In Kampong Pande, the tombstone of Sultan Firman Syah, the grandson of Sultan Johan Syah, has an inscription stating that Banda Aceh was the capital of the Kingdom of Aceh Darussalam and that it was built on Friday, 1 Ramadhan (22 April 1205) by Sultan Johan Syah after he defeated the Hindu and Buddhist Kingdom of Indra Purba whose capital was Bandar Lamuri. The establishment of further Islamic states in North Sumatra is documented by late 15th- and 16th-century graves including those of the first and second Sultans of Pedir; Muzaffar Syah, buried (1497) and Ma’ruf Syah, buried (1511). Aceh was founded in the early 16th century and would later become the most powerful North Sumatran state and one of the most powerful in the whole Malay archipelago.
