The Mongol Empire proved to be much too large for Genghis Khan's remaining sons to administer. This is why the nation itself split off into separate controlled areas by which each of his sons had control off. Prior to this, sibling feuds had become a common thing between them anyway, so it's not hard to believe that anarchy took place in between the time of the Khans death, and before they split during very late years this empire existed. These regions held out on their own for a limited amount of time before falling in a matter of years that were rather petty compared to that of what Genghis Khan formed. The Yuan dynasty was one of the new growing powers within China, really a signal of death to where the Mongol Empire would end, seeing as the Chinese already began seizing smaller parts of southern Mongolia, cutting them off more.

You're operating on unfounded assumption which doesn't have merit in a discussion like this.

The succession between Ogedei from Genghis Khan was painless as opposed to the fifteen years of succession crisis that followed Timur in his later Empire. His brothers Jochi and Chagatai both supported the ascension of Ogedei and their father's wishes. Once more Jochi died of natural causes so he wouldn't have ever been an issue. Chagatai held his own khanate below his brother.

You don't really get an attempt at seizing the Khanate against the proclamation by the Mongol elective council - the kurultai - until Mongke when Genghis Khan's last brother [url=https://en.wikipedia.org/wiki/Tem%C3%BCge]Temuge[/url] tried to take it. But the effort was so lapse and minor that it's hardly a military crisis on how little conflict there is on it; unlike the attempted succession of Timur if I might re-iterate which resulted in 15 years of violence and the loss of Samarkand and other territories.

The first actual "civil war" is with Kublai Khan. But by this point the Empire had lapsed so much it didn't matter anymore. By this point Kublai was already the Emperor of China. And by the time of Kublai Khan any and all direct relatives of Genghis Khan were dead.

You can't presume, "There could have been violence". Because you're just showing your cards you aren't even trying.
