Rishikas
The Rishikas (also Rshika and Ṛṣika) was an ancient Kingdom of Central Asia and South Asia, who are mentioned in Hindu and Sanskrit literary texts, including the Mahabharata, the Ramayana, the Brhat-Samhita, the Markendeya Purana and Patanjali's Mahabhashya. Some historians believe the Rishikas were a part of, or synonymous with, the Kambojas.
