Historical Background

Papua New Guinea (PNG) occupies the eastern half of the island of New Guinea; the western half is part of Indonesia. PNG was first settled between 50,000 and 60,000 years ago. Its harsh geography of mountains, jungles, and numerous river valleys kept many of the arriving groups isolated, giving rise to PNG’s ethnic and linguistic diversity. Around 500 B.C., Austronesian voyagers settled along the coast.
