The national flag of Indonesia, which is known as Sang Saka Merah Putih (“The Red and White”) in Indonesian, is based on the flag of the 13th century Majapahit kingdom in East Java. The flag itself was introduced and hoisted in public at the Indonesian Independence Day ceremony, on 17 August 1945. The design of the flag has remained the same ever since. Red represents courage, while white represents purity of intent.
