The Portuguese introduced Catholicism in the 16th century, notably to the island of Flores and to what was to become East Timor. Protestantism was first introduced by the Dutch in the 16th century with Calvinist and Lutheran influences. For the Dutch, economic benefit rather than religious conversion were paramount, and missionary efforts avoided predominantly Muslim areas such as Java. The Dutch East India Company (VOC) regulated the missionary work so it could serve its own interests and focused it to the eastern, Animist part of the archipelago, including Maluku, North Sulawesi, Nusa Tenggara, Papua and Kalimantan. Christianity later spread from the coastal ports of Kalimantan, and missionaries arrived among the Torajans on Sulawesi. Parts of Sumatra were also targeted, most notably the Batak people who are predominantly Protestant today.
