The first raga to have been created is believed to be the Carnatic ayamalavagowla (equivalent to the Hindustani Bhairavi) that Purandara Dasa, the Bhakti poet and musician also known as Adi Guru, used as the teaching scale. Called the Adi Raga, it is said to have emanated from Lord Shiva. There are about 600 ragas shared between the Carnatic and Hindustani systems. Ragas may have the same bhava (emotion) but may have different names. Dikshitar, Tansen, Thyagaraja and other composers have all created ragas and new ragas are being created even today.
