Why is Nanjing called the ancient capital of the Six Dynasties?

Since the 3rd century, Wu Dong, Jin Dong, Southern Song Dynasty, Nanqi, Nanliang and Nanchen have successively established their capitals here, so Nanjing is called the ancient capital of the Six Dynasties.

1 and 229 (the first year of Wu Huanglong), Sun was founded in the Eastern Jin Dynasty, with its capital in Jianye (now Nanjing).

2.3 17, Si Marui rebuilt the Jin Dynasty in Jiankang, which was called the Eastern Jin Dynasty in history and Jiankang (now Nanjing) as its capital.

In 3.420, Emperor Wu of the Eastern Jin Dynasty rose in troubled times, and finally the Jin Dynasty established the Song Dynasty, known as the Southern Song Dynasty in history, with its capital in Jiankang (now Nanjing).

4. In 479 AD, Xiao Daocheng forced Song to discuss the establishment of Qi State, which was called the Southern Dynasty in history and its capital was Jiankang (now Nanjing).

In 5.502, Xiao Yan, the secretariat of Yongzhou, replaced Nanqi to establish the Liang Dynasty, which was called Nanliang in history and Jiankang (now Nanjing) as the capital.

In 6.557, the Chen Dynasty was established, which was called the Southern Dynasty Chen in history, with Jiankang as its capital (now Nanjing).

Extended data:

The site of Jiankang City is preserved under Nanjing Library and Six Dynasties Museum. During the Six Dynasties, Jiankang City was the largest city in the world at that time, with a population of one million. It is the first city in the world with a population of over one million. China ancient culture was preserved in Nanjing by the Han nationality through the southern crossing of Yiguan. During the Six Dynasties, Nanjing and Rome were both called "the two centers of world classical civilization", and the culture of the Southern Dynasties, represented by Jiankang, had a far-reaching influence in human history.

Jiankang City in the Six Dynasties occupies an important position in the history of the development of the ancient capital of China, and it is the first example of the axisymmetric layout of the capital. Its plane layout and architectural form have a far-reaching impact on later generations, deeply affecting East Asian countries. Taicheng, the Forbidden City in the Six Dynasties, was imitated by the capitals of the Northern Wei Dynasty and East Asian countries, connecting the Qin and Han Dynasties with the Sui and Tang Dynasties, which profoundly influenced the shape of capital construction in later generations.
