Aru

Aru, or Haru, was a kingdom on the eastern coast of North Sumatra, centred on Kota Rentang.

Majapahit gained control of Aru in 1339, and Ma Huan recorded its Muslim king and subjects in 1416. Pressed by Aceh, the court moved inland to Benteng Putri Hijau; the old port probably fell in 1539. Aceh's Iskandar Muda struck Aru in 1613, and its successor Deli became an Acehnese protectorate in 1632.
