Explanation:

Shashanka was the first independent king of a unified polity in the Bengal region, called the Gauda Kingdom and is a major figure in Bengali history. He reigned in 7th century AD, some historians place his rule between circa 600 C.E and 636/7 C.E.[1] Whereas other sources place his reign between 590 and 625 C.E.

He is the contemporary of Harsha and of Bhaskaravarman of KAMARUPA. His CAPITAL was at Karnasubarna, in present-day Murshidabad in West Bengal. The development of the Bengali calendar is often attributed to Shashanka because the starting date falls within his reign.[2][3][4]Not much is known about the early life of Shashanka. HISTORIAN D K Ganguly is reported to have concluded that he was a native of Magadha.[5]

The same source reports that the historian Padmanath Bhattacharya TOOK Shashanka to be a son of Mahasenagupta. R D Banerji concluded that he was descended from the Magadha Guptas. These views are opposed by other historians like B. S. Sinha and John Middleton, citing lack of evidence.

Nagendranath Basu has argued that Shashanka was the son / descendant of Raja Karnadeva, who founded the city of Karnasubarna.[6]

In some sources, Shashanka is described as a TRIBAL leader.[7]
