Batu (Mongolian: ᠪᠠᠲᠣ, transliteration: Batu, secret history: Batu, Cyrillic alphabet: Бат, 1208–1255), grandson of Temujin, second son of Shuchi, was born to Wuqi Zhenkedun, daughter of Hongji Rabu Chennayan. Founder of the Mongol Khanate of Chincha. The Mongols, because of his leniency toward his subordinates, called him Sayin Khan (meaning "Khan of Charity").

Battu, the second son of Shuchi. He was friendly with his brother Orda, and Orda knew that he was not as good as Battu, but gave way to Battu, and Hui Chijin decided to make Badu his heir. When Genghis Khan died, Batu and his brother Orda, brothers Berlek, Timur, Xiban, Tangute, and Berlekchar came to be buried, and Emperor Taizong's wokoutai was the Khan's throne (New Yuan History, vol. 107).
Genghis Khan extended haibala to parts of present-day Uzbekistan and Turkmenistan in the areas of present-day Kopal and Khwarazm to sakhasin in the lower Volga River and near the border area of the bugarian state of present-day Kazan, and gave it to Shuchi, who after his death in 1227, was inherited by Battu.
Genghis Khan ordered Subutai and Zhebei to march west from 1221 to 1223, because they could not fully attack Chincha, Kievan Rus', Eastern Europe, etc. In 1235, Wokoutai heeded the advice of his second brother Chagatai and decided that Batu, Buli (the second son of Chagatai's second son Mu Er bald gan), Guiyu (the eldest son of Wokoutai), and Möngke (the eldest son of Torre), as the backup of Subutai, assisted the raiders, and the Kyrgyz, North Caucasians, Chincha, Kievan Rus' and the Kingdom of Poland were the second western expedition for Mongolia. Wokoutai surrendered to badu as the head of all the princes who went out on these expeditions, and Guiyu was the head of the Mongol homeland, and on this expedition, all the patriarchs in charge of the state should send their eldest sons to the west from among their sons, and the kings who did not control the state, each of them had to send their eldest son to the west, and every household, a thousand households, a hundred households, ten husbands, etc., no matter who they were, they had to send their eldest son to the west, and the princess and the horse must also send the eldest son to the west in accordance with this regulation, so it is also called the "first son's western expedition".
Wokoutai said: The method of sending the eldest sons to go out on the expedition was conceived by Chagatai, chagatai once sent people to say that they should give subutai additional support, and that the eldest sons would go out on a western expedition with more troops, and once the army was more powerful, it would be easier to advance, and the enemy over there was many countries, and the other side was a very tough people, and I heard that if they were angry, they could use their own blades to hack their own people to death, and they heard that they had a lot of sharp weapons on their side (Mongolian Secret History verse 270).
After the western expedition team attacked the city of Scorn gexi, they were about to leave for a parting banquet, and All said: I am a little older than these princes, drink one or two glasses of wine first, causing dissatisfaction from Buli and Guiyu to leave the banquet and leave on horseback, and before leaving, they said: Batu is the same as all of us, how can we drink first, and disperse without joy, Batu reports this matter to Wokoutai, who expresses justice in handling this matter, reprimands Guiyu and informs Chagatai of this matter, and Chagatai himself handles it, and says that everything in the wild is decided by Batu, and the knot between Guiyu and Batu begins It may also be because Battu's father is not sure if there is blood from the Golden Family.
From 1235 to 1241, Battus led an army to conquer the above-mentioned countries, including the Chincha, volga Bulgaria, Kievan Rus', Galicia, Moldavia, the Grand Duchy of Lithuania, the Kingdom of Poland (then translated as "Borre"), the Kingdom of Hungary, the Second Bulgarian Empire, Bohemia and the Czech Republic, Moravia and Slovakia, Laska, the Republic of Venice, and defeated the Germanic-Polish alliance led by Henrik II, Duke of Silesia, and successively defeated the Germanic-Polish alliance led by Henrik II, Duke of Silesia. Bohemia) and the Hungarian army led by King Bella IV of Hungary swept through Eastern and Central Europe, destroying and slaughtering thirty towns, including Kiev and Budapest. However, when the Mongol army attempted to continue its march on Dalmatia in the Republic of Venice, it received news of the death of Wokoutai Khan and led the army to retreat east.
In 1242, the capital was established in Saray of Chincha on the lower volga river, and the state was officially established, known as the Golden Horde. At that time, it was recorded as the Mongolian "Ulus of Jochi" (Ulus is the meaning of the state), because a large number of Chincha people were residents of the khanate, and even became the backbone of the khanate, so it was called "Chincha Khanate".
Battus administered Eastern Russia with the assistance of the Grand Duke of Russia. In 1242, Yaroslav II, Grand Duke of Vladimir, met with Batu and received a canon, which was a method of administering Eastern Russia, which later became custom; as for Western Russia, Battus ordered Daniel, Grand Duke of Galicia, to hand over power to a Mongol general and bring it under Mongol jurisdiction.
After Battus' death, he first passed on the throne to his son Sarita, and when Sarita died, Möngke nominated the young king Uraza to replace him, and batu's widow, Borakjin, oversaw the kingdom (she was an Alechitatar). In 1257, his younger brother Bergo succeeded to the throne as Khan of the Golden Horde.
