The Portuguese had captured most of the Western maritime provinces as well as areas near Gokanna, i.e., Trincomalee (named Triquillemele in De Queyroz) and Madakalapuwa, i.e., Batticaloa (Battacilow in William Broedelet's 1692 map).The Portuguese Captain Major Philippe de Oliveira had captured the Northern peninsula (Jaffnapatuna) and its ruler Sankilli-II ( Cankili Kumaran) in 1619 CE.
The British signed a treaty with the Kandyan Adigars (minsters) handing over Sinhalé to the British in return for their guaranteeing various rights including the primacy of Buddhism.
It soon became evident that the "Kandyan convention" was a sham which was not being respected by the British.
Subsequent names, e.g., 'Ceilao', "Ceilan", `Ceylam', Ceylan', Zeilon, and Ceylon are adapted from "Serendib". The Frenchman Sier Sanson's 1652 map uses 'Ceylan'.
The Dutch map of 1681 uses the name Ceylon and Conde Uda to refer to the kingdom of Kandy (Conde).
The Jaffna Peninsula was finally recaptured in 1921 from Sinhalese rule by the Portuguese General Constantino de Sa de Noronha.
Although Denmark had signed a treaty with the King of Kandy for building a fort in Batticaloa, the Dutch overcame them.In this the Portuguese were supported by low-caste tamils who had been converted to Christianity already during the co-habitation of Sankili-I with the Portuguese.However, Mudliyar Attapattu who had been dispatched by the King of Kandy (Senerat) with an army of 10,000 defeated the the Portuguese soon after, as documented then by Joao Ribeiro and more recently by Tikiri Abeysinghe, (Jaffna under the Portuguese ISBN 955-1131-70-1).However, the name Salaka was also used in Greek, at the time.`Taprobane' is believed to be derived from `Tambapanni', a name allegedly given to the island by Founder-Prince, Vijaya, because of the golden brown sands of the coast near Mannar (Manthota) where he landed.Use of the material for scholarly and academic purposes with due acknowledgment is welcome. The name Lanka, used in the Epic chronicles, was adopted in to Prakrit with the addition of a leading vowel which could be "a, e, (h)e, or i".
