context_page_description: Genghis Khan, also officially Genghis Huangdi, was the founder and first Great Khan and Emperor of the Mongol Empire, which became the largest contiguous empire in history after his death. He came to power by uniting many of the nomadic tribes of Northeast Asia. After founding the Empire and being proclaimed Genghis Khan, he launched the Mongol invasions that conquered most of Eurasia, reaching as far west as Poland and the Levant in the Middle East. Campaigns initiated in his lifetime include those against the Qara Khitai, Khwarezmia, and the Western Xia and Jin dynasties, and raids into Medieval Georgia, the Kievan Rus', and Volga Bulgaria. These campaigns were often accompanied by large-scale massacres of the civilian populations, especially in the Khwarazmian- and Western Xia–controlled lands. Because of this brutality, which left millions dead, he is considered by many to have been a brutal ruler. By the end of his life, the Mongol Empire occupied a substantial portion of Central Asia and China. Due to his exceptional military successes, Genghis Khan is often considered to be the greatest conqueror of all time.
context_section_description: In the early 13th century, the Khwarazmian dynasty was governed by Shah Ala ad-Din Muhammad. Genghis Khan saw the potential advantage in Khwarazmia as a commercial trading partner using the Silk Road, and he initially sent a 500-man caravan to establish official trade ties with the empire. Chinggis and his family and commanders invested in the caravan gold, silver, silk, various kinds of textiles and fabrics and pelts to trade with the Muslim traders in the Khwarazmian lands. However, Inalchuq, the governor of the Khwarazmian city of Otrar, attacked the caravan, claiming that the caravan contained spies and therefore was a conspiracy against Khwarazmia. The situation became further complicated because the governor later refused to make repayments for the looting of the caravans and hand over the perpetrators. Genghis Khan then sent a second group of three ambassadors (two Mongols and a Muslim) to meet the Shah himself, instead of the governor Inalchuq. The Shah had all the men shaved and the Muslim beheaded and sent his head back with the two remaining ambassadors. Outraged, Genghis Khan planned one of his largest invasion campaigns by organizing together around 100,000 soldiers (10 tumens), his most capable generals and some of his sons. He left a commander and number of troops in China, designated his successors to be his family members and likely appointed Ögedei to be his immediate successor and then went out to Khwarazmia.
  The Mongol army under Genghis Khan, generals and his sons crossed the Tien Shan mountains by entering the area controlled by the Khwarazmian Empire. After compiling intelligence from many sources Genghis Khan carefully prepared his army, which was divided into three groups. His son Jochi led the first division into the northeast of Khwarazmia. The second division under Jebe marched secretly to the southeast part of Khwarazmia to form, with the first division, a pincer attack on Samarkand. The third division under Genghis Khan and Tolui marched to the northwest and attacked Khwarazmia from that direction.
  The Shah's army was split by diverse internecine feuds and by the Shah's decision to divide his army into small groups concentrated in various cities. This fragmentation was decisive in Khwarazmia's defeats, as it allowed the Mongols, although exhausted from the long journey, to immediately set about defeating small fractions of the Khwarazmian forces instead of facing a unified defense. The Mongol army quickly seized the town of Otrar, relying on superior strategy and tactics. Genghis Khan ordered the wholesale massacre of many of the civilians, enslaved the rest of the population and executed Inalchuq by pouring molten silver into his ears and eyes, as retribution for his actions. Near the end of the battle the Shah fled rather than surrender. Genghis Khan ordered Subutai and Jebe to hunt him down, giving them 20,000 men and two years to do this. The Shah died under mysterious circumstances on a small island within his empire.
  The Mongols' conquest, even by their own standards, was brutal. After the capital Samarkand fell, the capital was moved to Bukhara by the remaining men, while Genghis Khan ordered two of his generals and their forces to completely destroy the remnants of the Khwarazmian Empire, including not only royal buildings, but entire towns, populations, and even vast swaths of farmland.
  The Mongols attacked Samarkand using captured enemies as body shields. After several days only a few remaining soldiers, loyal supporters of the Shah, held out in the citadel. After the fortress fell, Genghis supposedly reneged on his surrender terms and executed every soldier that had taken arms against him at Samarkand. The people of Samarkand were ordered to evacuate and assemble in a plain outside the city, where they were killed and pyramids of severed heads raised as a symbol of victory. Ata-Malik Juvayni, a high official in the service of the Mongol empire, wrote that in Termez, on the Oxus, "all the people, both men and women, were driven out onto the plain, and divided in accordance with the
