Based on the account given in Hikayat Merong Mahawangsa (also known as the Kedah Annals), the Sultanate of Kedah started in year 1136 when King Phra Ong Mahawangsa converted to Islam and adopted the name Sultan Mudzafar Shah. However, an Acehnese account gave a date of 1474 for the year of conversion to Islam by the ruler of Kedah. This later date accords with an account in the Malay Annals where a raja of Kedah visited Malacca during the reign of its last sultan seeking the honour of the royal band that marks the sovereignty of a Muslim ruler.[1]
