Cuddalore /kʌdəˈlɔər/, is a city which is the headquarters of the Cuddalore District in the south Indian state of Tamil Nadu. Scholars believe the name Cuddalore is derived from Koodalur, meaning confluence in Tamil. While the early history of Cuddalore remains unclear, the town first rose to prominence during the reign of Pallavas and Medieval Cholas. After the fall of Cholas, the town was ruled by various dynasties like Pandyas, Vijayanagar Empire, Madurai Nayaks, Thanjavur Nayaks, Thajavur Marathas, Tipu Sultan, French and the British Empire. Cuddalore was the scene of Seven Years' War and the Battle of Cuddalore in 1758 between the French and British. It has been a part of independent India since 1947. During the 2004 Indian Ocean earthquake, Cuddalore was one of the affected towns, with 572 casualties.
