Flag of Cambodia

Since around 1850, the Cambodian flag has featured a depiction of Angkor Wat in the center. The current flag, with a blue border and red central (the stripes are in the ratio 1:2:1) was adopted following Cambodia's independence in 1948. It was used until October 9, 1970, when a new flag was introduced for Lon Nol's Khmer Republic that lasted until the takeover of the Khmer Rouge in 1975. The subsequent state of Democratic Kampuchea, which existed from 1975 to 1979, used a red flag with a three-towered Angkor Wat design retained in yellow. The People's Republic of Kampuchea was established in 1979, after the Vietnamese invasion of Cambodia.

The Kampuchean National United Front for National Salvation (FUNSK) revived the flag adopted by the Khmer Issarak in the days of anti-French resistance for the new state. This flag had the same color pattern as the DK flag, but with a yellow five-towered Angkor Wat silhouette. When the PRK renamed itself as "State of Cambodia" (SOC) in 1989, the flag's lower half became blue. The UNTAC flag was used during the 1992-1993 transitional period along with the flag of the SOC within Cambodia.

In 1993, the 1948 Cambodian flag was readopted. The current Cambodian flag, together with that of Afghanistan, hold the distinction of being the only two flags in the world to feature a building in their design. Red and blue are traditional colors of Cambodia.

The flag used today is the same as that established in 1948, although since then 5 other designs have been used. Almost all made use of the image of the temple of Angkor Wat in one form or another. This famous temple site, which dates from the 12th century, was built by the Mahidharapura monarchs. It has 5 towers, but these were not always all depicted in the stylised version used on flags. The monarchy was restored in September 1993, the 1948 flag having been readopted in June of that year.
