Viraraghava copper plate

Viraraghava copper plate (c. 1225 CE) is a medieval Vattezhuthu inscription from central Kerala, southern India, describing the several concessions made by Viraraghava, the ruler of "Makotaiyar Pattinam" (the port of Kodungallur), to Syrian Christian merchant Iravikorttan, who was the leader of Manigramam at the time of receiving these concessions.

The provisions include the Title of Cheraman Loka Maha Perum Chetty, multiple commercial rights and princely privileges, such as "the Rights of the Manigramam Merchant Guild", Sovereignty and tax free status over port city of Makottiyarpattinam, various monopolies, article brokerages and the right to use slave labour. The record is currently in possession of the Syrian Christian community in Kottayam.
