Kochi has a diverse, multicultural, and secular community consisting of Hindus, Christians, Muslims, Jains, Sikhs, Konkanis and Buddhists among other denominations. Today, the population of the city is a mix of people from all parts of Kerala and most of India. The city's pan-Indian nature is highlighted by the substantial presence of various ethnic communities from different parts of the country. Kochi earned a significant position on the world trading routes after the world famous port at Kodugallur (Cranganore) was destroyed by massive flooding of the river Periyar in 1340 AD. Records show that Kodugallur (Cranganore) was known to the Arabs and Chinese traders for centuries. After the Kodugallur port was destroyed, the forces of nature created a natural harbour at the nearby city - Kochi. Kochi started to grow and soon developed into a major trading point dealing in pepper, cardamom, cinnamon, cloves, etc., which were and still are famous for their quality. The Arabs, British, Chinese, Dutch, Italians and Portuguese helped Kochi emerge as a bustling centre of commercial activity, connecting the mainland to the rest of the world. Kochi owes a lot to great travellers, scholars and traders like Fa Hien, Vasco da Gama, Sir Robert Bristow, etc. to her growth and prosperity. The English called Kochi 'Mini England', the Dutch called it 'Homely Holland' and the Portuguese called it 'Little Lisbon' highlighting Kochi's prominence.
