Batu Khan
Batu Khan was a Mongol ruler and founder of the Golden Horde, a constituent of the Mongol Empire established after Genghis Khan's demise. Batu was a son of Jochi, thus a grandson of Genghis Khan. His ulus ruled over the Kievan Rus', Volga Bulgaria, Cumania, and the Caucasus for around 250 years.
Personality and appearance
According to Giovanni da Pian del Carpine, Batu was "kind enough to his own people, but he is greatly feared by them. He is, however, most cruel in fight; he is very shrewd and extremely crafty in warfare, for he has been waging war for a long time." He received the nickname of сайн, by which he was referred to by Marco Polo. William of Rubruck described him as about the height of his lord John de Beaumont and as having his entire face covered with reddish spots.Early years
After his son Jochi's death, Genghis Khan assigned Jochi's appanages to his sons. The Great Khan installed Batu as Khan of the Golden Horde. Jochi's eldest son, Orda Khan, also agreed that Batu should succeed their father. Genghis Khan's youngest brother Temüge attended the coronation ceremony as an official representative of Genghis. When Genghis Khan died in 1227, he left 4,000 Mongol men to Jochi's family. Jochi's lands were divided between Batu and his older brother Orda. Orda's White Horde ruled the lands roughly between the Volga river and Lake Balkhash, while Batu's Golden Horde ruled the lands west of the Volga.In 1229, Ögedei dispatched three tumens under Kukhdei, Sundei and Humpdei to conquer the tribes on the lower Ural River. According to Abulghazi, Batu joined Ögedei's military campaign against the Jin dynasty in North China while his younger brother was fighting the Bashkirs, the Cumans, the Bulghars and the Alans in the west. Despite heavy resistance from their enemies, the Mongols conquered major cities of the Jurchens and made the Bashkirs their ally. In the 1230s, Ögedei distributed lands in Shanxi to Batu and the family of Jochi, but they appointed their officials under the supervision of the Imperial governor, and likewise in Khorasan.
Conquest of Kievan Rus'
At the kurultai in Mongolia after the end of the Mongol-Jin War, the Great Khan Ögedei ordered Batu to conquer western nations. In 1235 Batu, who earlier had directed the conquest of the Crimean Peninsula, was assigned an army of possibly 130,000 to oversee an invasion of Europe. His relatives and cousins Güyük, Büri, Möngke, Khulgen, Khadan, Baidar and notable Mongol generals Subutai, Borolday, and Mengguser joined him by the order of his uncle Ögedei. The army, actually commanded by Subutai, crossed the Volga and invaded Volga Bulgaria in 1236. It took them a year to extinguish the resistance of the Volga Bulgarians, Kypchaks, and Alani.In November 1237 Batu Khan sent his envoys to the court of Yuri II of Vladimir-Suzdal and demanded his allegiance. When Yuri refused to surrender the Mongols besieged Ryazan. After six days of bloody battle, the city was totally annihilated and never restored to its former glory. Alarmed by the news, Yuri II sent his sons to detain the horde, but they were soundly defeated. Having burnt Kolomna and Moscow, the horde laid siege to the capital of Vladimir-Suzdal on 4 February 1238. Three days later the city was taken and burnt to the ground. The royal family perished in the fire, while the grand prince hastily retreated northward. Crossing the Volga, he mustered a new army, which was totally exterminated by the Mongols on the Sit' River on 4 March.
Thereupon Batu Khan divided his army into smaller units, which ransacked fourteen Rus' cities: Rostov, Uglich, Yaroslavl, Kostroma, Kashin, Ksnyatin, Gorodets, Galich, Pereslavl-Zalessky, Yuriev-Polsky, Dmitrov, Volokolamsk, Tver, and Torzhok. The most difficult to take was the small town of Kozelsk, whose boy-prince Titus and inhabitants resisted the Mongols for seven weeks. As the legend goes, at the news of Mongol approach, the city of Kitezh was submerged in a lake with all its inhabitants. Khadan and Buri stormed the city in three days after they joined Batu. The only major cities to escape destruction were Smolensk, which submitted to the Mongols and agreed to pay tribute, and Novgorod with Pskov, which could not be reached by the Mongols on account of considerable distance and the intervening marshlands.
When Batu drank a cup of wine before the others at the victory banquet, Büri complained of the unfairness of Batu receiving such a vast and fertile steppe, and the Mongol army, along with Güyük and others, ridiculed Batu as an "old woman with a beard". They then left the banquet. Batu sent an envoy to his uncle Ögedei to complain of his cousins' rude behavior. Ögedei got angry on hearing the news and recalled Buri and Güyük. According to some sources, Buri, who was sent to his grandfather Chagatai, never returned to join the Mongol conquest of Europe; Güyük returned to the Russian steppe after his father Ögedei harshly criticized him.
In the summer of 1238, Batu Khan devastated the Crimea and pacified Mordovia and the Kipchak-controlled steppe. In the winter of 1239, he sacked Chernigov and Pereyaslav. After several days of siege, the Mongols stormed Kiev in December 1240. Despite fierce resistance by Danylo of Halych, Batu Khan managed to take the two principal capitals of his land, Halych and Volodymyr. Ruthenian principalities became vassals of the Mongol Empire.
Invasion of Central Europe
The Cuman refugees took shelter in the Kingdom of Hungary. Batu sent at least five messengers to Béla IV, the King of Hungary, but they were all killed. For the last time Batu demanded that Bela have the Cumans returned and warned: "It is much easier for the Cumans to escape than it is for you...you dwell in houses and have fixed towns and fortresses, so how will you escape me?" Batu Khan then decided to "reach the ultimate sea", where the Mongols could proceed no further. Some modern historians speculate that Batu intended primarily to assure his flanks were safe for the future from possible interference from the Europeans, and partially as a precursor to further conquest. Most believe he intended the conquest of all Europe, as soon as his flanks were safe and his forces ready.File:Tatarsinvade.jpg|thumb|left|Béla IV flees from Mohi, detail from Chronicon Pictum
Having devastated the various Rus' principalities, Subutai and Batu sent spies into Poland, Hungary, and as far as Austria in preparation for an attack into the heartland of Europe. With a clear picture of the European kingdoms, they brilliantly prepared an attack. Batu Khan was the overall leader, but Subutai was the actual commander in the field and as such was present in both the northern and southern campaigns against Rus'. The Mongols invaded central Europe in three groups. One group invaded and devastated Poland, defeating a combined force under Henry II the Pious, Duke of Silesia and the Grand Master of the Teutonic Order at Legnica. A second crossed the Carpathian Mountains, and a third followed the Danube. The armies swept the plains of Hungary over the summer, and in the spring of 1242 they regained impetus and extended their control into Austria and Dalmatia, as well as invading Morava.
While the northern force under Ögedei's son Khadan and Baidar, the son of Chagatai, won the Battle of Legnica, and another army of Güyük or Büri triumphed in Transylvania, Subutai was waiting for another victory over the Magyars, the Croats, and the Templars on the Hungarian plain. In 1241, a Tatar army led by Bujek crossed the mountains of the Kara Ulagh ; Bujek defeated the Vlachs and one of their leader named Mišlav. However, the Mongol Army was defeated by Ivan Asen II of the Second Bulgarian Empire shortly afterward. After the siege of Pest, Batu's army withdrew to the Sajo River and inflicted a tremendous defeat on King Béla IV and his allies at the Battle of Mohi on 11 April. Khadan, Baidar, and Orda went to Hungary, devastating Moravia en route. The Mongols appointed a darughachi in Hungary and minted coins in the name of the Khagan. The country of Béla was assigned to Orda by Batu as an appanage; Batu sent Khadan in pursuit of Béla, who retreated to Croatia.
The Mongol battalions checked the forces of the Holy Roman Empire and Babenberg Austria. During his campaign in Central Europe, Batu demanded that Frederick II, the Holy Roman Emperor, dethrone himself, and said: "I am coming to usurp your throne instead of you". The latter only replied that he would make a good falconer, for he understood birds very well. The Emperor and Pope Gregory IX called for a crusade against the Mongol Empire, but Europe was plagued by internal strife. Subutai achieved lasting fame with his victories in Europe, as he had in Eastern Persia.
By late 1241, Batu and Subutai were finalizing plans to invade Austria, Italy, and Germany when the news came of the death of Ögedei Khan, who died in December 1241. Batu wanted to continue the war, but Subutai reminded him of the law of Yassa. The Mongols withdrew in late spring of 1242, as the Princes of the Blood, and Subutai, were recalled to Karakorum where the kurultai was held. Batu was a potential Great Khan, but when he failed to gain the title he turned to consolidate his conquests in Asia and the Urals.
Viceroy and struggle with Güyük
Withdrawing from Hungary, Batu made his camps along the banks of the Volga. When the Great Khatun Töregene invited him to elect the next Emperor of the Mongol Empire, Batu announced his inability to attend any immediate kurultai, thus delaying the succession for several years. Eventually, Güyük was elected Khagan in 1246, with Batu's brothers representing the Jochid lineage. As one of the oldest members of Chingisid Borjigin, Batu became a viceroy over all the western parts of the empire, controlling routine affairs among the Rus' princes, nominating Jochid retainers as governors of Iran, and receiving in audience grandees from the Caucasus. At no point, however, did he openly challenge the authority of the Great Khan.During the absence of Batu, the Mongols who were left behind put to death Mstislav, the prince of Rylsk, in Kievan Rus'. On his return Batu summoned the Grand prince Yaroslav II of Vladimir to meet him. Yaroslav was well received by Batu, who confirmed him as suzerain over the other Rus' princes, and gave him authority of Kiev. The princes of Suzdal followed Yaroslav's example. Batu sent Yaroslav to the imperial court of Karakorum to assist at the inauguration of Güyük Khan in 1246. Plano Carpini, who got approval from Batu to go further, noted that the Great Khan's aunt was executed. At the same time Yaroslav was poisoned in Mongolia.
File:SmirnovVS KnMihailChern.jpg|thumb|left|Prince Michael of Chernigov was passed between fires in accordance with ancient Turco-Mongol tradition. Batu Khan stabbed him to death for his refusal to do obeisance to Genghis Khan's shrine in the pagan ritual.
Batu had commissaries in the various towns where the dependent Rus' princes and other princes held their courts. The princes from Rus' principalities such as Vladimir Constantine, Boris, Gleb, Vasili, Constatantine, Vladimir Constantinovich, Vasil'ko and Sviatoslav Vsevolodovich of Vladimir, went to the court of Batu in person. When Michael of Chernigov, who had murdered the Mongol envoy in Kiev, arrived, the Mongol overseers were engaged in taking a census of the inhabitants for the poll tax. Michael was ordered to repair to Batu. When summoned before Batu, he was made to pass between two fires and ordered to prostrate himself before the tablets of Genghis Khan. According to the hagiographic vita written in praise of him decades later, Michael replied that he did not object to do obeisance to Batu himself, but to adore images of a dead man was repugnant. As he persisted in his refusal, Batu ordered his death.
Danylo of Halych was summoned to Batu in Sarai, and submitted himself to the Mongols, an act later decried in the Galician-Volhynian Chronicle, which otherwise glorified Danylo's exploits. Batu, addressing him, said "You have for a long time refused to come, but have effaced your ill conduct by your obedience" and saluted him with a draught of airag. They exchanged hostages whereby 100 families of Keraites were re-settled in Carpathian-Galicia. After the defeat of the Sultanate of Rum, Baiju freed David VII Ulu from Turkish imprisonment and sent him to Batu and Güyük. Fearing Baiju's aggressive policy, Queen Rusudan of Georgia sent her son David VI Narin to Batu's court to get official recognition as heir apparent. Batu supported David VI and granted him the rights above the Georgian and Armenian nobles and the Mongol tammachis. But Güyük made David Ulu the senior king of Georgia and ordered Batu's protege David Narin to be subordinate to David Ulu.
Suspicion between Batu and Güyük increased, and Güyük replaced the officials in Iran and the Caucasus with his own men, including Eljigidei. When Güyük began moving west, Sorghaghtani Beki, the widow of Tolui, warned Batu that he was actually the Great Khan's target. When Güyük summoned Batu to appear before him, Batu moved slowly. Before meeting Batu, Güyük died suddenly. According to William of Rubruck and a Muslim chronicle, one of Batu's brothers murdered or poisoned the Great Khan Güyük and Batu then killed the imperial envoy, though this account is not completely confirmed by other major sources.
