South India, also known as Southern India or Peninsular India, is the southern part of the Deccan Peninsula in India encompassing the states of Andhra Pradesh, Karnataka, Kerala, Tamil Nadu and Telangana as well as the union territories of Lakshadweep and Puducherry, occupying 19.31% of India’s area (635,780 km2 or 245,480 sq mi) and 20% of India’s population. It is bound by the Bay of Bengal in the east, the Arabian Sea in the west and the Indian Ocean in the south. The geography of the region is diverse, with two mountain ranges, the Western and Eastern Ghats, bordering the plateau heartland. The Godavari, Krishna, Kaveri, Penna, Tungabhadra and Vaigai rivers are important non-perennial sources of water. Chennai, Bengaluru, Hyderabad, Coimbatore and Kochi are the largest urban areas in the region.

The majority of the people in South India speak at least one of the four major Dravidian languages: Telugu, Tamil, Kannada and Malayalam. During its history, a number of dynastic kingdoms ruled over parts of South India, and shaped the culture in those regions. Major dynasties that were established in South India include the Cheras, Cholas, Pandyas, Pallavas, Satavahanas, Chalukyas, Hoysalas, Rashtrakutas and Vijayanagara. European countries entered India through Kerala and the region was colonized by Britain, Portugal and France.

“South India” is also known as “Peninsular India” indicating its location in a peninsula surrounded by water on three sides. The term “Deccan”, referring to the area covered by the Deccan Plateau that covers most of peninsular India excluding the coastal areas, is an anglicised form of the Prakrit word dakkhiṇa derived from the Sanskrit word dakshiṇa meaning south. Carnatic, derived from “Karnāḍ” or “Karunāḍ” meaning high country, has also been associated with South India.

Popular destinations include Kerala, with its backwaters and beaches, Tamil Nadu’s temples and hill stations like Ooty and Kodaikanal, and Karnataka’s Hampi and Coorg.
