# Flag of Indonesia

The national flag of Indonesia is a simple 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 Proklamasi Street (formerly Pegangsaan Timur Street) in Jakarta, and again when the Dutch formally transferred sovereignty on 27 December 1949. The design of the flag has remained unchanged since.
The flag of Indonesia is graphically similar to the flag of Monaco, with a slight difference in the shade of red, and ratio of its dimensions. The flag of Poland has similar dimensions but has the colours reversed: white on top and red on the bottom. In both Monaco's and Poland's flags, the reds are of a slightly darker shade than that of Indonesia. The flag of Singapore has exactly the same dimensions as Indonesia's, but supplemented with a white crescent moon and five stars in a pentagram at the upper left corner of the flag, of which the red is of a slightly lighter shade.
The "Naval Jack of Indonesia" is reserved for sole use by the Indonesian Navy. It flies from the jackstaff of every active Indonesian warship while anchored or moored pierside and on special occasions. The design of the jack is described as nine alternating stripes, consisted of five red and four white stripes. It is nicknamed Sang Saka Merah Putih, lit. 'The Heirloom Red-White'. The naval jack dates to the age of Majapahit Empire. This empire, renowned for its great maritime strength, flew similar jacks on its vessels.

## History

The flag's colours are derived from the banner of the 13th century Majapahit Empire. However, it has been suggested that the red and white symbolism can trace its origin to the older common Austronesian mythology of the duality of Mother Earth (red) and Father Sky (white). This is why these colours appear in so many flags throughout Austronesia, from Tahiti to Madagascar. The earliest records of the red and white panji or pataka (a long flag on a curved bamboo pole) can be found in the Pararaton chronicle; according to this source, the Jayakatwang troops from Gelang-Gelang hoisted the red and white banner during their invasion of Singhasari in the early 12th century. This suggests that even before the Majapahit era, the red and white colours were already revered and used as the kingdom's banner in the Kediri era (1042 – c. 1222).
Red and white textile colouring was available in ancient Indonesia. White is the natural colour of woven cotton fabrics, while red is one of the earliest natural dyes, acquired either from teak leaves, the flowers of Averrhoa bilimbi, or the skin of mangosteen fruits.
It was not only the Javanese kingdoms that used red and white. The battle flag of King Si Singamangaraja IX of Batak lands bore an image of white twin swords called piso gaja dompak against a red background. During the Aceh War of 1873–1904, Aceh warriors used a battle flag with the image of a sword, star and crescent, sun, and some Quranic script in white on a red background. The red and white flag of the Buginese Bone kingdom in South Sulawesi is called Woromporang. The Balinese Badung (Puri Pamecutan) royal banner is red, white, and black. Prince Diponegoro also used a red and white banner during the Java War (1825–1830).
In the early 20th century, these colours were revived by students and then nationalists as an expression of nationalism against the Dutch. A precursor design was first seen on the cover of a Dutch magazine titled Gedenkboek 1908-1923 run by the Perhimpoenan Indonesia ('Indonesian Association'). Compiling 13 letters written by its anonymous members, it had a sinister hoisted flag of a red and white stripe superimposed with the head of a banteng facing away from the hoist. The modern red and white flag sans banteng head was first flown in Java in 1928, it was quickly prohibited under Dutch rule. It became the flag adopted by the Kesatuan Melayu Muda to symbolise Malay nationalism against European colonialism. Upon Indonesia's declaration of independence on 17 August 1945, it was adopted as the national flag, and has been in use ever since. After Indonesia's independence was recognized, Monaco, which had a similar flag, filed a complaint which was largely ignored.

### Hotel Yamato incident

The flag featured in a well-known incident during the Indonesian War of Independence when during the lead-up to the Battle of Surabaya in late 1945, Indonesian youths removed a colonial Dutch flag flying over the Yamato Hotel, tore off the blue strip and re-hoisted it as an Indonesian flag. The hotel was subsequently renamed briefly as Hotel Merdeka, meaning "independence hotel".

## Name

According to Article 35 of the 1945 Constitution, the official name of the flag is Sang Saka Merah-Putih. The flag is commonly called Bendera Merah-Putih ('Red-and-White Flag'). Occasionally, it is also called Sang Dwiwarna ('The Bicolour'). Sang Saka Merah-Putih refers to the historical flag called Bendera Pusaka ('Heirloom Flag') and its replica. The Bendera Pusaka is the flag that was flown in front of Sukarno's house after he proclaimed Indonesia's independence on 17 August 1945. The original Bendera Pusaka was sewn by Fatmawati and was hoisted every year in front of the Merdeka Palace during the independence day ceremony. It was hoisted for the last time on 17 August 1968. Since then it has been preserved and replaced by a replica since the original flag was deemed to be too fragile.

## Symbolism

Several opinions have been expressed on the meaning of the red and white in the Indonesian flag. 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.
As Sukarno said:
   Red is the symbol of courage, White is the symbol of purity. Our flag has been there for 600 years.
The colours are the same as those used in the flag of the Majapahit.
