Many look-alike flags share a history. Countries that once belonged to the same empire or federation, or wanted to show they stood together, chose the same colours. Others are plain coincidence.
The closest pairs
In these pairs the colours and the layout match, and the difference is a shade, a mirror image or the proportions.
Chad and Romania arrived at the same flag separately. Romania has flown a blue, yellow and red tricolour since the 19th century, and Chad chose its flag in 1959. They became near twins in December 1989, when Romania removed the communist coat of arms from the middle of its flag. In 2004 Chad asked the United Nations to look into it, and Romania's president answered that the flag would not change.
Britannica calls the Indonesia and Monaco match a coincidence. Monaco's red and white come from the diamonds on its princely coat of arms, and Indonesia's from the Majapahit empire of medieval Java.
Flags that look like the US flag
The US flag has 13 red and white stripes and 50 stars on a blue corner. Two national flags copy that layout closely, and two more pairs share its colours and have a single star.
Liberia's likeness is deliberate. The colony was founded by an American society for freed slaves, and its flag was based on the US flag from the start. The 11 stripes stand for the 11 men who signed Liberia's declaration of independence in 1847. Puerto Rico's flag was made the same way: Puerto Rican revolutionaries in New York took the Cuban flag in 1895 and inverted its colours.
European flags that look alike
When Slovenia became independent in 1991, it added its coat of arms to tell its flag apart from Russia's and Slovakia's. The white, blue and red of all three are known as the Pan-Slavic colours, after the Russian flag.
African flags that look alike
Green, yellow and red, the Pan-African colours, were borrowed from the flag of Ethiopia. Ghana was the first newly independent African state to take them, in 1957, and many neighbours followed, so the same three colours turn up in different orders and with different stars.
Senegal and Mali share a flag because they were briefly one country, the Mali Federation of 1959 to 1960. Its flag had a small human figure in the middle; after the split, Senegal swapped the figure for a green star, and Mali dropped it in 1961. Two more African flags have their twins on other continents: Chad matches Romania, and Ivory Coast mirrors Ireland (both in the first table).
Arab flags that look alike
Red, white, black and green, the Pan-Arab colours, go back to the flag of the Arab Revolt against Ottoman rule during the First World War. Most flags in this group differ only by the emblem in the middle or the shape at the pole.
Bahrain cut its points to five in 2002, so that each one stands for one of the Five Pillars of Islam. Qatar's flag is the only national flag more than twice as long as it is tall.
More look-alikes in Asia, Oceania and the Americas
The two big groups here are old federations. Colombia, Ecuador and Venezuela were once united as Gran Colombia, and Honduras, Nicaragua and El Salvador kept the blue and white of the Federal Republic of Central America, which the five stars and five volcanoes recall.
Why so many flags look alike
Many look-alikes belong to a family: a set of flags that share colours or a layout on purpose. Once you can name the family, a flag you cannot place becomes a choice between a handful.
How to stop mixing them up
- Learn each pair together, side by side, and say the difference out loud: Chad is darker, Monaco is squarer, Senegal has the star.
- Name the family first. Red, white and black with something in the middle is almost always an Arab flag; then the middle tells you which.
- Look at the corner and the centre before the colours. Stars, shields and emblems split most pairs faster than shades do.
- For mirror pairs such as Mali and Guinea or Ireland and Ivory Coast, remember only which colour touches the pole.
- Test yourself without the answer in view. Paint the Flag makes you colour a flag from memory, which catches order mistakes, and Guess the Flag gives you one flag a day to name.
