Rashtrakuta in the context of "Pala Empire"

The history of southern India covers a span of over four thousand years, during which the region saw the rise and fall of a number of dynasties and empires.

The period of known history of southern India begins with the Iron Age (c. 1200 BCE – 200 BCE), Sangam period (c. 600 BCE – 300 CE) and Medieval southern India until the 15th century CE. Dynasties of Chera, Chola, Pandyan, Pallava, Travancore, Cochin, Zamorin, Kolathunadu, Chalukya, Satavahana, Rashtrakuta, Western Ganga, Kakatiya, Hoysala, Seuna, Bhonsle, Gaekwad, Scindia, Holkar, Patwardhan, Sangama, Saluva, Tuluva, Aravidu and Bahmani were at their peak during various periods of history.

Dharmapala was the second Pala emperor of Bengal (Vangala) in the Indian subcontinent. He was the son and successor of Gopala, the founder of the Pala dynasty. Dharmapala was mentioned as the King of Vangala (Vangala-bhūmipat) in the Nesari plates (dated 805 AD) of Rashtrakuta dynasty. He greatly expanded the boundaries of the empire and made the Palas a dominant power in the northern and eastern India.

Dharmapala directly ruled over the present-day Bengal and Bihar, and installed a nominee at Kannauj. The Pala chronicles also claim that several other rulers of North India acknowledged his suzerainty, but these claims seem to be exaggerated. Dharmapala was defeated twice by the Gurjara-Pratiharas, but each time the Rashtrakutas subsequently defeated the Pratiharas, leaving Palas as the dominant power in North India. Dharmapala was succeeded by his son Devapala who further expanded the empire.

The Pratihara dynasty, also called the Gurjara-Pratiharas, the Pratiharas of Kannauj or the Imperial Pratiharas, was a prominent medieval Indian dynasty which initially ruled the Gurjaradesa until its victory in the Tripartite Struggle in 816 which secured its right to the throne of Kannauj. Cadet branches of the dynasty ruled other minor states in the subcontinent.

The Pratiharas were instrumental in containing Arab armies moving east of the Indus River. Nagabhata I defeated the Arab army under Junaid and Tamin in the Caliphate campaigns in India. Under Nagabhata II, the Pratiharas became the most powerful dynasty in northern India. He was succeeded by his son Ramabhadra, who ruled briefly before being succeeded by his son, Mihira Bhoja. Under Bhoja and his successor Mahendrapala I, the Pratihara dynasty reached its peak of prosperity and power. By the time of Mahendrapala, the extent of its territory rivalled that of the Gupta Empire stretching from the border of Sindh in the west to Bengal in the east and from the Himalayas in the north to areas past the Narmada in the south. The expansion triggered a tripartite power struggle with the Rashtrakuta and Pala empires for control of the Indian subcontinent. During this period, Imperial Pratihara took the title of Maharajadhiraja of Āryāvarta (Great King of Kings of Aryan Lands).

The Kadamba dynasty were an ancient royal family from modern Karnataka, India, that ruled northern Karnataka and the Konkan from Banavasi in present-day Uttara Kannada district in India. The kingdom was founded by Mayurasharma in c. 345, and at later times showed the potential of developing into imperial proportions. An indication of their imperial ambitions is provided by the titles and epithets assumed by its rulers, and the marital relations they kept with other kingdoms and empires, such as the Vakatakas and Guptas of northern India. Mayurasharma defeated the armies of the Pallavas of Kanchi possibly with the help of some native tribes and claimed sovereignty. The Kadamba power reached its peak during the rule of Kakusthavarma.

The Kadambas were contemporaries of the Western Ganga dynasty and together they formed the earliest native kingdoms to rule the land with autonomy. From the mid-6th century the dynasty continued to rule as a vassal of larger Kannada empires, the Chalukya and the Rashtrakuta empires for over five hundred years during which time they branched into minor dynasties. Notable among these are the Kadambas of Goa, the Kadambas of Halasi and the Kadambas of Hangal. During the pre-Kadamba era the ruling families that controlled the Karnataka region, the Mauryas and later the Satavahanas, were not natives of the region and therefore the nucleus of power resided outside present-day Karnataka. The Kadambas were the first indigenous dynasty to use Kannada, the language of the soil, at an administrative level. In the History of Karnataka, this era serves as a broad-based historical starting point in the study of the development of the region as an enduring geo-political entity and Kannada as an important language.
