Flag of Sudan

Design and symbolism

The design is a horizontal red (red), white (white) and black (black) tricolour with a green (green) isosceles triangle at the hoist. This arrangement is usually referred to as a tricolour with a hoist wedge rather than a simple three-band flag. Interpretations of the colours vary: red frequently evokes the struggle and sacrifices associated with Sudan’s political history, white suggests peace and optimism, black is associated with Sudan itself and historic identity, and green traditionally relates to Islam, agriculture and fertility of the land. Official statements and popular accounts may emphasize different aspects of these meanings.

History and influences

The 1970 flag draws on the Arab Liberation flag tradition and the wider set of Pan-Arab colours that influenced several mid-20th century national flags. Its palette and composition echo patterns used in the region, notably in countries such as Egypt, Iraq, Syria and Yemen. The 1970 adoption followed political changes that prompted a replacement of the earlier 1956–1970 national flag, which had a different set of colours and reflected the immediate post-independence era.

Proportions, variants and protocol

Standard references and vexillological sources provide specifications for proportions and colour shades; national and military services use variants such as state standards, naval ensigns and unit flags. Flag protocol in Sudan aligns with common international practice: the flag is flown on national holidays, used in diplomatic settings, and may be lowered to half-mast in times of national mourning. Proper display, maintenance and respect for the flag are stressed in official guidance.

Comparisons and notable features

• The green triangle at the hoist distinguishes Sudan’s banner from other red-white-black tricolours and creates a characteristic silhouette when flown.
• As part of the Pan-Arab family of flags, Sudan’s design is often examined in comparative studies of national symbols across North Africa and the Middle East.
• Historical changes in Sudan’s flags reflect shifts in political regimes and national identity since independence from Anglo-Egyptian rule.
