The national flag of the Socialist Republic of Vietnam (Vietnamese: Quốc kỳ nước Cộng hoà xã hội chủ nghĩa Việt Nam), previously presenting the Democratic Republic of Vietnam, was designed in 1940 and first used during a failed communist uprising against the French colonialists in Cochinchina that year. The red background symbolizes revolution and bloodshed. According to a poem Tiến wrote, the red background came to represent the blood of the people, whilst the yellow foreground came to represent "the colour of our people’s skin" which was written during times of oppression from Japanese rule. According to Đức, yellow was chosen to represent Vietnam while the red background was inspired by the flag of the Communist Party and represents revolution. The National Assembly voted unanimously to adopt the flag on 2 March 1946.
The red background symbolizes revolution and bloodshed. The golden star symbolizes the soul of the nation and the five points of the star represents the five main classes in Vietnamese society—intellectuals, farmers, workers, entrepreneurs, and soldiers.
