Flag of Sudan
national flag of the Republic of the Sudan
The flag of Sudan (عَلَم السُّودَان) 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.
Begin with the source’s own compact description: “Flag of Sudan” is national flag of the Republic of the Sudan. The dossier treats that line as a proposition to test through Flag, Sudan and national, not as a finished interpretation.
Why this record matters
The phrase “national flag of the Republic of the Sudan” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 28, 2026. The linked authority identifier is Q102198. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1970, 1952, 1956 and 1969.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
