Letter Exchange between Pope Innocent IV and Güyük Khan (1245-1246)
In the late 1230s, the Mongols began raiding Eastern Europe, besieging, conquering and sacking cities and towns, and slaughtering their populations. Between 1236 and 1242, their military campaigns had wrought major devastations across Russia, Poland, Hungary and the Balkans. Polish forces sought to stop the Mongol onslaught but were crushed at Liegnitz/Legnica (April 9th, 1241); the Hungarian army met the same fate a few days later, at the Battle of Mohi (April 11th, 1241). The Mongol victories opened up Central Europe to Mongol raids, leading to even more destruction, displacement and massacres. These developments terrified Western political and religious leaders. Although the Mongols withdrew from most of the Balkans and Central Europe soon afterwards (as a result of internal struggles within their empire), the shock of their brutal invasions and conquests remained. Seeking to gauge the intentions of the conquerors and convince them to cease their invasion of the West, Pope Innocent IV (1243-1254) sent an embassy with two letters to the Mongol Khan Güyük. Below are excerpts from the second papal letter and the khan’s response.
Pope Innocent IV to Güyük Khan:
[...] It is not without cause that we are driven to express in strong terms our amazement that you have
invaded many countries belonging both to Christians and to others, and are laying them waste in a horrible
desolation, and with a fury still unabated you do not cease from stretching out your destroying hand to
more distant lands, but, breaking the bond of natural ties, sparing neither sex nor age, you rage against all indiscriminately with the sword of chastisement.
We, therefore, following the example of the King of Peace [i.e. Jesus Christ], and desiring that all men
should live united in concord in the fear of God, do admonish, beg and earnestly beseech all of you that for
the future you desist entirely from assaults of this kind and especially from the persecution of Christians,
and that after so many and such grievous offenses you conciliate by a fitting penance the wrath of Divine
Majesty, which without doubt you have seriously aroused by such provocation. Nor should you be
emboldened to commit further savagery by the fact that when the sword of your might has raged against
other men Almighty God has up to the present allowed various nations to fall before your face. For
sometimes He refrains from chastising the proud in this world for the moment, for this reason, that if they
neglect to humble themselves of their own accord He may not only no longer put off the punishment of their wickedness in this life but may also take greater vengeance in the world to come.
On this account we have thought fit to send to you our beloved son [the Franciscan Giovanni DiPlano
Carpini] and his companions the bearers of this letter, men remarkable for their religious spirit, comely in
their virtue and gifted with the knowledge of the Holy Scripture. Receive them kindly and treat them with
honor out of reverence for God, indeed as if receiving us in their persons, and deal honestly with them in
those matters of which they will speak to you on our behalf. And when you have had profitable discussions
with them concerning the aforesaid affairs, especially those pertaining to peace, make fully known to us
through these same Friars what moved you to destroy other nations and what your intentions are for the
future, furnishing them with a safe-conduct and other necessities on both their outward and return journey, so that they can safely make their way back to our presence when they wish.
Lyons, 13th March 1245

Güyük Khan to Pope Innocent IV:
We, by the power of the Eternal God, the Universal Khan of all the nations, command the following:
If this reaches peoples who have made their submission, let them respect and stand in awe of it.
This is a directive sent to the great Pope; may he know and pay heed. The petition of the assembly
convened in your lands has been heard from your emissaries.
If the bearer of this petition reaches you with his own report, you, who are the Great Pope, together with all
