Depending on the context, Manchuria can either refer to a region that falls entirely within the People's Republic of China, or a larger region divided between China and Russia. The region that falls entirely within modern China is now usually referred to as Northeast China in China, although "Manchuria" is widely used outside of China to denote the geographical and historical region. This region is the traditional homeland of the Xianbei, Khitan, and Jurchen (later called Manchu) peoples, who built several states historically, although no term for "Manchuria" exists in the Manchu language, which originally referred to the area as the "Three Eastern Provinces". - Genghis Khan (often pronounced ; c. 1162 August 18, 1227), born Temujin, was the founder and Great Khan (Emperor) of the Mongol Empire, which became the largest contiguous empire in history after his death. - Tolui, (Classic Mongolian: Toluy, Tului, , , Tolui Khan (meaning the Khan Tolui)) (11921232) was the fourth son of Genghis Khan by his chief khatun Borte.

Before that he had served with distinction in the campaigns against the Jin dynasty, the Western Xia and the Khwarezmid Empire, where he was instrumental in the capture and massacre at Merv and Nishapur. He is a direct ancestor of most of the Emperors of Mongolia and the Ilkhanids. - Merv (, "Marv"), formerly Achaemenid Satrapy of Margiana, and later Alexandria () and Antiochia in Margiana, was a major oasis-city in Central Asia, on the historical Silk Road, located near today's Mary in Turkmenistan. - Arpa Ke'un , also known as Arpa Khan or Gavon or Gawon ( died 1336 ) , was an Ilkhan ( 1335 -- 1336 ) during the disintegration of the Mongol state in Persia .

It had an estimated population of 239,185 as of 2011 and its county 433,105. Nearby are the turquoise mines that have supplied the world with turquoise for at least two millennia. The city was founded in the 3rd century by Shapur I as a Sasanian satrapy capital. Nishapur later became the capital of Tahirid dynasty and was reformed by Abdullah Tahir in 830, and was later selected as the capital of Seljuq dynasty by Tughril in 1037. From the Abbasid era to the Mongol invasion of Khwarezmia and Eastern Iran, the city evolved into a significant cultural, commercial, and intellectual center within the Islamic world. Nishapur, along with Merv, Herat and Balkh were one of the four great cities of Greater Khorasan and one of the greatest cities in the middle ages, a seat of governmental power in eastern of caliphate, a dwelling place for diverse ethnic and religious groups, a trading stop on commercial routes from Transoxiana and China, Iraq and Egypt. - Ariq Boke (after 12191266), the components of his name also spelled Arigh, Arik and Bukha, Buka (Chinese: ), was the seventh and youngest son of Tolui, a son of Genghis Khan.

When Kublai returned for an election in 1260, rival factions could not agree, and elected both claimants, Kublai and Ariq Boke, to the throne, resulting in the Toluid Civil War that fragmented the Mongol Empire. Ariq Boke was supported by the traditionalists of the Mongol Empire, while his brother Kublai was supported by the senior princes of North China and Manchuria. - The Mongol Empire (Mongolian: "Mongolyn Ezent Guren" ; Mongolian Cyrillic: also ("Horde") in Russian chronicles) existed during the 13th and 14th centuries and was the largest contiguous land empire in history.

The decision by her husband to rescue her may have been one of the key decisions that started him on his path to conquer the world. She gave birth to four sons and five daughters, who, along with their own descendants, were the key bloodline which further expanded the Mongol Empire. - Mongolia (Mongolian: ["Monggol Ulus"] in Mongolian script; ["Mongol Uls"] in Mongolian Cyrillic) is a landlocked unitary sovereign state in East Asia.
