古マタラム王国
The name of the Medang Kingdom was mentioned in the Laguna Copperplate Inscription of the Philippines' Tondo, dated 822 saka (c. 900 CE), discovered in Lumban, Laguna, Philippines. The discovery of the inscriptions, written in the Kawi script in a variety of Old Malay containing numerous loanwords from Sanskrit and a few non-Malay vocabulary elements whose origin is ambiguous between Old Javanese and Old Tagalog, suggests that the people or officials of the Medang Kingdom had embarked on inter-insular trade and foreign relations in regions as far away as the Philippines, and that connections between ancient kingdoms in Indonesia and the Philippines existed.
