Explanation:

After the downfall of the Gupta Empire in the middle of the 6th century, North India was split into several independent kingdoms. The northern and western regions of India passed into the hands of a dozen or more feudatory states. Prabhakara Vardhana, the ruler of Sthanvisvara, who belonged to the Vardhana family, extended his control over neighbouring states. Prabhakar Vardhana was the first king of the Vardhana dynasty with his capital at Thaneswar. After Prabhakar Vardhana's death in 605, his eldest son, Rajya Vardhana, ascended the throne. Harsha Vardhana was Rajya Vardhana's younger brother. This period of kings from the same line has been referred to as the Vardhana dynasty in many publications.
