Kochi formerly known as Cochin, is a city in the Indian state of Kerala. The city is one of the principal seaports of the country and is located in the district of Ernakulam, about 220 kilometres (137 mi) north of the state capital, Thiruvananthapuram. It has an estimated population of 600,000, with an extended metropolitan population of about 1.5 million, making it the largest urban agglomeration and the second largest city in Kerala after the capital.

The old Dutch cemetery in KochiKochi 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 traveller Niccolò Da Conti, who visited Kochi in 1440.

The Kingdom of Kochi came into existence in 1102, after the fall of the Kulasekhara empire.[9] 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.
