After the death of King Sasanka sometime in the seventh century AD the political disintegration (The Matsya nyaya – Practice of the fishes) that followed landed Bengal in total anarchy and confusion and this continued for a century. The people who had suffered untold miseries for a long period suddenly developed a political wisdom. They perceived that the establishment of a single strong authority is the only remedy against this. So without any struggle the independent political chiefs recognised the suzerainty of a popular hero named Gopala. This marks the start of the first ruling dynasty of Bengal. – As sourced from History Of Ancient Bengal by R.C.Majumdar.
