bronze statue from Pamutung in Padang Lawas. One of a few artifact linked to Pannai Kingdom|left|271x271px The existence of this kingdom was first mentioned in
Thanjavur inscription written in
Tamil dated from 1025 and 1030. The inscription created by
Rajendra Chola I, king of Cholamandala kingdom,
Chola Dynasty, in South India, mentioned about
Chola invasion of Srivijaya. This inscription mentioned Pannai with its water ponds was among the conquered cities during Rajendra Chola I campaign against Srivijaya. Other than Pannai, the Chola invasion also claimed
Malaiyur,
Ilongasogam,
Madamalingam,
Ilamuri-Desam, and
Kadaram. The inclusion of Pannai together with other port cities being invaded during Chola campaign against Srivijaya suggested that Pannai was a member of the Srivijayan
mandala. The only local source mentioning the name
Panai is the Panai inscription, discovered by the
Biaro Bahal temple complex, in Padang Lawas regency, North Sumatra. The 10th line of the inscription contains the word
Panai. 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. The title of
haji accompanying the word
kuti indicates that there is a small kingdom ruled by a
haji or a lesser king, which was posthumously dedicated in the Bahal temple. 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. In ancient Indonesia, the title
haji or
aji refers to a regional ruler, a lesser king, a vassal, or a subordinate ruler in contrast to the paramount
Maharaja (
Chakravartin). To date, Panai inscription is the only remaining local primary historical source of the kingdom. Unfortunately much of the writings in this inscription is unreadable due to its poor condition. 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). In Nagarakretagama canto 13, Pane is mentioned as one of Sumatran kingdoms held under Majapahit influence. Javanese overlordship upon Malay states in Sumatra was probably initiated through
Singhasari's
Pamalayu expedition that pull Malayu
Dharmasraya into Singhasari mandala orbit. Therefore, all of Dharmasraya's vassal states were also recruited within Javanese Singhasari mandala. 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. ==Historical sites==
