David Soslan and commenced counter-attacking, exposing their flanks to the Georgian forces in the rear. Their Commanders Ivane Mkhargrdzeli and Shalva Toreli used this opportunity and stormed a relatively disintegrated enemy formation, finally overwhelming them by pincer movement. The fierce Georgian attack finally broke the Seljuk ranks, the Sultan's banner was lost and the Sultan himself was wounded. That eventually resulted in panic within the Sultanate's forces and in their disorganized retreat. Süleymanshah had to withdraw from the battlefield seeking shelter behind the walls of Erzurum. Probably the defeat and wound accelerated his end that followed in 1204.
The Georgians captured an enormous booty and took many high-ranking prisoners. One of them later was recovered in exchange of one horseshoe. The victory at Basian showed that Tamar’s kingdom was dominant power in the region. It allowed Georgia to consolidate its position in the eastern Anatolia and keep the Seljuk resurgence in check, at the same time creating favorable conditions for further expansion of the Georgian sphere of influence. Next year, the Kingdom of Georgia invaded the eastern Roman province of Chaldia. This military expedition, that coincided with the 4th Crusade, resulted in creation of a new friendly state – the Empire of Trebizond, headed by Tamar’s relative Alexios I Komnenos.
Some time later, on the eve of the fifth Crusade, Amadeus, archbishop of Besançon, received a letter written by a crusader knight who called himself Gerbert de Boyz. The letter told about the news the author had heard in the East:
"Hear, too, other news worthy of your consideration and amazement. We have been able to confirm for certain, through messengers, the truth of the news we had heard, that with divine help the Christians from Iberia called Georgians, together with countless captive soldiers, heavily armed, raised up against the pagan infidels and have already conquered 300 castles and 9 great cities, the stronger ones they have manned, while the weaker ones have been burnt down… they’re coming to Jerusalem to win back the Holy Land subjugating all the territory of the pagans. Their noble king (Tamar's son George IV) is only sixteen years old, but he is equal to Alexander in strength and prowess…"The above mentioned letter, despite containing a highly exaggerated description, is one of the few documents showing that in Crusader States d'Outremer there were people who were informed about the military strength of the kingdom of Georgia and saw it as a possible ally.
* The battle is variously dated between 1202 and 1205, but 1203 or 1204 has lately been given preference.
** As a lawyer I want to underline two legal aspects of these words:
1. It seems like the punishment required by the law for insulting his/her majesty was as described in the above mentioned phrase.
2. Nevertheless Georgian government respected “diplomatic immunity” to a certain extent. Not commonly accepted practice in the middle ages.
