Geography

Kerala’s 38,863 km² landmass (1.18% of India) is wedged between the Arabian Sea to the west and the Western Ghats—identified as one of the world's twenty-five biodiversity hotspots to the east. Lying between north latitudes 8°18' and 12°48' and east longitudes 74°52' and 72°22', Kerala is well within the humid equatorial tropics. Kerala’s coast runs for some 580 km (360 miles), while the state itself varies between 35 and 120 km (22–75 miles) in width. Geographically, Kerala can be divided into three climatically distinct regions: the eastern highlands (rugged and cool mountainous terrain), the central midlands (rolling hills), and the western lowlands (coastal plains). Located at the extreme southern tip of the Indian subcontinent, Kerala lies near the centre of the Indian tectonic plate; as such, most of the state is subject to comparatively little seismic and volcanic activity. Pre-Cambrian and Pleistocene geological formations compose the bulk of Kerala’s terrain.


Eastern Kerala lies immediately west of the Western Ghats's rain shadow; it consists of high mountains, gorges and deep-cut valleys. 41 of Kerala’s west-flowing rivers, and 3 of its east-flowing ones originate in this region. Here, the Western Ghats form a wall of mountains interrupted only near Palakkad, where the Palakkad Gap breaks through to provide access to the rest of India. The Western Ghats rises on average to 1,500 m (4920 ft) above sea level, while the highest peaks may reach to 2,500 m (8200 ft). Just west of the mountains lie the midland plains composing central Kerala; rolling hills and valleys dominate. Generally ranging between elevations of 250–1,000 m (820–3300 ft), the eastern portions of the Nilgiri and Palni Hills include such formations as Agastyamalai and Anamalai.

Kerala’s western coastal belt is relatively flat, and is criss-crossed by a network of interconnected brackish canals, lakes, estuaries, and rivers known as the Kerala Backwaters. Lake Vembanad—Kerala’s largest body of water—dominates the Backwaters; it lies between Alappuzha and Kochi and is more than 200 km² in area. Around 8% of India's waterways (measured by length) are found in Kerala. The most important of Kerala’s forty four rivers include the Periyar (244 km), the Bharathapuzha (209 km), the Pamba (176 km), the Chaliyar (169 km), the Kadalundipuzha (130 km) and the Achankovil (128 km). The average length of the rivers of Kerala is 64 km. Most of the remainder are small and entirely fed by monsoon rains. These conditions result in the nearly year-round water logging of such western regions as Kuttanad, 500 km² of which lies below sea level. As Kerala's rivers are small and lack deltas, they are more prone to environmental factors. Kerala's rivers face many problems, including summer droughts, the building of large dams, sand mining, and pollution.

GROWTH OF KINGDOMS

The Chera kings' dependence on trade meant that merchants from West Asia and Southern Europe established coastal posts and settlements in Kerala. The Jewish, Christian, and Muslim immigrants established Nasrani Mappila and Muslim Mappila communities. 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, the first verifiable migration of Jewish-Nasrani families to Kerala is of the arrival of Knai Thoma in 345 AD . Muslim merchants (Malik ibn Dinar) settled in Kerala by the 8th century AD and introduced Islam. After Vasco Da Gama's arrival in 1498, the Portuguese gained control of the lucrative pepper trade by subduing Keralite communities and commerce.

Conflicts between Kozhikode (Calicut) and Kochi (Cochin) provided an opportunity for the Dutch to oust the Portuguese. In turn, the Dutch were ousted by Marthanda Varma who routed them at the Battle of Colachel in 1741. Hyder Ali, heading the Mysore, conquered northern Kerala, capturing Kozhikode in 1766. In the late 18th century, Tipu Sultan, Ali’s son and successor, launched campaigns against the expanding British East India Company; these resulted in two of the four Anglo-Mysore Wars. He ultimately ceded Malabar District and South Kanara to the Company in the 1790s. The Company then forged tributary alliances with Kochi (1791) and Travancore (1795). Malabar and South Kanara became part of the Madras Presidency.

Pazhassi Raja, the "Lion of Kerala", who waged a guerilla war against the British in the late 18th century.

Kerala saw comparatively little defiance of the British Raj. Nevertheless, several rebellions occurred, including the 1946 Punnapra-Vayalar revolt, and leaders like Velayudan Thampi Dalava, Kunjali Marakkar, and Pazhassi Raja earned their place in history and folklore. Many actions, spurred by such leaders as Vaikunda Swami, Sree Narayana Guru and Chattampi Swamikal, instead protested such conditions as untouchability; notable was the 1924 Vaikom Satyagraham. In 1936, Chitra Thirunal Bala Rama Varma of Travancore issued the Temple Entry Proclamation that opened Hindu temples to all castes; Cochin and Malabar soon did likewise. The 1921 Moplah Rebellion involved Mappila Muslims rioting against Hindus and the British Raj.


After India gained its independence in 1947, Travancore and Cochin were merged to form Travancore-Cochin on July 1, 1949. On January 1, 1950 (Republic Day), Travancore-Cochin was recognised as a state. The Madras Presidency was organised to form Madras State several years prior, in 1947. Finally, the Government of India's November 1, 1956 States Reorganisation Act inaugurated the state of Kerala, incorporating Malabar district, Travancore-Cochin (excluding four southern taluks, which were merged with Tamil Nadu), and the taluk of Kasargod, South Kanara. A new legislative assembly was also created, for which elections were first held in 1957. These resulted in a communist-led government through ballot - the world's first of its kind - headed by E.M.S. Namboodiripad. Subsequent social reforms favoured tenants and labourers. As a result, living standards, education, and life expectancy improved dramatically.
