period before Marco Polo visited the city. Sulaiman al-Tajir, a Persian merchant who visited Kerala during the reign of Sthanu Ravi Varma (9th century CE), records that there was extensive trade between Kerala and China at that time, based at the port of Kollam. Kollam as "Colombo" in the Catalan Atlas (1375) In 13th century CE, Maravarman Kulasekara Pandyan I, a Pandya ruler fought a war in Venad and captured the city of Kollam. The city appears on the Catalan Atlas of 1375 CE as Columbo and Colobo. The map marks this city as a Christian city, ruled by a Christian ruler. The text above the picture of the king says: The city was much frequented by the Genoese merchants during the 13th-14th centuries CE, followed by the Dominican and Franciscan friars from Europe. The Genoese merchants called the city Colõbo/Colombo.

These words appear in the form of a toponym. The author then shows, through the Latin text of several other notarial deeds and the documents on church history, how Christopher Columbus - also carrying the same toponym.- was part of Mousso's family, and hence of the Indian lineage (although born in Genoa). Kozhikode Influences The port at Kozhikode held superior economic and political position in medieval Kerala coast, while Kannur, Kollam, and Kochi, were commercially important secondary ports, where the traders from various parts of the world would gather. Portuguese, Dutch and British Trade and Influences (16th to 18th centuries) The Portuguese arrived at Kappad Kozhikode in 1498 during the Age of Discovery, thus opening a direct sea route from Europe to India. They were the first Europeans to establish a
