Tamil. According to C. V. Vaidya, the Pallavas were Maharashtrian Aryans who spoke Maharashtri Prakrit for centuries and hence retained it even in the midst of surrounding Dravidian languages. They may even be said to have been 'Marathas' for their name was said to be still preserved in the Maratha family name of 'Pālave' (which is just Prakrit form of Pallava). And a further corroboration is that the gotra of the Pālave Maratha family is Bharadwaja, same as the one which Pallavas have attributed to themselves in their records. Overlaid on these theories is another hypothesis of Sathianathaier which claims that "Pallava" is a derivative of Pahlava (the Sanskrit term for Parthians). According to him, partial support for the theory can be derived from a crown shaped like an elephant's scalp depicted on some sculptures, which seems to resemble the crown of Demetrius I. Rivalries With Cholas The Pallavas captured Kanchi from the Cholas as recorded in the Velurpalaiyam Plates, around the reign of the fifth king of the Pallava line Kumaravishnu I. Thereafter Kanchi figures in inscriptions as the capital of the Pallavas. The Cholas drove the Pallavas away from Kanchi in the mid-4th century, in the reign of Vishnugopa, the tenth king of the Pallava line. The Pallavas re-captured Kanchi from the Kalabhras in the mid-6th century, possibly in the reign of Simhavishnu, the fourteenth king of the Pallava line, whom the Kasakudi plates state as "the lion of the earth". Thereafter the Pallavas held on to Kanchi until the 9th century, until the reign of their last king, Vijaya-Nripatungavarman. With Kadambas The Pallavas were in conflict with major kingdoms at various periods of time. A contest for political supremacy existed between the early Pallavas and the Kadambas. Numerous Kadamba inscriptions provide details of Pallava-Kadamba hostilities. With Kalabhras During the reign of Vishnugopavarman II (approx. 500–525), political convulsion engulfed the Pallavas due to the Kalabhra invasion of the Tamil country. Towards the close of the 6th century, the Pallava Simhavishnu stuck a blow against the Kalabhras. The Pandyas followed suit. Thereafter the Tamil country was divided between the Pallavas in the north with Kanchipuram as their capital, and Pandyas in the south with Madurai as their capital. Birudas The royal custom of using a series of descriptive honorific titles, Birudas, was particularly prevalent among the Pallavas. The birudas of Mahendravarman I are in Sanskrit, Tamil and Telugu.
