Chagatai Khan
Chagatai Khan ("TsagadaiChágětáiJoghatai"; 22 December 1183 – 1 July 1242) was the second son of Genghis Khan.
He was Khan of the Chagatai Khanate from 1226-1242 C.E.
The Chagatai language and Chagatai Turks take their names from him.
He inherited most of what are now the five Central Asian states after the death of his father.
He was also appointed by Genghis Khan to oversee the execution of the Yassa, the written code of law created by Genghis Khan, though that lasted only until Genghis Khan was crowned Khan of the Mongol Empire.
The Empire later came to be known as the Chagatai Khanate, a descendant empire of the Mongol Empire.
Chagatai Khan was considered hot-headed and somewhat temperamental by his relatives, because of his attitude of non-acceptance of Jochi as Great Khan.
He was the most vocal about this issue among his relations.
Chagatai is in some stories held responsible for the death of Jochi and Genghis Khan.
At any rate, he was animated by the soldier-like spirit of his father, and succeeded in keeping order among as heterogeneous a population as a kingdom was ever composed of.

He participated in the European campaign ("The elder boys campaign" as it was known in Mongolia) with his nephew Büri from 1235-1241.
He commanded the Mongol army assigned to Poland with Kadan and, probably, Orda Khan.
Baidar defeated many Poles, Russians, Germans and Moravians.
On 13 February 1241 the Mongols crossed the frozen Vistula.
The town of Sandomierz was taken and plundered.
Further to the west, on 18 March Orda and Baidar met the Polish army under the command of Duke Bolesław V (not present at the battle) at the battle of Chmielnik.
The Poles were heavily defeated and Boleslaw with a part of his troops fled to Moravia.
On 22 March the Mongols stood before Kraków, many of whose inhabitants had already made their escape.
On Palm Sunday the Mongols set the town on fire and took prisoner large numbers of the people who had remained.
Moving further west, Orda and Baidar reached a place east of Opole, where they forced Duke Mieszko the Fat's army to retreat.
Near Racibórz they crossed the Oder.
Racibórz was burnt by its inhabitants when they left the town.
Wrocław fell into the hands of the Mongols, although the citadel itself did not surrender.
Their first assault against the fortress having failed, the Mongols wasted no time on a siege.
They bypassed the citadel and pushed forward to the west.
After defeating a combined force of Poles, Czechs, and Templars at Liegnica (see Battle of Legnica), Baidar camped for about two weeks in the neighbourhood of Otmuchów (between Opole and Kłodzko).
Early in May 1241 they entered Moravia.
Then continued via Brno, to join Batu Khan's main army in Hungary.
Although Bohemia remained unmolested, Moravia had much to endure.
The destruction in Poland, Silesia and Moravia was all much of the same kind.
Baidar participated in the election of Güyük Khan in 1247.
