Kublai Khan was not recognized by his family. In fact, it started with Kublai Khan's eldest brother Mongo. At that time, Mongo inherited the position of Khan, and many people did not support it, but at that time, Mongo was strong and acquiesced. Later, after Mungo's death, it was normal for Kublai Khan and Mungo's younger brother Ali to inherit. After all, the local de facto ruler of the Mongolian Khanate of the Ali brothers at that time only needed one meeting to be recognized. But Kublai Khan took the lead and became a great Khan with the support of his subordinates. Such a hasty meeting did not conform to Mongolian tradition, so the family kings at that time did not recognize Kublai Khan.

Later, there was a big war between Alibaba Brother and Kublai Khan. After many battles, Ali Buge was defeated and surrendered to Kublai Khan. In order to win people's hearts, Kublai Khan only put Alibaba under house arrest, but destroyed many henchmen. In this way, many supporters of Alibaba brothers in other places strongly disagreed with Kublai Khan, and many factions in the family did not support him, so Kublai Khan was still not recognized.

In order to gain the orthodox position of Khan, Kublai Khan wanted to hold a Kublai Khan meeting and invite important people scattered all over the country. But at that time, many clansmen in power did not gather enough people to attend the meeting because they did not like or disapprove of Kublai Khan. With the passage of time, people with enough status gradually died, and this meeting was never held again, which meant that Kublai Khan's position in Mongolia was not recognized by his family.

For Kublai Khan, it is indeed a pity that the Khanate was not recognized by the family. After all, the Mongolian empire at that time had a large territory and had been divided into several khanates scattered in Eurasia. Kublai Khan also unified the whole Central Plains, breached the Song State, and thus established the Dayuan regime.
