Kerala  is a state on the tropical Malabar Coast of southwestern India. To its east and northeast, Kerala borders Tamil Nadu and Karnataka; to its west and south lie the Indian Ocean islands of Lakshadweep and the Maldives, respectively. Kerala nearly envelops Mahé, a coastal exclave of Pondicherry. Kerala is one of four states that compose the linguistic-cultural region known as South India. The spoken language is Malayalam, but other languages are also spoken. Kerala ranks 12th by population nationwide and is the most densely populated state in India.

First settled in around 1000 BC by speakers of Proto-South Dravidian, Kerala was influenced by the Mauryan Empire. Later, the Cheran Kingdom and feudal Nair and Namboothiri Brahminical city-states became major powers in the region.  Early contact with overseas lands culminated in struggles between colonial and native powers. The States Reorganisation Act of 1 November 1956 elevated Kerala to statehood.

Social reforms enacted in the late 19th century by Cochin and Travancore were expanded upon by post-independence governments, making Kerala, India's longest-lived, healthiest, most gender-equitable, and most literate regions. Kerala has one of the most advanced educational systems in India. Though the state's basic human development indices are roughly equivalent to those in the developed world, the state is substantially more environmentally sustainable than Europe and North America. Nevertheless, Kerala's suicide, alcoholism, and unemployment rates rank among India's highest. A survey conducted in 2005 by Transparency International ranked Kerala as the least corrupt state in the country.

The etymology of Kerala is a matter of conjecture. In the prevailing theory, Kerala is an imperfect Malayalam portmanteau that fuses kera ("coconut palm tree") and alam ("land" or "location"). Another theory is that the name originated from the phrase chera alam ("Land of the Chera"). Natives of Kerala, known as Keralites or Malayalis, thus refer to their land as Keralam.

History of Kerala
According to legend, Kerala was an Asura Kingdom and was ruled by Asura kings. The last of the Asura kings, Maveli was killed by Vamana, one of the avatars of Mahavishnu. According to folk songs there was no caste system in Kerala during that period and the kingdom had very high ethical values. People of Kerala celebrate Onam in Maveli's memory. Maveli is referred to as Mahabali in Sanskrit texts.

According to another legend, Parasurama, who was the next avatar of Mahavishnu, threw his battle axe into the sea. As a result, the land of Kerala arose and was reclaimed from the waters. During Neolithic times, humans largely avoided Kerala's rainforests and wetlands. There is evidence of the emergence of prehistoric pottery and granite burial monuments in the 10th century BC that resemble their counterparts in Western Europe and the rest of Asia. These were produced by speakers of a proto-Tamil language. Thus, Kerala and Tamil Nadu once shared a common language, ethnicity and culture; this common area was known as Tamilakam. Kerala became a linguistically separate region by the early 14th century. The ancient Cherans, whose mother tongue and court language was Tamil, ruled Kerala from their capital at Vanchi and was the first major recorded kingdom. Allied with the Pallavas, they continually warred against the neighbouring Chola and Pandya kingdoms. A Keralite identity—distinct from the Tamils and associated with the second Chera empire—and the development of Malayalam evolved between the 8th and 14th centuries. In written records, Kerala was first mentioned in the Sanskrit epic Aitareya Aranyaka. Later, figures such as Katyayana, Patanjali, Pliny the Elder, and the unknown author of the Periplus of the Erythraean Sea displayed familiarity with Kerala.

Many, especially Jews and Christians, escaped persecution and established the Nasrani Mappila and Muslim Mappila communities. According to several scholars, the Jews first arrived in Kerala in 573 BC. The works of scholars and Eastern Christian writings state that Thomas the Apostle visited Muziris in Kerala in 52 AD to proselytize amongst Kerala's Jewish settlements. However, archeological evidences of existence are dating from 6th century. Eastern Christian writings points to migration of Christian families to Kerala in 3rd and 8th century respectively. Muslim merchants (Malik ibn Dinar) settled in Kerala by the 8th century AD. After Vasco Da Gama's arrival in 1498, the Portuguese gained control of the lucrative pepper trade by subduing Keralite communities and commerce.
