The Korean national flag is called TaeGukKi or TaeKukKi. The meaning of Korean National Flag is very philosophical. The origin comes from the old oriental philosophy called the theory of Um-Yang, in chinese pronounciation Yin-Yang. Yin means dark and cold, while Yang means bright and hot. This represents the dualism of the cosmos. The harmonious state of the movement of yin and yang is called TaeGuk which is also the name of the Korean national flag, TaeGuk-Ki. Ki means a flag. The upper half circle, red, of TaeGuk means yang and the lower half circle, blue, means Eum. They stand for the state of harmony of yin and yang.
The symbols, called Kwe, in the four corners, mean the principle of movement and harmony. Basically, each Kwe consists of three bars that can be either broken or unbroken bars. A broken bar stands for yin while an unbroken bar stands for Um. Here are the four Kwe, their names, and what they sybolize.
| Kun | Heaven | |
| Yi | Fire | |
| Kam | Water | |
| Kon | Earth |
The following illistrates the proper way to hang the Korean Flag.

The Korean flag was slightly changed in 21 February 1984, but the disposition
of the ying yang seems strange (left blue, right red instead red over blue). I
checked some plates pre-1984 and in all the plates the flag is red over blue.
The flag was not adopted until 1950 but was in use de facto after 1945; perhaps
the design posted is derived from the designs used from 1945-50,

I saw on TV recently what seems to be the first flag of the Republic of
Korea. This was on the TV show M*A*S*H, a show from the 1970s, but set in the
times of the Korean War. The flag references they have (the show is set on a US
Army medical base) are quite accurate (ie a 48-star flag flies over the
compound, along with a UN and S. Korean flag), so I don't doubt the authenticity
of the flag. The flag was shown in a good shot in the episode "Welcome to
Korea" (season opener of season 5), and I attach it as KR-1952.GIF (because
it was referenced in the episode that it takes place shortly before September
19, 1952). The major differences: the four corner elemnts are smaller and closer
to the corner, and the ying-yang is on its side. The ying-yang also appeared to
be drawn differently, but I couldn't get a clear enough shot of it to tell for
sure how it appeared.

I just opened by chance my Crampton's Complete Guide to Flags, 1990, just on the page where Korea is and noticed a sentence that did not sound familiar.
So, it says: South Korea has kept the flag of the former Kingdom of Korea, althought it has been modified. ... and the trigrams (kwae) are reduced from eight to four."
So, what was the flag of the Kingdom of Korea with 8 kwaes? What the change
occured?

This is perhaps the oldest representation of the South Korean flag, along
with an article which appeared in a local, Seoul newspaper.

In 'The International Geography', London, 1911, I found this flag - the old flag of Korea, before it was occupied by Japan in 1905. Korea ceased to exist until 1947, after which a lot of things happened.
However the 'old Korean flag' differs in several respects from the present South Korean flag:
I scanned the flag. Perhaps some Korean FOTWer can tell us more about the 8
kwaes?
Jarig Bakker, 14 January 1999
That's IT! That's the Korean flag I saw in the episode of M*A*S*H! (I
coudln't get a good enough view of the ying-yang symbol on my VCR, but that's
definitely what I saw!) I have no reason to doubt the fact that this flag was
used in Korea during the war - I don't think that they changed their flag
suddenly in 1947, but it probably took time. I was pretty sure the "kwae"s
were black on the flag I saw, however, but that is the flag!

I think the number 8 comes naturally (2x2x2). Either of the three lines in a trigram can be either yin (- -) or yang (---). According to my I Ching, the symbolism is this:

I have a photocopy of an article by H.G. Ströhl called "Wappen und
Flagge von Korea" in Herold, Oct. 1893, nr. 10, XXIV. It
shows two flags. The first is labeled "Koreanische Flagge" and is
like the modern flag, but the yin-yang - sign is much more intricate (like
the GIF Jarig posted) and the upper part is blue, the lower blue. According
to the text normally only the 4 main kwae appear on the flag, most of
the time blue. It also says that the arrangement of the kwae is not always
the same. The second flag shown is the one flown at the Royal Korean
Consulate in Hamburg, and has 8 kwae, coloured yellow. The yin-yang -
sign is like on the modern flag, but rotated 90 degrees anti-clockwise. I
have some doubts if the arrangement of these 8 kwae is correct, since
two opposing kwae are not each others inversion. On the image of an
old Chinese wind rose shown in the article they are inverted, so maybe that
arrangement is more correct.
Mark Sensen, 14 January 1999
It is interesting to note that the flag called the Royal Korean Consulate flag has a different arragnement of the trigraphs. I have noticed that the Koreans are very exact in describing the layout of their flag (10:15). Yet the flag that is flown on holidays is not of the same proportions as that shown in the official description of their flag, the main difference being the addition of extra white to the field of the flag on the side away from the flag pole. The additional material gives the flag the same length as the US flag (10:19).
The ordering of the trigrams in the tooth edge flag matches that of the
Hou Tian (latter heaven) ordering of the trigrams of the Chinese Yi Ching.

The I Ching , the "Book of Changes", mentioned by Ole consists of the 64 combinations you get by combining the 8 kwae and was and is used by fortune-tellers to give answers to questions. [Source: Hans Biederman, "Prisma van de symbolen", 1991/1996, Dutch translation of "Knaurs Lexicon der Symbole"]
The flag was first hoisted 22 August 1882 when the first ambassadors were
sent to Japan, an adopted officially 27 January 1883. Korea was occupied by
Japan in 1905 and annexed on 22 August 1910. After the liberation the
country was divided along the 38th degree of latitude. The Republic of Korea
was established in the southern (American) zone on 15 August 1948, which
readopted the flag in the same year when the colours and shape were
established by law. On 25 January 1950 the flag was adopted officially when
the kwae were revised slightly. In 1984 the lay-out was again
slightly changed. [Sources: Barraclough, "Flags of the World",
1981; Whitney Smith, "Spectrum Vlaggenboek", 1975; Kent Alexander,

This was done eight months before independence by General MacArthur.

I forgot to mention the flag is known as T'aeguk or "Great
Polarity".

During the Japanese colonial rule (1910-1945) the Korean t'aeguk circle flag was prohibited to use.
The Japanese governor of Korea's flag was used that is light blue flag with Japanese national flag (hinomaru) in a canton like British blue ensign despite of a different color shade. The canton is one fourth of whole flag in size. The light blue stands for justice, fairness and philanthropy.
1910-1883
Korea used a similar flag to present flag. The t'aeguk is longer than current one and coloue was reverse:blur over red. The black four trigrams are placed in differently: There were two broken and one unbroken lines in upper left/ three unbroken lines in upper right/three broken lines in bottom left/one broken and two unbroken lines in bottom right.
1876-1854
An old Japanese flag book published in 1876/1854 shows square yellow flag
with red rugged border as a Korean King's standard. The flag bears a green
dragon having red tongue and gray clouds.
