Genghis motherfucking Khan

Despite being very similar, he is not the same person as Jaghatai Khan.

Chinggis Haan (more commonly known in the English-speaking world as Genghis Khan and Genghis 'Motherfucking' Khan to the assholes of /tg/) was a 12th century Mongolian warlord and Khagan (Emperor) who, in 1206 CE, succeeded in uniting the Mongol tribes of Northeastern Asia into what would become known as the Mongol Empire. Contrary to popular belief, he was not the first individual chieftain to attempt in creating a unified Mongol confederation; the first having been his great-great grandfather Habul Haan who established the Khamaag Mongol confederation. Chinggis was infinitely more successful though, and managed to unite nearly all the disparate Mongol factions into his empire; which is why he is considered by modern day Mongolians as the founding father of the Mongol state.

Born Temujiin, meaning 'man of iron' and thought to be derived from a Northeastern Turkic word, he was the son of Yesukhei (later to be known as Yesukhei Bahadur or 'Yesukhei the Warrior' after being dubbed posthumously so by Chinggis), who was chieftain of the Borjigid tribe (Grey-Blue wolf tribe) and descended from the legendary warrior-king Bodonchar Munkhaag (lit. Bodonchar the Bastard, dubbed so for his illegitimate birth). In turn, Temujiin was also descended from Borte Chino, the great wolf and mythical forebear of the Borjigid tribe.

Chinggis is notable primarily for being a warlord and having waged the Mongol Invasions of Asia and Europe, which collectively resulted in the massacre of 40 million people; which amounts to 10% of the world's population at that time. He's also notable for having 0.4% percent of the world's population springing forth from his mighty loins, which makes him akin to a real world equivalent to Walder Frey from A Song of Ice and Fire. Or at least he would if Frey was an apocalyptic level badass and not an underachieving old lecherous fuckwit. For obvious reasons, most of these people tend to be from Central Asia (Mongolia, Kazakhstan, Kyrgyzstan, Uzbekistan, Turkmenistan, East Turkestan, Tajikistan, Afghanistan), some parts of South Asia (primarily northern India and Pakistan) and Siberia and Turkic Russia (Republic of Tatarstan, Republic of Baskhortostan) and most of them are Muslim. Descent from Chinggis Haan is so wide-spread that it even has a name; Altan Urag, which translates roughly to 'Golden Lineage' and is also the name of that Mongolian folk-rock band. In Kazakh, this is called 'Töre'. Historically, a person descended from Chinggis Haan would be called 'Chinggisid', in the tradition of Central Asian tribes deriving their names from their founders and adding '-id'; meaning 'descended from', compare with the Scandinavian '-linga' suffix.

Despite his highly noble birth, Chinggis was born at a time when mediaeval Mongol tribes were constantly at each other's throats in a manner not dissimilar to how the Warriors of Chaos in Warhammer Fantasy are every fucking second of every fucking day until the Everchosen decides to smack heads together (incidentally, the Kurgan, one of the three groups comprising the Warriors of Chaos, is based off the Mongols). Except Mongolia is less cold and marginally less dangerous than Norsca. Chinggis would grow up to be the Everchosen of this scenario, in terms how apocalyptic his eventual rise to power would be to the people south of him, much like how the Everchosen is. Hell, he even claimed divine favour from Tengger Etseg (lit. Sky-Father) - the Mongol god of thunder and head of the Mongolian pantheon. For much of his childhood however, his lot was to be married off by his father Yesukhei in order to secure an alliance with the Khongiraat tribe; where he would later meet his wife Borte. Unfortunately for the future Chinggis Haan, daddy ran afoul of the neighbouring Siberian Tatar tribes to the North and ended up with his skull being used for some Tatar Haan's koumyss. After that, Temujiin's family was swiftly usurped from the position of chieftain by one of his father's anda (bondsman, essentially) and so was he cast out with his brothers Begter, Hasar, Hachiun and Temuge and his mother.

Despite not being 12, Temujiin managed to look after his family, making ends meet and carving out an existence in one of the most hostile environments on earth. He even killed his elder brother Begter over a dispute over hunting spoils, to give you an idea of how harsh living conditions were at the time. Interestingly, around this time he was captured and made a slave by the Tayichi'ud tribe of Mongolia, but managed to escape through his balls-to-the-wall insanity and the aid of a sympathetic guard. He apparently must have pulled some Conan the Barbarian level shit there, since he earned something of a mythical reputation shortly thereafter. Later on, he reunited with Borte and married her, only to have her stolen by the Merkit tribe (bride-kidnapping was nothing unusual in Mongolia at the time and is still used symbolically in some Central Asian countries as a sort of courtship ritual). Despite the fact that most Mongols at the time would simply shrug and steal another wife from somewhere else, Chinggis was not one to accept defeat willingly and swiftly gathered warriors to raid the Merkit tribe in order to recover Borte. A particularly bloody affair it would seem, as a few folk-tales supposedly tell of how Chinggis devoured the perpetrators of the kidnapping in a shamanic ritual.
