Kollam, formerly Desinganadu, is an old seaport and city on the Laccadive Sea coast in Kerala, India on Ashtamudi Lake. Kollam has had a strong commercial reputation since the days of the Phoenicians and Romans. Fed by the Chinese trade, it was mentioned by Ibn Battuta in the 14th century as one of the five Indian ports he had seen during the course of his twenty-four year travels. Desinganadu\'s rajas exchanged embassies with Chinese rulers while there was a flourishing Chinese settlement at Kollam. In the 9th Century, on his way to Canton, China, Persian merchant Sulaiman al-Tajir found Kollam to be the only port in India visited by huge Chinese junks. Marco Polo, the great Venetian traveller, who was in Chinese service under Kublai Khan in 1275, visited Kollam and other towns on the west coast, in his capacity as a Chinese mandarin.
V. Nagam Aiya in his Travancore State Manual records that in 822 AD two East Syrian bishops Mar Sabor and Mar Proth, settled in Quilon with their followers. Two years later the Malabar Era began (824 AD) and Quilon became the premier city of the Malabar region ahead of Travancore and Cochin.Kollam Port was founded by Mar Sabor at Thangasseri in 825 as an alternative to reopening the inland sea port of Kore-ke-ni Kollam near Backare (Thevalakara), which was also known as Nelcynda and Tyndis to the Romans and Greeks and as Thondi to the Tamils.
