Narasimhavarman I vs Sinjong of Goryeo

Narasimhavarman I established extensive sculpture workshops at Mamallapuram, producing masterpieces like the 'Descent of the Ganges' bas-relief. This patronage made Mamallapuram a center of art and architecture, influencing South Indian temple art.

Narasimhavarman I invaded the Chalukya capital of Vatapi (Badami) and destroyed it, avenging his father's defeat. This victory established Pallava dominance over the Chalukyas and earned him the title 'Mamalla' (great wrestler).

Narasimhavarman I commissioned the Pancha Rathas, five monolithic rock-cut temples at Mamallapuram, each carved from a single boulder. These structures represent different architectural styles and are a UNESCO World Heritage site, showcasing Pallava art.

Narasimhavarman I sent a naval expedition to Sri Lanka to support the deposed king Manavamma against the usurper. The Pallava fleet helped restore Manavamma to the throne, demonstrating Pallava naval power and influence in the Indian Ocean.

After deposing Myeongjong, military dictator Choe Chung-heon installed Sinjong as the new puppet king. Sinjong was a younger brother of the previous king and had no political experience, making him easily controllable.

Sinjong's reign was entirely ceremonial, with all state affairs managed by Choe Chung-heon's private military regime. The king had no authority over appointments, taxes, or military decisions.

Choe Chung-heon deposed Sinjong after only seven years, citing the king's inability to control factional strife. Sinjong was exiled and replaced by his son Huijong, further entrenching Choe control over the throne.
