Kerala[a] is a state on the Malabar Coast of India. It was formed on 1 November 1956 under the States Reorganisation Act, which unified the country's Malayalam-speaking regions into a single state. Covering 38,863 km2 (15,005 sq mi), it is bordered by Karnataka to the north and northeast, Tamil Nadu to the east and south, and the Laccadive Sea to the west. With 33 million inhabitants according to the 2011 census, Kerala is the 13th-most populous state in India. It is divided into 14 districts, with Thiruvananthapuram as the capital. Malayalam is the most widely spoken language and, along with English, serves as an official language of the state.

Kerala has been a prominent exporter of spices since 3000 BCE. The Chera dynasty, the first major kingdom in the region, rose to prominence through maritime commerce but often faced invasions from the neighbouring Chola and Pandya dynasties. In the 15th century, the spice trade attracted Portuguese traders to Kerala, initiating European colonisation in India.

After Indian independence in 1947, Travancore and Cochin acceded to the newly formed republic and were merged in 1949 to form the state of Travancore-Cochin. In 1956, the modern state of Kerala was formed by merging the Malabar district, Travancore-Cochin (excluding four southern taluks), and the Kasargod taluk of South Kanara.

Kerala has the highest Human Development Index, at 0.784 in 2018; the highest literacy rate, 96.2% in 2018; the highest life expectancy, at 77.3 years; and the highest sex ratio, with 1,084 women per 1,000 men and the lowest positive population growth rate in India (3.44%). It is the least impoverished and the second-most urbanised state in the country. The state has witnessed significant emigration, particularly to the Arab states of the Persian Gulf during the Gulf Boom of the 1970s and early 1980s, and its economy relies heavily on remittances from a large Malayali expatriate population. Hinduism is practised by more than 54% of the population, followed by Islam and Christianity. The culture is a synthesis of Aryan and Dravidian traditions, shaped over millennia by influences from across India and abroad
