Kochi was the centre of Indian spice trade for many centuries, and was known to the Yavanas (Greeks) as well as Romans, Jews, Arabs, and Chinese since ancient times. Kochi rose to significance as a trading centre after the port at Kodungallur (Cranganore) was destroyed by massive flooding of the river Periyar in 1341. The earliest documented references to Kochi occur in books written by Chinese voyager Ma Huan during his visit to Kochi in the 15th century as part of Admiral Zheng He’s treasure fleet. There are also references to Kochi in accounts written by Italian traveler Niccolò Da Conti, who visited Kochi in 1440.

The Kingdom of Kochi came into existence in 1102, after the fall of the Kulasekhara Empire. The King of Kochi had authority over the region encompassing the present city of Kochi and adjoining areas. The reign was hereditary, and the family that ruled over Kochi was known as the Cochin Royal Family (Perumpadappu Swaroopam in the local vernacular). The mainland Kochi remained the capital of the princely state since the 18th century.

However, during much of this time, the kingdom was under foreign rule, and the King often only had titular privileges. The formation of Cochin harbor has a violent story of which nature herself was the main character. The harbor was formed in A.D. 1341, when a great flood in the Periyar River led to an outlet in the sea. The floods had meanwhile silted up the mouth of the Muziris harbor and this rich ancient port was banished to the footnotes of history. Meanwhile, the merchants of Muziris shifted to Cochin.

For centuries, Cochin was the battleground of European powers for the mastery of the lucrative trade of the Indian west coast. The fortunes of political powers in Cochin were dictated by pepper. The Portuguese were the first to come in. Two years later, the adventurous mariner, the legendary Vasco da Gama himself landed in Cochin. The Portuguese erected a fort for the protection of their factory. Fort Manuel, or Manuel Kotta, named after the King of Portugal, was the first fortress constructed by the Europeans in India.

To the Portuguese must go the credit for the extensive scientific cultivation of coconut, ginger, and pepper, backbone of Kerala’s economy today? Tobacco, cashew nut, and fruit cultivation were also introduced. The pineapple, for instance, is still called prithichakka in Malayalam, meaning Portuguese jackfruit. They were also responsible for today’s burgeoning trade in coir.

The Dutch, full of energy and zeal, were next to entering the scene and succeeded in throwing out the Portuguese very soon. Helped by a laissez-faire policy and a self-stipulated dictum of “at least a 100% profit,” Cochin saw a great resurgence of trade. Cochin was declared a major port in 1936. With its opening, there was a complete reorientation of shipping and commercial activities on the Malabar Coast. With its year-round shipping facilities, it is the busiest port south of Bombay, lying as it does on the direct route to Australia and the Far East from Europe and serving the vast southern hinterland of industrial areas and plantations. It is a passenger port for the United Kingdom and America in South India. Moreover, it is one of the few ports of the world with all the three main forms of transport—land, sea, and air, centered in the same place.

In 1947, India gained independence from the British colonial rule. Cochin was the first princely state to join the Indian Union willingly. In 1949, Travancore-Cochin state came into being with the merger of Cochin and Travancore. The King of Travancore was the Rajpramukh of the Travancore-Cochin Union from 1949 to 1956. Travancore-Cochin was in turn merged with the Malabar district of the Madras State. Finally, the Government of India’s States Reorganization Act (1956) inaugurated a new state — Kerala — incorporating Travancore-Cochin (excluding the four southern Taluks which were merged with Tamil Nadu), Malabar District, and the taluk of Kasargod, South Kanara.

On 9 July 1960, the Mattancherry council passed a resolution—which was forwarded to the government—requesting the formation of a municipal corporation by combining the existing municipalities of Fort Kochi, Mattancherry, and Ernakulum. The government appointed a commission to study the feasibility of the suggested merger. Based on its report, the Kerala Legislative Assembly approved the corporation’s formation. On 1 November 1967, exactly eleven years since the establishment of the state of Kerala, the corporation of Cochin came into existence. The merger leading to the establishment of the corporation, was between the municipalities of Ernakulum, Mattancherry and Fort Kochi, along with that of the Willingdon Island, four panchayats (Palluruthy, Vennala, Vyttila and Edappally), and the small islands of Gundu and Ramanthuruth.
