Borjigin in the context of "Yuan dynasty"

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.

Dayan Khan (/ˈdaɪən xɑːn/; Mongolian: Даян Хаан [ˈtajɴ ˈχaːɴ]), born Batumöngke (Middle Mongol: [b̥atʰʊ̆møŋkʰĕ], Modern Mongol: [paʰtmɵŋx]; Chinese: 巴圖蒙克 Bātúméngkè; 1472–1517) was a khagan of the Northern Yuan dynasty, reigning from 1480 to 1517. During his rule, he reunited the Mongols under Chinggisid supremacy. His reigning title, "Dayan", means "the whole" or "long lasting" in Mongolian language as he was the longest reigning khagan of the unified Mongols.

Dayan Khan eliminated Oirat and the great Khan of chagatai Altnaa power and abolished the taishi system used by both local and foreign warlords. Dayan Khan's victory at Dalan Tergin reunified the Mongols and solidified their identity as Chinggisid people. His decision to divide the six tumens of Eastern Mongolia as fiefs for his sons created decentralized but stable Borjigin rule over the Mongolian Plateau for a century.

The Yuan dynasty ruled over the Mongolian Plateau, including both Inner and Outer Mongolia as well as part of southern Siberia, between 1271 and 1368. The Mongolian Plateau is where the ruling Mongol Borjigin clan of the Yuan dynasty came from, thus it enjoyed a somewhat special status during the Yuan dynasty, although the capital of the dynasty had been moved from Karakorum to Khanbaliq (modern Beijing) since the beginning of Kublai Khan's reign, and Mongolia had been converted into a regular province, known as the Lingbei Province (Chinese: 嶺北行省), by the early 14th century.

From about 1270 to 1356, the Korean kingdom of Goryeo was ruled by the Mongol Empire and the Mongol-led Yuan dynasty. After the Mongol invasions of Korea and the capitulation of Goryeo in the 13th century, Goryeo became a semi-autonomous vassal state and compulsory ally of the Yuan dynasty for about 80 years. It has been referred to as a "son-in-law kingdom in the Mongol Empire." The ruling line of Goryeo, the House of Wang, was permitted to rule Korea as a vassal of the Yuan, which established the Branch Secretariat for Eastern Campaigns (征東行省; literally "Branch Secretariat for Conquering the East") in Korea as an extension of Mongol supervision and political power. Members of the Goryeo royal family were taken to Khanbaliq, and typically married to spouses from the Yuan imperial clan, the House of Borjigin. As a result, princes who became monarchs of Goryeo during this period were effectively imperial sons in-law (khuregen). Yuan overlordship ended in the 1350s when the Yuan dynasty itself started to crumble and King Gongmin of Goryeo began to push the Yuan garrisons back.

The Timurid Empire was a late medieval, culturally Persianate, Turco-Mongol empire that dominated Greater Iran in the early 15th century, comprising modern-day Iran, Iraq, Afghanistan, much of Central Asia, the South Caucasus, and parts of contemporary Pakistan, North India, and Turkey. The empire had a syncretic culture and combined Turkic, Mongolic, and Persian influences, with the last members of the dynasty being regarded as "ideal Perso-Islamic rulers".

The empire was founded by Timur (Tamerlane), a warlord of Turco-Mongol lineage, who established the empire in 1370 and ruled it until his death in 1405. He saw himself as the great restorer of the Mongol Empire of Genghis Khan, regarding himself as Genghis's heir, and closely associated with the Borjigin. Timur continued to have strong trade relations with Ming China and the Golden Horde, with Chinese diplomats like Ma Huan and Chen Cheng regularly traveling west to Samarkand to conduct trade. The empire led to the Timurid Renaissance, particularly during the reign of astronomer and mathematician Ulugh Begh.

Mongol campaigns in Central Asia occurred after the unification of the Mongol and Turkic tribes on the Mongolian Plateau in 1206. Smaller military operations of the Mongol Empire in Central Asia included the destruction of surviving Merkit and Naimans (which involved forays into Cumania) and the conquest of Qara Khitai. These were followed by a major campaign against Khwarazm. Expansion into Central Asia began in 1209 as Genghis Khan sent an expedition to pursue rivals who had fled to the region and threatened his new empire. The Uyghur kingdom Qocho and leaders of the Karluks submitted voluntarily to the Mongol Empire and married into the imperial family. By 1218 the Mongols controlled all of Xinjiang and by 1221 all the territories of the former Khwarazmian Empire. In 1236, the Mongols defeated the eastern portions of Cumania and swept into Eastern Europe.

The Northern Yuan was a dynastic state ruled by the Mongol Borjigin clan based in the Mongolian Plateau. It existed as a rump state after the collapse of the Yuan dynasty in 1368 and lasted until its conquest by the Jurchen-led Later Jin dynasty in 1635. The Northern Yuan dynasty began with the retreat of the Yuan imperial court led by Toghon Temür (Emperor Huizong of Yuan) to the Mongolian steppe. This period featured factional struggles and the often only nominal role of the Great Khan.

Dayan Khan and Mandukhai Khatun reunited most Mongol tribes in the late 15th century. However, the former's distribution of his empire among his sons and relatives as fiefs caused the decentralization of the imperial rule. Despite this decentralization, a remarkable concord continued within the Dayan Khanid aristocracy, and intra-Chinggisid civil war remained unknown until the reign of Ligdan Khan (1604–1634), who saw much of his power weakened in his quarrels with the Mongol tribes and was defeated by the Later Jin dynasty. The last sixty years of this period featured the intensive penetration of Tibetan Buddhism into Mongol society.
