Parameswaravarman I was a Pallava emperor who reigned in southern India in the latter half of the 7th century, 670 - 695 CE. He ascended to the throne after the death of his father Mahendravarman II in 670 CE. His grandfather Narasimhavarman I had already made the Pallava empire the most powerful force in the subcontinent and destroyed the Chalukya capital at Vatapi. Parameswaravarman was an efficient and capable ruler, known for his military exploits, his love for poetry and his devotion to the God Siva, to whom he erected many temples. Parameswaravarman's reign was marked by revived conflicts with the Chalukyas, led by Vikramaditya I who had fought against his grandfather and was now allied with many rulers. In 674 CE, the two armies met at Peruvalanallur near Tiruchirappalli and Parameswaravarman was victorious stupendously despite facing a huge coalition. He was succeeded by his son Narasimhavarman II also called Rajasimha in 695 CE.
