The flag of Singapore was adopted in 1959, the year Singapore became self-governing within the British Empire. It remained the national flag upon the country's independence from Malaysia on 9 August 1965. The design is a horizontal bicolour of red above white, overlaid in the canton by a white crescent moon facing a pentagon of five small white five-pointed stars. The elements of the flag denote a young nation on the ascendant, universal brotherhood and equality, and national ideals.

Yang di-Pertuan Negara is a title for the head of state in certain Malay-speaking countries, and has been used as an official title at various times in Brunei and Singapore.
