Langkasuka is one of the oldest named states of the peninsula, known to the Chinese from the sixth century (Liang shu; embassies in 515, 523, 531 and 568) and struck by the Cholas in 1025 as Ilangasoka.
Its centre is usually placed at the banked and moated site of Yarang behind the Patani lagoons (about 0.9 square kilometres, 44 brick stupa mounds, Pallava-script votive tablets, a bronze Avalokitesvara), but the excavated material begins only in the seventh century and the site's life in the twelfth is not shown. The Zhufan zhi describes it as a working country a generation later, so something stands there in 1200. No ruler, date or event is recorded.

Where the sources disagree
- The campaign board (yarang-langkasuka, powers.txt) says Langkasuka is 'fading out of the sources' by 1200. The Zhufan zhi of about 1225 still describes it, so 'fading' is a modern impression, not a recorded decline.
Evidence: A site and a name; no ruler or event near the date.
"The campaign board" is OMNIA's working map. These notes record where its earlier claims were checked against the sources.
On the map: Drawn on the modern provinces; the real extent in 1200 is unknown.
Primary sources for this realm
Chronicles, registers, sagas and inscriptions written in or near 1200 that cover this entry. Each has its own page with editions, translations and where to read it.
- The Grahi (Chaiya) Buddha inscription and the Tambralinga records, Various (the officers of Grahi and the kings of Tambralinga), edited by George Coedes (the Chaiya bronze Buddha inscription 1183; the Nakhon Si Thammarat records 13th century; edited 1929, revised 1961). The peninsula in 1200 has one near-contemporary dated text: the Old Khmer inscription on the base of a bronze Buddha from Wat Hua Wiang at Chaiya, dated 1183, which records the image's casting by order of the mahasenapati Galanai, governor of Grahi, under the king Srimat Trailokyaraja Maulibhusanavarmadeva, a name that is argued to be either a Malayu (Srivijaya) overlord or a local king.
