Secret History of the Mongols in the context of "Mongolian script"

Oirats (/ˈɔɪræt/; Mongolian: Ойрад [ˈɞe̯ɾə̆t]) or Oirds (Mongolian: Ойрд [ˈɞe̯ɾə̆t]; Kalmyk: Өөрд [ˈøːɾə̆t]), formerly known as Eluts and Eleuths (/ɪˈluːt/ or /ɪˈljuːθ/; Chinese: 厄魯特, Èlǔtè) are the westernmost group of Mongols, whose ancestral home is in the Altai region of Siberia, Xinjiang and western Mongolia.

The first documented reference to Elut and Yelut was in the Onginsk "rune" inscriptions dated in the sixth century. The dating of the Oirats to the 13th century is based on the text of the Secret History of the Mongols. Historically, the Oirats were composed of four major tribes: Dzungar (Choros or Olots), Torghut, Dörbet and Khoshut.

Xingqing Prefecture, also known as Irqai, Äriqaya and Egrigaia in Tangut, Secret History of the Mongols and The Travels of Marco Polo respectively, was the capital of Western Xia (Tangut Empire) between the 11th and 13th centuries and its de facto independent precursor Dingnan Jiedushi, in modern Ningxia, China, centering on modern Yinchuan.

After the fall of the Tangut Empire, it was absorbed into imperial China. The Mongol leader and conqueror Genghis Khan, who founded the Mongol Empire, died there on 25 August 1227.

Hö'elün (Mongolian: ᠥᠭᠡᠯᠦᠨ ᠦᠵᠢᠨ, Ö’elün Üjin, lit. 'Lady Ö’elün'; fl. 1162–1210) was a noblewoman of the Mongol Empire and the mother of Temüjin, better known as Genghis Khan. She played a major role in his rise to power, as described in the Secret History of the Mongols.

Born into the Olkhonud clan of the Onggirat tribe, Hö'elün was originally married to Chiledu, a Merkit aristocrat; she was captured shortly after her wedding by Yesügei, an important member of the Mongols, who abducted her to be his primary wife. She and Yesügei had four sons and one daughter: Temüjin, Qasar, Hachiun, Temüge, and Temülen. After Yesügei was fatally poisoned and the Mongols abandoned her family, Hö'elün shepherded all her children through poverty to adulthood—her resilience and organisational skills have been remarked upon by historians. She continued to play an important role after Temüjin's marriage to Börte—together, the two women managed his camp and provided him with advice.

Toghrul (Mongolian: Тоорил хан Tooril han; Chinese: 脫里), also known as Wang Khan or Ong Khan (Ван хан Wan han; Chinese: 王汗; pinyin: Wáng Hán; died 1203), was a khan of the Keraites. He was the blood brother (anda) of the Mongol chief Yesugei and served as an important early patron and ally to Yesugei's son Temüjin, later known as Genghis Khan. The main source on his life is the Secret History of the Mongols.

The Baljuna Covenant was an oath sworn in mid-1203 AD by Temüjin—the khan of the Mongol tribe and the future Genghis Khan—and a small group of companions, subsequently known as the Baljunatu. Temüjin had risen in power in the service of the Kereit khan Toghrul during the late 12th century. In early 1203, Toghrul was convinced by his son Senggum that Temüjin's proposal of a marriage alliance between his and their families was an attempt to usurp their power. After escaping two successive Kereit ambushes, Temüjin was cornered and comprehensively defeated at the Battle of Qalaqaljid Sands.

Temüjin regrouped the scattered remnants of his forces and retreated to Baljuna, an unidentified river or lake in south-eastern Mongolia. There, he and his closest companions swore an oath of mutual fidelity, promising to share hardships and glories. Having spent the summer recruiting warriors attracted by the ideals of his campaign, Temüjin amassed enough of a force to defeat the Kereit in battle that autumn. Three years later in 1206, having defeated all enemies on the steppe, Temüjin entitled himself Genghis Khan at a kurultai and honoured the Baljunatu with the highest distinctions of his new Mongol Empire. Nineteenth-century historians doubted the episode's historicity because of its omission (probably on account of the heterogeneity of the oath-swearers) from the Secret History of the Mongols, a 13th-century epic poem recounting Temüjin's rise.

The Tuul River or Tula River (/ˈtuːl/; Mongolian: Туул гол, Tuul gol, pronounced [ˈtʰʊːɮ ɢɔɮ]; in older sources also Tola) is a river in central and northern Mongolia. Sacred to the Mongols, the Tuul is generally called the Hatan Tuul (Mongolian: Хатан Туул, [ˈχaʰtəɴ tʰʊːɮ]; lit. "Queen Tuul"). It is 882.8 kilometres or 549 miles long and drains an area of 49,840 square kilometres or 19,240 square miles. The Secret History of the Mongols (1240 AD) frequently mentions a "Black Forest of the Tuul River" where the palace of Ong Khan was located.

The river originates in the Khan Khentii Strictly Protected Area in the Khentii Mountains, in the Erdene sum of Töv aimag.From there, it travels southwest until it reaches the territory of Ulaanbaatar. Its water runs through the southern part of the capital city of Mongolia, continuing in a western direction in large loops. When it meets the border of Bulgan aimag it turns north, running along that border. After it enters Selenge aimag, it discharges into the Orkhon River near the sum center of Orkhontuul sum.

Shigi Qutuqu (Mongolian: ᠰᠢᠭᠢᠬᠤᠲᠤᠭ; c. 1178–1260) was a high-ranking official during the early decades of the Mongol Empire. The adopted son of the empire's founder Temüjin (later entitled Genghis Khan) and his wife Börte, Shigi Qutuqu played an important role in the codification of Mongol law, serving with distinction as an administrator in North China. He may also have been a major source for the Secret History of the Mongols, which portrays him very favourably.

Although the Secret History states that Shigi Qutuqu was adopted by Hö'elün, Temüjin's mother, chronological inconsistencies make this account improbable. The foundling was brought up in Temüjin's household and was one of the first Mongols to become literate. The Secret History exaggerates his role in the years after the empire's foundation, but Shigi Qutuqu was nevertheless appointed to several high-ranking legal positions, in which he served during the Mongol conquest of the Jin dynasty. He was the commander during the only Mongol defeat of the western campaign against Khwarazmia, being overcome by Jalal al-Din at the 1221 Battle of Parwan.
