This article relates about the Buddhist culture in Maldive! But how and why there have been a culture change is not clear by looking at this paragraph below
The year 1153 C.E. proved to be a great turning point
for the religion of those islands. According to a
legend related in the chronicle Tarikh, Sheik Yusuf
Shams-ud-din arrived in the Islands and exorcised the
spirits said to have possessed the King Theemugy Maha
Kalaminja, a Buddhist.
With relating to the highlighted sentence above, and looking at the history of Maldive this is what have happended! Mohamed Ibn Batuta, a Moroccan traveller who visited the Maldives in the 14th century recorded an interesting legend on how the country converted to Islam. Abul Barakaath Yoosuf Al Barbary, an Islamic scholar, visited the Maldives during a time when people lived in fear of the “Rannamaari”, a sea-demon,
who came out of the sea once a month threatening to destroy everything unless a virgin was sacrificed. The unfortunate young girls were chosen by lot, had to stay in a temple near the seashore
and were found raped and dead in the morning. The daughter of the house he was staying at had been selected to be the victim and he decided to save her. Disguised as a girl he spent the night in the temple reciting continuously from the Holy Quran
. In the morning when people went to find out the fate of the chosen girl they were amazed to find him alive and still reciting the Quran.
When the King found out that the demon had been defeated through the power of the Holy Quran
he embraced Islam and ordered all the subjects to follow him. So that is how then the king ordered his courtiers to do likewise!
And Also looking at this paragraph
He promptly converted to Islam
and ordered his courtiers to do likewise. In a short
time all the inhabitants of the islands had changed
their religion. In this way the Maldives lost its
ancient culture built up over more than a thousand
years and with it, Buddhism.
This is how the Buddhist Culture faded away and many Maldivians converted to Islam!
