Andhra Pradesh :
is a state in south-eastern India and is part of the linguistic-cultural region of South India. It lies between 12°41' and 22°N latitude and 77° and 84°40'E longitude, and is bounded by Maharashtra, Chhattisgarh and Orissa in the north, the Bay of Bengal in the east, Tamil Nadu to the south and Karnataka to the west. Andhra Pradesh is the fifth largest state in India and it forms the major link between the north and the south of India. It is the biggest and most populous state in the south of India. It is considered the rice bowl of India. The state is crisscrossed by two major rivers, the Godavari and Krishna. ("Pradesh" means "region" or "state".)
Sanskrit writings from the 7th century BC describe the Andhra people as Aryans from the north who migrated south of the Vindhya Range and mixed with Dravidians. They are mentioned again at the time of the death of the great Mauryan King Ashoka, in 232 BC. This date has been held to be the beginning of the Andhra historical record. The Andhras are first mentioned in the Aitareya Brahamana. They first rose to prominence under the Satavahana Dynasty. Various dynasties have ruled the area, including the Andhra (or Satavahana), Ikshvakas, Badami Chalukyas, Rashtrakutas, Chalukyas of Kalyana, Eastern Chalukyas, Kakatiyas, Vijayanagar, the Qutb Shahis, and the Nizams (princes) of Hyderabad.
Andhra Pradesh can be broadly divided into three regions, namely Coastal Andhra (Konaseema), Telangana and Rayalaseema.Coastal Andhra occupies the coastal plain between Eastern Ghats ranges, which run the length of the state, and the Bay of Bengal.Telangana lies west of the Ghats on the Deccan plateau. The Godavari and Krishna rivers rise in the Western Ghats of Karnataka and Maharashtra and flow east across Telangana to empty into the Bay of Bengal in a combined river delta .
Rayalaseema lies in the southeast of the state on the Deccan plateau, in the basin of the Penner River. It is separated from Telangana by the low Erramala hills, and from Coastal Andhra by the Eastern Ghats.
The Krishna and Godavari rivers together irrigate thousands of square kilometres of land, and create the largest perennial cultivable area in the country. Andhra Pradesh leads in the production of rice (paddy) and is called India's Rice Bowl.
