What language did pallavas speak?
Likewise, people ask, what is the symbol of pallavas?
The Pallava royal insignia was the Simha (Lion) and Nandi (Bull) which was changeable. But Color of flags saffron or yellow. Each Pallava king had his own personal banner. Example, Narasimhavarman II used the lion as his emblem and Nandivarman II preferred the Nandi.
Thereof, are pallavas Brahmins?
So even if the Pallava kings were born in a Brahmin family, it's very unlikely they're called as Brahmins, as they became Kshatriyas. Further, there is evidence that Pallavas were group of tribes from Andhra Pradesh-Tamil Nadu border, but no record that they belong to Brahmin caste.
The Pallavas at the zenith of their power ruled present day Andhra Pradesh, the northern parts of Tamil Nadu, and parts of southern Karnataka. Their capital was at Kanchipuram (the region around Kanchi known as Tondaimandalam).
