Li Shimin did not marry a Turkic princess

Of course not. Li Shimin's most famous marriage was to marry his clan daughter, Princess Wencheng, to the king of Tubo, Songtsen Gampo.

Many of Li Shimin's 17 princesses went to other places with relatives, and the Tang Dynasty was so peaceful and stable because there were many relatives.

In order to consolidate the power of his emperor and consolidate the frontier, many of his princesses were sent to make peace.

Li Shimin did not have Turkic ancestry, his ancestry was a mixture of Han and Xianbei.

Li Yuan's father, Li Min, married the Xianbei wife Dugu (Li Yuan's biological mother). Dugu is the sister of Dugu, the empress of Emperor Wen of Sui Emperor Yang Jian, so Li Yuan and Emperor Yang Guang of Sui are cousins. It can be seen that Li Yuan has Xianbei blood.

Therefore, Li Shimin naturally also has Xianbei blood, not Turkic. At the same time, Li Shimin also married the eldest grandson of Xianbei's wife, and the eldest grandson, Dugu, Yuan, etc., which repeatedly appeared in Tang history, are all typical Xianbei surnames.

It's possible, but it's unlikely, he's a standard Xianbei nobleman.

In February of the fourteenth year of Zhenguan (640), Li Shimin sent General Zuo Xiaowei, Li Daoming, King of Huaiyang, and Murong Bao, General of Right Wuwei, to escort Princess Honghua into Tuyuhun to marry her king Nuo Haobo. Princess Honghua's entry into Tuguhun was the beginning of Tang marrying the princess to Waifu.

In the past 300 years, the Tang Dynasty has made peace with eight Hu tribes, including Turkic, Yeguhun, Tubo, Khitan, and Hui, a total of 28 times.
