Genghis Khan insults Emperor Wanyan Yongji (known in traditional histories as Prince Shao of Wei) by publicly stating in 1210 that he is a coward and unfit to be a leader.

Genghis adds, "The emperor should be a man from sky like me."

Soon, news spreads to the Jin emperor through a Jin officer.

The Jin emperor is enraged and orders the execution of the Mongolian ambassador.

Liang Kai had worked as an academic painter in his early years, but leaves the Song academy for a Chan Buddhist monastery at the peak of his career.

Called Crazy Liang because of his eccentric personality, he develops a more subjective and intuitive approach to painting than that of the contemporary academic school.

The highly influential Liang executes a celebrated monochrome ink painting, the Huineng Chopping Bamboo, in the qianbi or abbreviated style.

He dies in about 1210.

The walls of Yinchuan are by January 1210 nearly breached.

However, the dike used to divert the river breaks, and the ensuing flood wipes out the Mongol camp, forcing the Mongols to take higher ground.

Despite this setback, the Mongols still pose a threat to Western Xia, and with the state's crops destroyed and no relief coming from the Jin, Li Anquan agrees to submit to Mongol rule, demonstrating his loyalty by giving a daughter, Chaka, in marriage to Genghis and paying a tribute of camels, falcons, and textiles.

Western Xia attacks the Jin dynasty later in the year, ending years of peace between the two countries, as punishment for their refusal to aid them against the Mongols.

Muhammad II, the Khwarezm-Shah, takes Samarkand in 1210 after the Kara-Khitans retreat to deal with the rebellion from the Naiman Kuchlug, who had seized the Kara-Khitans' treasury at Uzgen.

The Khwarezm-Shah defeats the Kara-Khitans near Talas.

Muhammad and Kuchlug had, apparently, agreed to divide up the Kara-Khitan's empire.

Genghis Khan’s son eldest son, Jochi, had in 1207 successfully conquered the forest peoples in Siberia, extending the northern border of the Mongol Empire for the very first time.

On behalf of his father, Jochi leads a campaigns against the Kyrgyz in 1210.

The Battle of Ümera, recorded by Henry of Livonia, is fought near Cēsis (Estonian: Võnnu) on the Ümera river in 1210, during the Livonian Crusade between Estonians and Crusaders.

The Estonians win the battle, in which Bertold, the son of Estonian leader Lembitu of Lehola, is killed.

Aibak dies accidentally in 1210 while he is playing a game of polo in Lahore on horseback: his horse falls and he is impaled on the pommel of his saddle.

He is buried near the Anarkali bazaar in Lahore.

Francis is soon joined by a prominent fellow townsman, Bernardo di Quintavalle, who contributes all that he has to the work, and by other companions, who are said to have reached the number of eleven within a year.

The brothers live in the deserted lazar-house of Rivo Torto near Assisi; but they spend much of their time traveling through the mountainous districts of Umbria, always cheerful and full of songs, yet making a deep impression on their hearers by their earnest exhortations.

Their life is extremely ascetic, though such practices are apparently not prescribed by the first rule which Francis has given them (probably as early as 1209), which seems to have been nothing more than a collection of Scriptural passages emphasizing the duty of poverty.

Soon attracting followers, Francis preaches the necessity of a poor, simple lifestyle based on the ideals of the Gospels.

In spite of some similarities between this principle and some of the fundamental ideas of the Waldensians, the brotherhood of Assisi succeeds in gaining the approval of Pope Innocent III.

What seems to have impressed first the Bishop of Assisi, Guido, then Cardinal Giovanni di San Paolo and finally Innocent himself, is their utter loyalty to the Church and the clergy.

In approval, Pope Innocent III grants Francis and his disciples permission to preach on moral topics, and has Francis ordained a deacon, allowing him to read Gospels in the church.

The followers, who are tonsured, increase, called by Francis friars minor—the lesser brethren.

Innocent probably sees in them a possible answer to his desire for an orthodox preaching force to counter heresy.

Many legends have clustered around the decisive audience of Francis with the Pope.

The realistic account in Matthew Paris, according to which the Pope originally sent the shabby saint off to keep swine, and only recognized his real worth by his ready obedience, has, in spite of its improbability, a certain historical interest, since it shows the natural antipathy of the older Benedictine monasticism to the plebeian mendicant orders.

Otto, immediately breaking the promise made at Speyer to Innocent, invades the Sicilian lands of the young Frederick, for whom the pope is regent and feudal overlord.

Otto’s seizure of papal territory results in his excommunication by the pope.
