Despite the Dutch presence in Indonesia for almost 350 years, as the Asian bulk of the Dutch East Indies, the Dutch language has no official status there and the small minority that can speak the language fluently are either educated members of the oldest generation, or employed in the legal profession, as some legal codes are still only available in Dutch. Dutch is taught in various educational centres in Indonesia, the most important of which is the Erasmus Language Centre (ETC) in Jakarta. Each year, some 1,500 to 2,000 students take Dutch courses there. In total, several thousand Indonesians study Dutch as a foreign language. Owing to centuries of Dutch rule in Indonesia, many old documents are written in Dutch. Many universities therefore include Dutch as a source language, mainly for law and history students. In Indonesia this involves about 35,000 students.

For how long have there been Dutch speakers in Indonesia?
