With 20 different designs since 1709, Afghanistan’s national flag has had more changes since the start of the 20th century than any other country in the world. The colors black, red, and green appeared on most Afghanistan flags and it’s widely believed that black signifies the past, red is for the blood shed for independence, and green can represent either hope for the future, agricultural prosperity, or Islam.
The current Afghanistan flag was adopted by the Islamic Republic of Afghanistan in 2004, which describes the flag this way: “The flag of Afghanistan shall be made up of three equal parts, with black, red and green colors juxtaposed from left to right vertically. The width of every color shall be half of its length, and at the center of which the national insignia shall be located. The national insignia of Afghanistan shall be comprised of an emblem and a pulpit in white color—at the two corners of which are two flags, inscribed in the top middle the holy phrase “There is no God but Allah and Mohammad is his Prophet, and Allah is Great.” This shall be inscribed and superseded on rays of a rising sun, and in its lower part, the year 1919 in the solar calendar, and the word “Afghanistan” encircled on two sides by sheaves of wheat shall be inscribed. The law shall regulate the use of the flag and insignia.”
