What is the population of Luoyang City in Sui and Tang Dynasties?

With a total population of 2 million in Sui and Tang Dynasties, Luoyang was the first city with a population of more than 2 million in the history of the world and the most populous city in the world at that time.

In the early Tang Dynasty, the rulers organized many immigrants to Luoyang. Such as the generals in the late Sui Dynasty, Xiangzhou Renkang and so on.

Later, Wu Zetian proclaimed himself emperor, changed the Tang Dynasty to the Zhou Dynasty, and made Luoyang its capital, calling it the "Capital of the Gods". In order to enrich the population, Wu Zetian issued letters to encourage Yong and other States to immigrate to Luoyang. Farmers who move to Luoyang will enjoy the following major benefits: "The state will allocate land to those who have no land for three years, and at the same time allow them to go to the waterfront pier with their families and give them to ships as appropriate."

(See Wu Zetian's "Li Hong, Yi Ding Ji and other countries": "Those who are willing to learn from God should listen to it and pay it back in three years. People have no farm workers, so they can do whatever they want ... and allow their families to follow them so that water can be given to the boat. " )

Such preferential immigration measures have caused a sensation throughout the country, and people all over the country have responded.

So, in the autumn and July of the following year (69 1), hundreds of thousands of families moved to Luoyang in seven states, including Yongzhou and Tongzhou.

Chronicle of Old Tang Dynasty (then Tianzhi): "In autumn and July, hundreds of thousands of households in Neiyong and Tongqi moved to Luoyang."

By "hundreds of thousands" here, what are the specific hundreds of thousands? If it is calculated according to the minimum of 200,000, then there will be an average of 5 people in each household, which is 1 10,000 people. However, in ancient times, "200,000" was rarely recorded as 100,000, and most of the "100,000" in China ancient books were above 300,000. Therefore, according to the relatively open 300,000 households, with an average of 5 households, the population moving into Luoyang from other places is about 6.5438+0.5 million.

After the development and immigration in the early Tang Dynasty, in the Wu and Zhou Dynasties, the minimum population of Luoyang City will not be less than 400,000, and the public speculation can reach about 800,000. The population of Luoyang before immigration was about 400,000 ~ 800,000. After receiving100 ~10.5 million adherents, the population of Luoyang city reached1.4 ~ 2.3 million in 69 1 year. According to the latter, the population at this time has exceeded 2 million.

To sum up, Luoyang, the capital of Wu and Zhou Dynasties, is the first international metropolis with a population of over 2 million in the history of the world. The main reason is that on the basis of the original population of 800,000 in Luoyang City, Wu Zetian immigrated more than 6,543,800+people from various states. After more than ten years of five-state development, the population of Luoyang City, the capital of God, successfully exceeded two million.
