The flag of Indonesia consists of a horizontal red stripe over top of an equally sized horizontal white stripe. The red stripe symbolizes blood and represents the human body. The white stripe represents the soul and the spirit. When you put these colors together, the red and white represent a complete human being.
The Indonesian flag was adopted on August 17, 1945. The first Indonesian flag was flown among Japanese occupation forces on the day Indonesia's independence was proclaimed. However, the previous Dutch colonial rulers didn't recognize Indonesian independence until December 27, 1949. In 1922 the Indonesian flag was used by activists seeking Indonesian independence from Dutch colonial rule and was later flown in 1928, by nationalists on the island of Java to represent the Indonesian campaign for independence. The Indonesian flag is based on a banner believed to have been flown in the late 13th century by the Majapahit Empire.
