List of emperors of the Han dynasty
The Han dynasty was founded by the peasant rebel leader (Liu Bang), known posthumously as Emperor Gao ("r". 202 –195 BC) or Gaodi. The longest reigning emperor of the dynasty was Emperor Wu ("r". 141–87 BC), or Wudi, who reigned for 54 years. The dynasty was briefly interrupted by the Xin dynasty of the former regent Wang Mang, but he was overthrown in 23 AD and the Han dynasty was reestablished by Liu Xiu, known posthumously as Emperor Guangwu (r. 25–57 AD), or Guangwu Di. The last Han emperor, Emperor Xian ("r". 189–220 AD), was a puppet monarch of Chancellor Cao Cao (155–220 AD), who dominated the court and was made King of Wei. In 220 AD, Cao's son Pi usurped the throne as Emperor Wen of Wei ("r". 220–226 AD) and ended the Han dynasty.

Regarding the words Late Han, Siku Quanshu Zongmu Tiyao (四庫全書總目提要)
argued that "presumably, Wang Can died when the Han dynasty still existed.
Though there were so many symptoms that the Han dynasty was near its death,
Emperor Xian still was on the throne. Wang Can surely could not use the words 
of Late Han as the title of his book, therefore Late Han 
is thought to be introduced by the future generations.
However as Wang Can described Cao Cao as holy ruler (聖君) in his book 
"A Poem of Military Service" (從軍詩), we cannot not say with full certainty that Wang Can
did not put Late Han in the title of his book".
