Amir Sultan was captured by which Turco-Mongol conqueror?
Amir Sultan Amir Sultan (1368–1429) was Amir Kulal Shamsuddin’s grandson. He was invited by the Ottoman Sultan Bayezid I to Anatolia. Bayezid I had a daughter from his marriage with Daulat Khatun (Devlet Hatun) who was married to Amir Sultan. Daulat Khatun (Devlet Hatun) was a descendant of Jalal ud-Din Rumi. By the end of fourteenth century Timur and Bayezid I had emerged as two superpowers in Asia and Europe, making the confrontation between two a matter of time. Timur took the lead and conquered the Ottoman city of Sivas, disseminating the local population in his trademark style. At the same time two princes, Ahmad Jalair (Ahmad (Jalayirids)) and Kara Yosuf (Qara Yusuf) sought for protection at Bayezid I's court. Their territories had been conquered by Timur. Timur sent two embassies demanding surrender of the two princes, but Bayezid I refused. Bayezid I went a step further and prepared for an attack on Timur’s territory. At this point his son-in-law Amir Sultan advised him against the move knowing well the penchant and proficiency of Timur and his soldiers in a battlefield. However, his genteel council fell on deaf ears. Instigated and incited by the two princes Bayezid I seized Erzurum which was under Timur’s rule. To Timur this was declaration of war and in his symbolic manner he started conquering Ottoman cities one by one with whirlwind speed. Bayezid I took his army to stop Timur and the two goliaths met at the plains of Angora on 20 July 1401 (804AH). Although Bayezid I had made a fierce reputation in Europe as a brilliant general and ferocious warrior but he was no match for Timur whose years in battlefield far exceeded Bayazid’s age. The Mongol attack was ruthless and merciless and in one word, Timur “annihilated” the Ottoman army, taking Bayezid I, his children and princes as captives.
Battle of the Sit River The Battle of the Sit River was fought in the northern part of the present-day Sonkovsky District of Tver Oblast of Russia, close to the selo of Bozhonka, on March 4, 1238 between the Mongol Hordes of Batu Khan and the Rus' under Grand Prince Yuri II of Vladimir-Suzdal during the Mongol invasion of Rus. After the Mongols sacked his capital of Vladimir, Yuri fled across the Volga northward, to Yaroslavl, where he hastily mustered an army. He and his brothers then turned back toward Vladimir in hopes of relieving the city before the Mongols took it, but they were too late. Yuri sent out a force of 3,000 men under Dorozh to scout out where the Mongols were; whereupon Dorozh returned saying that Yuri and his force was already surrounded. As he tried to muster his forces, he was attacked by the Mongol force under Burundai and fled but was overtaken on the Sit River and died there along with his nephew, Prince Vsevolod of Yaroslavl. The battle marked the end of unified resistance to the Mongols and inaugurated two centuries of the Mongol domination of modern day-Russia and Ukraine
