South India is the area encompassing India's states of Andhra Pradesh, Karnataka, Kerala and Tamil Nadu as well as the union territories of Lakshadweep and Puducherry, occupying 19.31% of India's area. The region is also known as Dravida as is used in the National anthem.
A majority of Indians from the southern region speak one of the Dravidian languages: Kannada, Malayalam, Tamil, Telugu, and Tulu. During its history, a number of dynastic kingdoms ruled over parts of South India whose invasions across southern and southeastern Asia impacted the history and cultures of modern nation-states such as Sri Lanka, Singapore, the Philippines, Indonesia, Thailand and Malaysia. The region was colonised by Britain and gradually incorporated into the British Empire.
