What are the World’s Most Interesting Flags?

I am not saying this as i am holding the nationality of the same..but since dawn this flag particularly has been a fascinating and unique for me regardless of the others..it was unique in design and the marking of it has its own rich history and culture behind it. also, the thing to consider is -the flag carrier does not have any independence day.

My apologies, usually I do not copy-paste from other links or sites. Maybe I would extract the whole idea out of it, squeeze the juice out of it, and convey the message. But this is too complicated and I cannot alter the formula of it. So I had to copy from the other source.

The following are taken from Wikipedia in summery:- let’s generalize

The national flag of Nepal (Nepali: नेपालको झण्डा) is the world’s only non-quadrilateral national flag. The flag is a simplified combination of two single pennons, the vexillological word for a pennant. Its crimson red is the colour of the rhododendron, the country’s national flower. Red is also the sign of victory in war.

The blue border is the colour of peace. Until 1962, the flag’s emblems, the sun and the crescent moon, had human faces. They were removed to modernize the flag.

The flag was adopted, with the formation of a new constitutional government, on December 16, 1962. The individual pennants had been used for the preceding two centuries and the double pennant since the 19th century. The flag borrows the basic design from the original design, which has been in use for more than 2,000 years

There is a precise description of the Nepalese national flag in the Constitution of the Kingdom of Nepal, Article 5, Schedule 1, adopted 9 November 1990.

National Flag

(A) Method of Making the Shape inside the Border

(1) On the lower portion of a crimson cloth draw a line AB of the required length from left to right.

(2) From A draw a line AC perpendicular to AB making AC equal to AB plus one third AB. From AC mark off D making line AD equal to line AB. Join BD.

(3) From BD mark off E making BE equal to AB.

(4) Touching E draws a line FG, starting from the point F on line AC, parallel to AB to the right-hand-side. Mark off FG equal to AB.

(5) Join CG.

(B) Method of Making the Moon

(6) From AB mark off H making AH equal to one-fourth of line AB and starting from H draw a line HI parallel to line AC touching line CG at the point I.

(7) Bisect CF at J and draw a line JK parallel to AB touching CG at point K.

(8) Let L be the point where lines JK and HI cut one another.

(9) Join JG.

(10) Let M be the point where line JG and HI cut one another.

(11) With centre M and with a distance shortest from M to BD mark off N on the lower portion of line HI.

(12) Touching M and starting from O, a point on AC, draw a line from left to right parallel to AB.

(13) With centre L and radius LN draw a semi-circle on the lower portion and let P and Q be the points where it touches the line OM respectively.

(14) With centre M and radius MQ draw a semi-circle on the lower portion touching P and Q.

(15) With centre N and radius NM draw an arc touching PNQ [sic] at R and S. Join RS. Let T be the point where RS and HI cut one another.

(16) With Centre T and radius TS draw a semi-circle on the upper portion of PNQ touching it at two points.

(17) With centre T and radius TM draw an arc on the upper portion of PNQ touching at two points.

(18) Eight equal and similar triangles of the moon are to be made in the space lying inside the semi-circle of No. (16) and outside the arc of No. (17) of this Schedule.

(C) Method of making the Sun

(19) Bisect line AF at U and draw a line UV parallel to line AB touching line BE at V.

(20) With center W, the point where HI and UV cut one another and radius MN draw a circle.

(21) With center W and radius LN draw a circle

(22) Twelve equal and similar triangles of the sun are to be made in the space enclosed by the circles of No. (20) and of No. (21) with the two apexes of two triangles touching line HI.

(D) Method of Making the Border

(23) The width of the border will be equal to the width of TN. This will be of deep blue color and will be provided on all the sides of the flag. However, on the five angles of the flag, the external angles will be equal to the internal angles.

(24) The above mentioned border will be provided if the flag is to be used with a rope. On the other hand, if it is to be hoisted on a pole, the hole on the border on the side AC can be extended according to requirements.

Explanation: The lines HI, RS, FE, ED, JG, OQ, JK, and UV are imaginary. Similarly, the external and internal circles of the sun and the other arcs except the crescent moon are also imaginary. These are not shown on the flag.

Aspect Ratio:

According to the stated geometric construction law, the circumscribing rectangle has an irrational ratio of:


≈ 1:1.21901033… ( A230582).


This ratio is the least root of the quartic equation:



And arises from the addition of the blue border after construction of the red field. The bounding rectangle of the red field alone has the rational aspect ratio 3:4 (=1:1.333…).

The flag of Nepal is the only national flag in use with an aspect ratio less than one (meaning it is taller than it is wide)
