# Flag of Sudan

The flag of Sudan (علم السودان) was adopted on 20 May 1970 and consists of a horizontal red-white-black tricolour with a green triangle at the hoist. The flag is based on the Arab Liberation Flag of the Egyptian Revolution of 1952.
Whereas there is no fixed order for the Pan-Arab Colours of black, white, red, and green, flags using the Arab Liberation Colours (a subset of the Pan-Arab Colours) maintain a horizontal triband of equal stripes of red, white, and black, with green being used to distinguish the different flags from each other by way of green stars, Arabic script, or, in the case of Sudan, the green triangle along the hoist. In the original Arab Liberation Flag, green was used in the form of the flag of the Kingdom of Egypt and Sudan emblazoned on the breast of the Eagle of Saladin in the middle stripe. For 13 years from Sudan's independence in 1956 to the 1969 military coup of Gaafar Nimeiry, Sudan used a tricolour flag of blue-yellow-green.
The flag was designed by Abdel Rahman Ahmed Al-Jali [ar], and was selected after a national competition.

## Design
### Symbolism

According to World Flags 101:
   Red, white, black and green are called the pan-Arab colours and have been historically linked to the Arab people and Islamic religion for centuries. The colours stand for Arab unity and independence. The red stripe represents Sudan's struggle for independence and many other struggles, and the sacrifices of the country's martyrs. The white represents the people, light and optimism. It also represents the White Flag League which was a nationalist group that rose up against colonial rule in 1924. The black represents Sudan; in Arabic, 'Sudan,' means 'land of the black people.' It also represents the black flag of nationalists who fought colonial rule during the Mahdist Revolution, late in 19th century. Green represents Islam, agriculture and the prosperity of the land.

## Historical flags
### Flags of the Mahdists

In 1881, at the beginning of the Mahdist War, self-proclaimed Mahdi, Muhammad Ahmad appointed Abdallahi ibn Muhammad as one of his four caliphs and handed him a black flag. Abdallahi used his black flag to recruit Baggara Arabs and other tribes from the west. The other caliphs used different coloured flags. The black horizontal stripe in the current Sudanese flag is a reference to this Mahdist-era black flag.
* Flag used during the Mahdist Revolt and in Mahdist Sudan (1881–1899)
* Banner used by the Mahdist Army; captured at Omdurman in 1898.
* The black standard was also used in Mahdist Sudan

### Anglo-Egyptian Sudan

Between 1899 and 1956, Anglo-Egyptian Sudan was administered jointly as a condominium by Egypt and the United Kingdom. The condominium did not have its own flag; instead the flag of Egypt and the flag of the United Kingdom were always flown together, with the British flag taking precedence.
A flag did exist as a rank flag for the British Governor General of the Sudan. In common with the rank flags of governors and commissioners of other British overseas territories, it consisted of a Union Flag defaced with a white disk bearing the territory's badge or coat of arms, surrounded by a wreath of laurel. As no badge or coat of arms existed for Anglo-Egyptian Sudan, the disk instead contained the words "GOVERNOR GENERAL OF THE SUDAN".
At the Afro–Asian Conference held between 18 and 24 April 1955, Sudan was represented by a white flag bearing the name "SUDAN" in red capital letters.

### Republic of Sudan (1956–1969)

Upon the independence of Sudan from Anglo-Egyptian rule on 1 January 1956, Sudan adopted a blue-yellow-green tricolour as its national flag. This flag was designed by the poet Macki Sufi and remained in use until 1970, when the current flag was adopted. The colours of the flag represented the River Nile (blue), the Sahara (yellow) and farmlands (green). They were chosen as they were neutral between ethnic groups and political parties.
Use of this flag resurfaced during the 2018–19 Sudanese protests.

### Democratic Republic of the Sudan (1969–1985)
