The national flag of Vietnam, formally the National Flag of the Socialist Republic of Vietnam (Vietnamese: Quốc kỳ nước Cộng hoà xã hội chủ nghĩa Việt Nam),[1][2] locally recognized as the golden-starred red banner (cờ đỏ sao vàng)[a] or the Fatherland flag (cờ Tổ quốc), was designed in 1940 and used during a failed communist uprising against the French colonialists in Cochinchina that year.

[4] The initial incarnation of the flag was used by the Viet Minh, a communist-led organization created in 1941 to oppose Japanese occupation.

According to Article 141 of the 1992 constitution: "The National Flag of the Socialist Republic of Vietnam is rectangular in shape, its width is equal to two thirds of its length, in the middle of fresh red background is a bright five-pointed golden star".

The flag first appeared in the Cochinchina uprising (Nam Kỳ Khởi nghĩa) of 23 November 1940, against French rule in southern Vietnam.

[10] Tiến, who was born in the northern village of Lũng Xuyên, was unknown to the Vietnamese public before Tùng's research was published.

In April 2001, Vietnam's Ministry of Culture reported that there was no documentation to support the claim that Tiến designed the flag.

In April 1940, the flag was approved by Phan Văn Khỏe, the Communist party chief of Mỹ Tho.

[14] The Viet Minh proclaimed it a "national flag" on 17 August 1945, at a meeting held in the village of Tân Trào in the North.

[15] When the Japanese surrendered at the end of World War II, the Viet Minh entered Hanoi and proclaimed the "Democratic Republic of Vietnam" on 2 September.

On 5 September, DRV President Ho Chi Minh signed a decree adopting the Vietminh flag.

On 30 November 1955, the flag's design was modified slightly to make the star smaller and its rays straighter.

The Vietnamese lawmakers never nominate the standardized color schemes, and flags with different color shades are physically and digitally displayed by both civilians and state media as long as they obey the "red background with a centered yellow star" symbolism.Traditional images show the Trung sisters wearing yellow turbans during their revolt against North (China) in AD 40.

[19] The French, who gradually gained control of Vietnam in the late 19th century, flew the national flag of France.

In March 1945, the Japanese deposed the French colonial authorities and proclaimed an Empire of Vietnam with Bảo Đại as emperor.
