Börte in the context of "Mongolian script"

Genghis Khan (born Temüjin; c. 1162 – August 1227), also known as Chinggis Khan, was the founder and first khan of the Mongol Empire. After spending most of his life uniting the Mongol tribes, he launched a series of military campaigns, conquering large parts of China and Central Asia.

Born between 1155 and 1167 and given the name Temüjin, he was the eldest child of Yesugei, a Mongol chieftain of the Borjigin clan, and his wife Hö'elün. When Temüjin was eight, his father died and his family was abandoned by its tribe. Reduced to near-poverty, Temüjin killed his older half-brother to secure his familial position. His charismatic personality helped to attract his first followers and to form alliances with two prominent steppe leaders named Jamukha and Toghrul; they worked together to retrieve Temüjin's newlywed wife Börte, who had been kidnapped by raiders. As his reputation grew, his relationship with Jamukha deteriorated into open warfare. Temüjin was badly defeated in c. 1187, and may have spent the following years as a subject of the Jin dynasty; upon reemerging in 1196, he swiftly began gaining power. Toghrul came to view Temüjin as a threat and launched a surprise attack on him in 1203. Temüjin regrouped and overpowered Toghrul; after defeating the Naiman tribe and executing Jamukha, he was left as the sole ruler on the Mongolian steppe.

Jochi (Mongolian: ᠵᠦᠴᠢ; c. 1182 – c. 1225), also spelled Jüchi, was a prince of the early Mongol Empire. His life was marked by controversy over the circumstances of his birth and culminated in his estrangement from his family. He was nevertheless a prominent military commander and the progenitor of the family who ruled over the khanate of the Golden Horde.

Jochi was the son of Börte, the first wife of the Mongol leader Temüjin, now Genghis Khan. For many months before Jochi's birth, Börte had been a captive of the Merkit tribe, one of whom forcibly married and raped her. Although there was thus considerable doubt over Jochi's parentage, Temüjin considered him his son and treated him accordingly. Many Mongols, most prominently Börte's next son Chagatai, disagreed; these tensions eventually led to both Chagatai and Jochi being excluded from the line of succession to the Mongol throne.

Tolui (c. 1191 – 1232) was the youngest son of Genghis Khan and Börte. A prominent general during the early Mongol conquests, Tolui was a leading candidate to succeed his father after his death in 1227 and ultimately served as regent of the Mongol Empire until the accession of his brother Ögedei two years later. Tolui's wife was Sorghaghtani Beki; their sons included Möngke and Kublai, the fourth and fifth khans of the empire, and Hulagu, the founder of the Ilkhanate.

Tolui was less active than his elder brothers Jochi, Chagatai, and Ögedei during their father's rise to power, but once he reached adulthood he was considered the finest warrior of the four. He commanded armies under his father during the first invasion of Jin China (1211–1215), and his distinguished service during the Mongol invasion of the Khwarazmian Empire secured his reputation. After the fall of the cities of Transoxiana in 1220, Genghis dispatched Tolui early the following year to subjugate the region of Khorasan, which had begun to cause trouble for the Mongol armies. Tolui executed his orders with ruthless efficiency, assaulting the major cities of Merv, Nishapur, and Herat, and subjugating numerous others. Medieval chroniclers attributed more than three million deaths to the massacres he ordered at Nishapur and Merv; while these figures are considered exaggerated by modern historians, they are evidence of the abnormal brutality of Tolui's campaign.

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.

Chagatai Khan (Mongolian: ᠴᠠᠭᠠᠲᠠᠶ; c. 1184 – 1242) was a son of Genghis Khan, a prominent figure in the early Mongol Empire, and the first khan of the Chagatai Khanate. The second son of Genghis's wife Börte, Chagatai was renowned for his masterful knowledge of Mongol custom and law, which he scrupulously obeyed, and his harsh temperament. Because Genghis felt that he was too inflexible in character, most notably never accepting the legitimacy of his elder brother Jochi, he excluded Chagatai from succession to the Mongol throne. He was nevertheless a key figure in ensuring the stability of the empire after Genghis's death and during the reign of his younger brother Ögedei Khan.

Chagatai held military commands alongside his brothers during the Mongol conquest of the Jin dynasty in 1211 and the invasion of the Khwarazmian Empire in 1219. During the latter, he was appointed to a key role in organising logistics in addition to battlefield responsibilities, but was censured after feuding with Jochi during the Siege of Gurganj. After the campaign, Chagatai was granted large tracts of conquered land in Central Asia, which he ruled until his death. He quarrelled with civil officials such as Mahmud Yalavach over matters of jurisdiction and advised Ögedei on questions of rulership. Chagatai died shortly after Ögedei in 1242; his descendants ruled his territories as the eponymous Chagatai Khanate.

The Chinggisids were the descendants of Genghis Khan, also known as Chinggis Khan, and his first wife Börte. The dynasty, which evolved from Genghis Khan's own Borjigin tribe, ruled the Mongol Empire and its successor states. The "Chinggisid principle"—that only descendants of Genghis Khan and Börte could be legitimate rulers of the Mongol or post-Mongol world—would be an important concept for centuries, until the fall of Kazakh Khanate, the last states ruled by Chinggisid monarchs, in 1847.

The Borjigin lineage, descendants of Kaidu, an early Mongol leader, were initially one of many clans inhabiting the Mongol heartland. Genghis Khan was born c. 1162, son of a Borjigit warrior named Yesügei, a member of the Qiyat sub-clan; over the next decades, he subjugated or killed all potential rivals, Borjigit or not. By the time that Genghis established the Mongol Empire in 1206, the only remaining Borjigit were the descendants of Yesügei. They formed the altan uruq (lit. 'Golden Family')—the only people allowed to rule in the empire. Of these, the descendants of Genghis and his first, primary wife Börte held the highest seniority; the Chinggisid Principle was that this particular lineage—the eponymous Chinggisids—were the only legitimate rulers. Mongol religious ideology held that the Chinggisids would eventually become rulers of the entire world.

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.
