The legend of Merong Mahawangsa.
The Kedah Annals claimed that Merong was a descendant of Alexander the Great or Dhul-Qarnayn.
According to the Kedah Annals, Merong was a fighter and ruler of an unknown kingdom. He travelled around from kingdom to kingdom, but mostly stayed in Rome. One day, he left Rome to do some trading in China. But then, after he passed the Arabian Sea, he was suddenly attacked by a legendary giant phoenix called Garuda, that destroyed most of Merong's fleet. They fled to the nearest land, which is Bujang Valley, where they settled and founded the kingdom of Langkasuka.
Merong was the original ruler of Langkasuka before he made his son, Merong Mahapudisat, the king. He returned to Rome, leaving his son to rule after. His fate was unknown, as some say that he died on his way to Rome. His son ruled Langkasuka, along with his descendants, until Phra Ong Mahawangsa converted into Islam and changed the Kingdom of Langkasuka into the Sultanate of Kedah. He also changed his name into Sultan Mudzafar Shah.
Later, the salutation for the king of Langkasuka changed into the Sultanate of Kedah. The name 'Langkasuka' can be divided into two parts: for which 'Langka' meant 'the land of glory' in Sanskrit, while 'suka' means 'joy' or 'happiness'.
