Historical Trajectory
Phase I: Rise
Langkasuka is believed to have been founded around the 1st to 2nd century AD on the Malay Peninsula, possibly by descendants of the Mauryan emperor Ashoka. According to the Kedah Annals, the kingdom was established by Merong Mahawangsa. Archaeological evidence near Yarang, Pattani, Thailand supports this region as the kingdom's probable heartland, making it one of the earliest Indianized polities in the Malay world.
Phase II: Zenith
At its height, Langkasuka functioned as a significant Indianized kingdom integrating Hindu and Buddhist religious traditions with Malay political culture. It maintained diplomatic contact with China, as recorded in Chinese historical sources that document king Bhagadatta dispatching envoys to the Chinese imperial court. It coexisted and interacted with neighboring Old Kedah as one of the earliest states of the Malay Peninsula.
Phase III: Decline
Langkasuka gradually declined over the course of the medieval period, eventually disappearing by the 15th century. The rise of competing Malay sultanates and the spread of Islam across the peninsula transformed the political and religious landscape, supplanting earlier Hindu-Buddhist polities. No precise account of its final collapse survives, but it ceased to function as a distinct kingdom by the 1500s.
