When did they encounter the Khans:Pope Innocent IV sent an embassy with two letters to the Mongol Khan Güyük in an effort to discover the intentions of the conquerors and convince the Khans to halt their invasions into Latin Christendom. Italian Franciscan Giovanni da Pian del Carpine, who left Lyon in April 1245 and arrived at the court of Güyük Khan arrived to Karakorum in July 1246, was the most important papal envoy to the Mongols.

Why did they encounter the Khans:On March 13, 1245, Pope Innocent IV sent a letter to the Mongols titled Cum non solum. In it, Pope Innocent asks the Mongols what their future plans are and urges to them to stop attacking Christians and other countries. Innocent also states his desire for peace (possibly unaware that in the Mongol vocabulary, "peace" is a synonym for "subjection").

What happened during the encounter: Güyük responded to the Pope's letter with a fairly typical Mongol demand for the Pope's submission and a visit from the rulers of the West in homage to Mongol power. Güyük had little understanding of distant Europe or the Pope's significance in it, aside from the fact that the Pope was sending a message from a region that the Mongols had not yet conquered.

What happened after the encounter: Afterwards, Khan wrote Pope a letter in response. In the letter, he stated that the pope must visit them in person together with all of his kingdoms, without exception, to serve them and show them respect. They won't accept the pope's submission until after that. And they will recognize them as their enemy if the pope disobeys God's command and acts against the Mongols' orders.

First person narrative:In 1000 CE, a single family ruled a vast empire that extended 23 million square kilometers from East Asia to Europe for more than 100 years. The Genghisid Dynasty, which ruled throughout that time period, was descended from the legendary warrior Genghis Khan. The founder of the Mongol Empire, Genghis Khan (1162–1227 CE), is recognized as one of the greatest military leaders in history. He was in his forties and still had his greatest military feats in front of him. His original name was Temujin. He had defeated his domestic enemies by that summer. He overcame his competitors with deadly cunning and advanced to become the first Great Khan of the Mongols. t is common knowledge that Genghis Khan and the Mongols were responsible for awful accounts of invasion, ruin, and bloodshed. The largest empire ever to exist was founded by this renowned clan leader and his immediate successors, and it covered the whole Asian continent from the Pacific Ocean to present-day Hungary in Europe. Without a clear strategic direction, outstanding organizational abilities, the fastest and toughest cavalry ever seen, an army of outstanding archers, the "devil's horsemen" in Western sources, the existence of politically fragile states throughout Asia, and of course, havoc and destruction, such an empire could not have been created. The majority of Mongols today are Tibetan Buddhists, but in earlier periods, particularly under the Mongol Empire (13th–14th centuries), they were shamans, with a sizeable minority of Christians who held positions of enormous influence. Overall, Mongols were quite tolerant of most religions and frequently supported multiple ones at once. Following the Mongols' loss, the bloodthirsty Mongol army and cavalry had to be resisted by the Christians. Güyük responded to the Pope's letter with a fairly typical Mongol demand for the Pope's submission and a visit from the rulers of the West in homage to Mongol power. Güyük had little understanding of distant Europe or the Pope's significance in it, aside from the fact that the Pope was sending a message from a region that the Mongols had not yet conquered.Consequently, a letter was delivered to the Mongols on March 13, 1245, by Pope Innocent IV. In it, Pope Innocent asks the Mongols what their future plans are and urges them to stop assaulting Christians and other countries. Innocent also expresses a desire for peace, but the emperor Khan misinterpreted Innocent's message because "peace" is a synonym for "subjection" in the Mongol language. This misunderstanding made the Khan more furious. The tendency of Genghis Khan is to always associate the bad label to Genghis Khan. Why only him and not the other Emperors who pillaged, massacred and did a whole bunch of things worse than the one who founded the Mongol Empire? Sometimes I wonder what makes us think collectively that we, two limbed idiots have evolved to such a greater height of consciousness that we have become any different from the times of Genghis Khan. We display the same casual acceptance of warfare and bloodshed now, as we as a species did, back then.By 1369, all Christians, whether Roman Catholic or Syro-Oriental, were expelled. With the end of Mongol rule in the 14th century, Christianity almost disappeared in mainland Asia, with three of the four principal Mongol khanates embracing Islam. 

Should they be found guilty of each of these crimes?

Why or why not?
