The Rajas of Kochi were the rulers of the princely state of Kochi, located in present-day Kerala, India. They played a significant role in the region's history from the 12th century until the integration of Kochi into the Indian Union in 1949. The dynasty is known for its contributions to trade, culture, and the arts, particularly in the development of Kathakali and Mohiniyattam dance forms. The most notable Raja was Raja Keshava Dasan, who ruled in the 18th century and is credited with modernizing the state. The Rajas maintained diplomatic relations with European powers, including the Portuguese and Dutch, which influenced Kochi's economic and cultural landscape.
