The Esen Buqa–Ayurbarwada war was a war between the Chagatai Khanate under Esen Buqa I and the Yuan dynasty under Ayurbarwada Buyantu Khan (Emperor Renzong) and its ally the Ilkhanate under Öljaitü.
 The war ended with the victory for the Yuan and the Ilkhanate, but the peace only came after the death of Esen Buqa in 1318.
Barsbolad Jinong Khan (ᠪᠠᠷᠰ<br>ᠪᠣᠯᠤᠳ<br>ᠵᠢᠨᠦᠩ<br>ᠬᠠᠭᠠᠨ Mongolian: Барсболд жонон хаан , transliteration : Barsbold Jonon Khaan , aka : "Steel-Tiger" Jinong Khagan) or Barsbolad Khan (Mongolian: Барсболд хаан , translit.
 : Barsbold Khaan ), 1490–1531) was a Mongol Khagan of the Northern Yuan dynasty based in Mongolia from 1517 to 1519, and Jinong, from 1519 to 1531.
 Barsbolad Jinong was the third son of Dayan Khan, who appointed his grandson (the eldest son of Dayan Khan's second son), Bodi Alagh Khan as his successor.
 After the death of Dayan Khan, Barsbolad (Basbolud) Jinong proclaimed himself as the great khan, claiming that Bodi Alagh Khan was too young and too inexperienced to maintain the large Mongol empire, and he was able to rally support from some Mongol populace who feared that after a century of fighting, the unification and prosperity finally achieved by Manduhai khatun /Dayan Khan's adoptive mother and wife/ was to be lost and a more experience leader was needed.
 However, more than three years later, Bodi Alagh Khan allied with another uncle of his, the fourth son of Dayan Khan and challenged the Barsbolad Jinong, and both sides reached a compromise to avoid bloodshed among fellow Mongols: Barsbolad (Basbolud) Jinong would give up the crown and Bodi Alagh Khan would be the new Great Khan of Mongols, while his sons were also named as different khans.
 However, the loss of the crown of Great Khan of Mongol was too much for Barsbolad Jinong and he soon died afterward.
 He was the father of Altan Khan, one of the great leaders of the Northern Yuan.
 Barsbold was very well known for his bravery and exceptional military skills in his father's campaigns against Oirats and other Mongol fractions.
Gegeen Khan (Mongolian: "Шидэбал Гэгээн хаан", "Shidebal Gegegen qaγan"), born Shidibala, also known by the temple name Yingzong (Emperor Yingzong of Yuan, Chinese: 元英宗, February 22, 1302 – September 4, 1323), was the successor of Ayurbarwada to rule as Emperor of the Yuan dynasty.
 Apart from Emperor of China, he is regarded as the ninth Great Khan of the Mongol Empire or Mongols, although it was only nominal due to the division of the empire.
 His name means "enlightened/bright khan" in the Mongolian language.
The Mongol Empire (Mongolian: "Mongolyn Ezent Güren"    ; Mongolian Cyrillic: Монголын эзэнт гүрэн; ] ; also Орда ("Horde") in Russian chronicles) existed during the 13th and 14th centuries and was the largest contiguous land empire in history.
 Originating in the steppes of Central Asia, the Mongol Empire eventually stretched from Eastern Europe to the Sea of Japan, extending northwards into Siberia, eastwards and southwards into the Indian subcontinent, Indochina, and the Iranian plateau, and westwards as far as the Levant.
The Toluid Civil War was fought between Kublai Khan and his younger brother, Ariq Böke, from 1260 to 1264.
 Möngke Khan died in 1259 with no declared successor, precipitating infighting between members of the Tolui family line for the title of Great Khan that escalated to a civil war.
 The Toluid Civil War, and the wars that followed it (such as the Berke–Hulagu war and the Kaidu–Kublai war), weakened the authority of the Great Khan over the Mongol Empire and split the empire into autonomous khanates.
Ariq Böke (after 1219–1266), the components of his name also spelled Arigh, Arik and Bukha, Buka (Mongolian: Аригбөх ; Chinese: 阿里不哥), was the seventh and youngest son of Tolui, a grandson of Genghis Khan.
 After the death of his brother the Great Khan Möngke, Ariq Böke claimed the title of the Great Khan of the Mongol Empire and briefly took power while his brothers Kublai (more commonly known as Kublai Khan) and Hulagu (more commonly known as Hulagu Khan) were absent from the Mongolian homeland.
 When Kublai returned for an election in 1260, rival factions could not agree, and elected both claimants, Kublai and Ariq Böke, to the throne, resulting in the Toluid Civil War that fragmented the Mongol Empire.
 Ariq Böke was supported by the traditionalists of the Mongol Empire, while his brother Kublai was supported by the senior princes of North China and Manchuria.
Buyantu Khan (Mongolian: Буянт хаан), born Ayurbarwada, also known by the temple name Renzong (Emperor Renzong of Yuan (Chinese: 元仁宗, April 9, 1285 – March 1, 1320), was the fourth emperor of the Yuan dynasty.
 Apart from Emperor of China, he is regarded as the eighth Great Khan of the Mongol Empire or Mongols, although it was only nominal due to the division of the empire.
 His name means "blessed/good Khan" in the Mongolian language.
 His name "Ayurbarwada" was from a Sanskrit compound "Āyur-parvata", which means "the mountain of longevity", in contrast with Emperor Wuzong's name Qaišan ("mountains and seas" in Chinese).
Baiyunzong (白雲宗) was an offshoot of Buddhist Huayan school synthesized Buddhism, Confucianism and Taoism, viewed by Chinese Chán as heresy and was banned by Emperor Ningzong of Song, Ayurbarwada Buyantu Khan and Hongwu Emperor.
 They published the Buddhist canon Puningzang (普寧藏).
Empress Radnashiri (died 1322) was an Empress consort of the Yuan dynasty, married to Ayurbarwada Buyantu Khan (Emperor Renzong).
 She was from the Khunggirad tribe.
The Berke–Hulagu war was fought between two Mongol leaders, Berke Khan of the Golden Horde and Hulagu Khan of the Ilkhanate.
 It was fought mostly in the Caucasus mountains area in the 1260s after the destruction of Baghdad in 1258.
 The war overlaps with the Toluid Civil War in the Mongol Empire between two members of the Tolui family line, Kublai Khan and Ariq Böke, who both claimed the title of Great Khan (Khagan).
 Kublai allied with Hulagu, while Ariq Böke sided with Berke.
 Hulagu headed to Mongolia for the election of a new Khagan to succeed Möngke Khan, but the loss of the Battle of Ain Jalut to the Mamluks forced him to withdraw back to the Middle East.
 The Mamluk victory emboldened Berke to invade the Ilkhanate.
 The Berke–Hulagu war and the Toluid Civil War as well as the subsequent Kaidu–Kublai war marked a key moment in the fragmentation of the Mongol empire after the death of Möngke, the fourth Great Khan of the Mongol Empire.
