In the fifteenth century, before the arrival of the Portuguese, Tetum had spread through central and eastern Timor as a contact language under the aegis of the Belunese-speaking Kingdom of Wehali, at that time the most powerful kingdom in the island. The Portuguese (present in Timor from c. 1556) made most of their settlements in the west, where Dawan was spoken, and it was not until 1769, when the capital was moved from Lifau (Oecussi) to Dili that they began to promote Tetum as an inter-regional language in their colony. Timor was one of the few Portuguese colonies where a local language, and not a form of Portuguese, became the lingua franca: this is because Portuguese rule was indirect rather than direct, the Europeans governing through local kings who embraced Catholicism and became vassals of the King of Portugal.
