Since gaining foothold in Southeast Asian region by acquiring port of Malacca in 1511, Portuguese sent exploratory expeditions into Indonesian archipelago, and sought to dominate the sources of valuable spices and to extend their Roman Catholicmissionary efforts. Tomé Pires' Suma Oriental, written between 1512–1515, provides important information about 16th century Indonesia through Portuguese perspective. Initial Portuguese attempts to establish a coalition and peace treaty in 1522 with the West Javan Sunda Kingdom, failed due hostilities amongst indigenous kingdoms on Java. The Portuguese turned east to Maluku. Through both military conquest and alliance with local rulers, they established trading posts, forts, and missions in eastern Indonesia including the islands of Ternate, Ambon, and Solor. Following defeat in 1575 at Ternate at the hands of natives, Portuguese lost much of its trading posts and its former East Indies possessions to Dutch, and its presence in Indonesia was reduced to Solor, Flores and Timor in modern-day Nusa Tenggara. After the independence of Indonesia, the two countries officially opened diplomatic relations in 1950. Indonesia's first president Sukarno visited Portugal in 1960. The diplomatic relations were severed since 1964, and were restored in May 1975 for decolonization of Portuguese Timor neighboring Indonesian side of Timor Island However, on 7 December 1975 Portugal severed diplomatic ties following the Indonesian invasion of East Timor. Then 24 years later on 28 December 1999 Indonesia and Portugal restored their diplomatic ties, four months after East Timorese voted for independence from Indonesia. In May 2012 President Aníbal Cavaco Silva visited Indonesia, this was the first visit by a Portuguese president since the two countries opened diplomatic relations in 1950.
Culture
Portuguese was among the first European that made initial contact to the natives of Indonesian archipelago. The cultural impact can be seen through the adoptions of Portuguese loanwords in Indonesian, that mostly about things brought by Europeans, such as sabun, boneka, gereja, bola, bendera, sepatu, keju, and mentega. Portuguese influences can be found in various parts in Indonesia from Aceh in the West through Flores and Maluku in the East. In Jakarta, in the Tugu area, Portuguese descents are now living preserving the keroncong music which carries much influence from the Portuguese music. In Larantuka, Flores, every year ahead of the Easter Daythe city is full with pilgrims who wish to celebrate 'Semana Santa' or the Holy Week. Christians there conduct mass and rituals in Portuguese.
