#World History# The author would like to reiterate a world historical knowledge: although the Vietnamese dynasty was a vassal state of the Chinese dynasty at the same time, the Vietnamese monarch only called the Chinese monarch king, and all the monarchs other than the Chinese monarch called the emperor, and the Chinese dynasty knew but acquiesced, so the Vietnamese monarch was like a false emperor, and the entire Southeast Asian history of the country only the Vietnamese monarch was the emperor, there are the following reasons:
1. The vassal state must use the era name of the suzerainty, and the posthumous title is "So-and-so King", but the monarchs of all the Vietnamese dynasties have their own era names, and the posthumous title is "Emperor so-and-so".
2. The Vietnamese dynasty has its own small clan relationship with the weak Lao dynasty and the Cambodian dynasty in the surrounding area, and the Vietnamese monarch is called the emperor as the monarch of the suzerainty.
3. Vietnam has always regarded itself as a small China, inherited the Chinese civilization, called the Chinese dynasty the Northern Dynasty, called its own dynasty the Southern Dynasty, and called the Southern Dynasty the Northern Dynasty, and the Vietnamese Dynasty thought that if it wanted to sit on an equal footing with the Chinese dynasty, it must be called the emperor.
4. Since Vietnam's independence from China in 968 AD, Chinese dynasties have all attacked the Vietnamese dynasty in the south, hoping to recover Vietnam, but almost repeatedly defeated, the loss of troops will be serious, the Vietnamese dynasty believes that the Chinese dynasty is simply unable to recover Vietnam, openly called the emperor, the Chinese dynasty although dissatisfied but has no heart at all, allowing the Vietnamese monarch to call the emperor, is a special case of the relationship between China and neighboring countries.
There may be other reasons, welcome to know the netizens to add.
