History
The relations between ancient Indonesia and Singapore dated back from the period of ancient kingdoms, the straits region was part of Srivijaya’s realm back in 7th century. The Nagarakretagama, a Javanese eulogy written in 1365 during Majapahit era, also referred to a settlement on the island called Temasek ('Sea Town' in Old Javanese, spelt Tumasik).
In 1299, the ruler of Palembang, Sang Nila Utama, established the Kingdom of Singapura in Temasek. In the mid 1390s, a Palembang prince, Parameswara, fled to Temasek after being deposed by the Majapahit kingdom. During the 14th century, Singapore was caught in the struggle between Siam (now Thailand) and the Java-based Majapahit Empire for control over the Malay Peninsula.

Why this record matters
