The national flag of Indonesia is bicolor, with two horizontal bands, red (top) and white (bottom) with an overall ratio of 2:3. It was introduced and hoisted in public during the proclamation of independence on 17 August 1945 at 56 Jalan Proklamasi (formerly Jalan Pegangsaan Timur) in Jakarta, and again when the Dutch formally transferred sovereignty on 27 December 1949. == History == The flag's colours are derived from the banner of the 13th century Majapahit Empire. One of them is that the red stands for courage, while the white stands for purity. Another opinion is that red represents the human body or physical life, while white represents the soul or spiritual life; together they stand for a complete human being.
