Question

In Europe, this led to the rise of local, self-reliant, tribal governments and the early medieval
system. When the Han Dynasty fell in China, the empire was split into smaller and even smaller
independent later

Answer 1

It looks like you were finishing a comparison. Here are a corrected sentence and a concise explanatory paragraph you can use.

Corrected sentence (single line)
- When the Han Dynasty fell in 220 CE, the empire broke into progressively smaller independent states (the Three Kingdoms, then the Sixteen Kingdoms and the Northern and Southern Dynasties), before China was reunified under the Sui and Tang.

Short explanatory paragraph (comparison with Europe)
- Both the fall of Rome and the fall of the Han produced political fragmentation and local powerholders, but the outcomes differed. In Europe the Western Roman collapse (5th century) led to long-lasting localized, self-reliant polities and the early medieval/feudal order. In China, fragmentation was usually shorter and punctuated by repeated reunifications: despite divisions, many imperial institutions, Confucian culture, administrative practices and (later) the civil service tradition persisted or were re-adopted even by non-Han regimes, allowing relatively quicker restoration of central rule under the Sui (581–618) and Tang (618–907).

If you want, I can tailor the wording for an essay sentence, a textbook-style summary, or a bullet-point timeline with dates and key states.
