Laguna Copperplate: Earliest Writing from the Philippines

The Laguna Copperplate Inscription, the oldest known written document found in the Philippines, recorded the pardon of debts owed by the Honourable Namwaran and his family by the Commander of Tundun on April 21, 900 AD. The copper plate was discovered in 1989 near the mouth of the Lumbang River in Laguna province, Luzon, buried in sand along the riverbank. Written in the Kawi script used across maritime Southeast Asia, the text is composed in Old Malay with Sanskrit loanwords, and it documents a legal transaction in which Namwaran, his children Lady Angkatan and Bukah, were formally released from their obligations by the representative of the Lord Minister of Pailah, Jayadewa. The inscription revealed a sophisticated pre-colonial legal and trade network linking the Philippines to the broader Southeast Asian world, contradicting the colonial-era assumption that the Philippine archipelago was isolated from regional civilization before Spanish contact. The document demonstrates that the inhabitants of Luzon in the tenth century maintained formal legal systems, used written contracts, employed a commercial vocabulary borrowed from Sanskrit-influenced trading languages, and participated in a network of political relationships that extended across the Malay world. The mention of Tundun has been identified by scholars as a reference to Tondo, a polity in what is now Manila that maintained trade relationships with China, Srivijaya, and the Majapahit Empire. The copperplate's significance extends beyond its content: it proves that literacy, legal codification, and international diplomatic relations existed in the Philippines at least six centuries before Ferdinand Magellan arrived in 1521.
