Shailodbhava dynasty in the context of "Shashanka"

Kalinga is a historical region of India. It is generally defined as the eastern coastal region between the Ganges and the Godavari rivers, although its boundaries have fluctuated with the territory of its rulers. The core territory of Kalinga now encompasses all of Odisha and some part of northern Andhra Pradesh. At its widest extent, the Kalinga region also included parts of present-day Chhattisgarh, extending up to Amarkantak in the west. In the ancient period it extended until the bank of the Ganges river.

The Kalingas have been mentioned as a major tribe in the legendary text Mahabharata. In the 3rd century BCE, the region came under Mauryan control as a result of the Kalinga War. It was subsequently ruled by several regional dynasties whose rulers bore the title Kalingādhipati ("Lord of Kalinga"); these dynasties included Mahameghavahana, Vasishtha, Mathara, Pitrbhakta, Shailodbhava, Bhaumkara, Somavamshi, and Eastern Ganga. The medieval era rulers to rule over the Kalinga region were the Suryavamsa Gajapatis, Bhoi dynasty, Paralakhemundi Gangas and the zamindaris of Ganjam and Vizagapatam.

The Bhauma dynasty, also known as Kara dynasty, ruled in eastern India between 8th and 10th centuries. Their kingdom, called Toshala (IAST: Toṣala), included parts of present-day Odisha.

By the last quarter of the 8th century, the Bhauma-Karas had gained control of the former Shailodbhava territory. The early rulers of the dynasties followed Buddhism, and its later rulers followed Shaivism and Vaishnavism. The dynasty, whose rulers included seven women, was supplanted by the Bhanjas and the Somavamshis in the 10th century.
