Flag of Sudan
The flag of Sudan used since 20 May 1970 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. Upon gaining independence in 1956, Sudan, adopted a horizontal tricolour of blue, yellow and green. This flag was abandoned after the 1969 military coup of Gaafar Nimeiry.
Flag history
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.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 the Republic of Sudan from Anglo-Egyptian rule on 1 January 1956, Sudan adopted a blue-yellow-green tricolour as its national flag.The 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, the Sahara and farmlands. They were chosen as they were neutral between ethnic groups and political parties.
Use of this flag resurfaced during the 2018–19 Sudanese protests. The president of the Transitional Sovereignty Council, Abdel Fattah al-Burhan, proposed readopting the blue-yellow-green tricolour in December 2025 in the midst of the Sudanese civil war (2023–present).

Democratic Republic of Sudan (1969–1985) and Republic of Sudan (1985–present)
Following a coup d'état in May 1969, the country was renamed the Democratic Republic of Sudan and a competition was held to design a new flag. The winning entry was designed by artist based on pan-Arab colours and was adopted as the national flag in May 1970.Whereas there is no fixed order for the Pan-Arab Colours of black, white, red, and green, flags using the Arab Liberation 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.
