Explanations:The Saka Era, also known as the Saka calendar, is a historical calendar that was used in ancient India. It began in 78 CE and is associated with the reign of King Kanishka of the Kushan Empire. The Saka Era is significant in Indian history as it marks a period of cultural and political change in the region.
In the context of Kamrupa, a historical kingdom located in the Brahmaputra valley, the Saka Era is particularly important. Kamrupa was a powerful kingdom that existed in what is now the northeastern part of India, primarily in the present-day state of Assam. The rulers of Kamrupa played a significant role in the political and cultural landscape of the region during this period.
Debesvar, the correct answer, was the ruler of Kamrupa during the commencement of the Saka Era. Historical records and inscriptions indicate that Debesvar was a prominent figure in the early period of the Saka Era. His reign is marked by significant developments in the region, including the establishment of trade routes and the promotion of cultural activities.
It is important to note that the Saka Era is not only significant for its historical context but also for its impact on the cultural and social fabric of the region. The period saw the flourishing of art, literature, and architecture, which are still studied and appreciated today. Understanding the rulers and their contributions during this era is crucial for comprehending the historical and cultural development of the region.
While Banasur and Naraksur are mentioned as options, they are mythological figures and not historical rulers of Kamrupa. Bhagadutta, although a historical figure, is not associated with the early period of the Saka Era in Kamrupa. Therefore, Debesvar is the correct ruler of Kamrupa during the commencement of the Saka Era.
