Pannai, Panai or Pane was a Buddhist kingdom located on the east coast of Northern Sumatra that existed between the 11th and 14th centuries.
Because surviving inscriptions and historical records of this period are scarce, the kingdom is among the least known political entities in Indonesian history.
In Armenian-language travel records, Indian City Names and Persian Suburbs, Pane is referred to as the port where much high-quality camphor can be found.
This inscription mentioned Pannai with its water ponds was among the conquered cities during Rajendra Chola I campaign against Srivijaya.
[5] There is also a mention of the word kuti in the inscription which probably refer to the Buddhist temple nearby, called as biaro by current local community.
In other words, historian conclude that Pannai was probably a small kingdom ruled by a king with honorific title Haji, which was the adherent of Buddhism.
[5] Three centuries later, the name of the kingdom reappeared in Javanese source, the Nagarakretagama, written by Mpu Prapanca from Majapahit Empire dated 1365 (or 1287 Saka year).
These states includes Palembang, Teba, Kandis, Kahwas, Minangkabau, Siak, Rokan, Kampar, Pane, Kampe, Haru, Mandailing, Tamiyang, Perlak, Padang Lawas, Samudra, Lamuri, Batan, Lampung and Barus, all were under Singhasari influence later inherited by its successor state, Majapahit.
[5] In 1846 Franz Junghuhn, a geology expert under Commission of Dutch East Indies authority reported the discovery of temple compound in Padanglawas area, upstream of Barumun River.
This vast and empty savanna-like area dotted with Biaro, a local name for temple, obviously derived from Sanskrit vihara.
[7] It is suggested that the center of Pannai Kingdom was located in the more fertile area and much closer to maritime trade route of Malacca Strait, which pointing into the estuarine of Panai and Barumun river.
