Yikang

Yigang, of the Aisin Gioro clan, was the second son of the Daoguang Emperor of the Qing Dynasty. He was born on October 23, in the sixth year of Daoguang’s reign (1826). His mother was Noble Consort Borjigit. His half-brother was Yishan. According to historical records, Yigang died on the eighth day of the second month of the seventh year of Daoguang’s reign (1827), at the age of five months. Official documents and court archives record his birth and early death, with the cause of death listed as smallpox. He contracted the disease and died after the pustules appeared; four days before his death, preparations were made in the palace to send the Doting Goddess (痘神娘娘) on February 13. This account indicates that he became ill and passed away at a very young age, and he did not inherit a higher title.

Regarding his status within the imperial family, there are no factual records in historical materials about any official rank or formal title he held as an adult. His half-brother Yishan was posthumously granted titles later on, becoming Shunjun Prince, with the posthumous name He. This is documented in the genealogical records of the imperial house in the period after Daoguang, reflecting the common practice of bestowing titles and posthumous names to brothers of the emperor in subsequent generations. The main genealogical information related to Yigang focuses on his father, the Daoguang Emperor, his mother’s identity, and his siblings; there are no notable records about his adult deeds or subsequent honors in existing historical sources.

In scholarly references, information about Yigang and his familial relations mainly comes from Qing Dynasty archives and genealogical writings of the imperial family. Related extended reading includes volumes such as the "Draft History of Qing" (Qingshi Gao), particularly volume 221, authored by Zhao Erxun, as well as genealogical records found in works like "The Four Genealogies of the Qing Imperial House." These sources typically organize information based on court archives, titles, and posthumous names, presented in chronological order.

This biography is based solely on publicly available historical materials and does not include unverified rumors or speculative content. If future research includes interpretive analyses of original archives, it may provide more detailed evidence regarding his birthplace, childhood experiences, and family genealogy.
