The presence of foreign Muslims in Indonesia does not, however, demonstrate a significant level of local conversion or the establishment of local Islamic states.[9]:3 The most reliable evidence of the early spread of Islam in Indonesia comes from inscriptions on tombstones and a limited number of travellers’ accounts. The earliest legibly inscribed tombstone is dated AH 475 (AD 1082), although as it belongs to a non-Indonesian Muslim, there is doubt as to whether it was transported to Java at a later time.
