Look at the flags of Jordan and Iraq side by side and you'll swear they belong to different families entirely. Jordan wears a red triangle stabbed into black, white and green stripes. Iraq is a flat red, white and black tricolor with green script running through the middle. Different shapes, different feel, different politics.
Now check their color palettes. Identical. Black, white, green, red. The same four colors, arranged two different ways, tracing back to two separate moments a Middle East torn apart by empire tried to answer the same question: what does an Arab flag look like?
The answer split into two family trees. One grew out of a 1916 revolt against the Ottomans. The other grew out of a 1952 coup against a king. Nearly every Arab flag flying today descends from one branch or the other, and once you know which branch is which, you read the politics of a country off its flagpole.
A poet wrote the palette centuries before anyone needed it
Long before anyone stitched these colors into cloth, a 14th-century poet named Safi al-Din al-Hilli gave them their meaning in a single line of verse: white are our deeds, black our battles, green our fields, red our swords.
That's the whole inheritance. Four colors, each one already carrying a caliphate on its back by the time flag designers got to them centuries later. Black stood for the Rashidun and Abbasid caliphs and their black battle standards. White stood for the Umayyads. Green stood for the Fatimids, and by extension for Islam itself. Red belonged to the Hashemites, the family that traced its lineage to the Prophet Muhammad and would go on to rule Jordan.
Nobody had combined all four into one flag. There was no need to. Then World War One gave the region a reason.
Hussein bin Ali and a British diplomat sketch a flag for a revolt
In 1916, Hussein bin Ali, the Sharif of Mecca, led an uprising against Ottoman rule with British backing. He needed a banner distinct from the Ottoman flag and, pointedly, from the French tricolor flying over French-controlled Arab territory nearby. A British diplomat named Mark Sykes, yes, that Sykes, half of the Sykes-Picot line that would later carve up the region, drew up several options. Hussein picked one.
The result combined all four pan-Arab colors for the first time: a red triangle at the hoist, with black, green and white stripes running horizontally behind it. Adopted on 10 June 1916, it became known as the Flag of the Arab Revolt, or the Flag of Hejaz. Arab forces raised it over Aqaba after capturing the port in July 1917.
Hussein's revolt aimed for a single unified Arab kingdom spanning what's now Syria, Lebanon, Israel, the Palestinian territories and Jordan. That kingdom never happened. The flag outlived the dream anyway.
Jordan carries the clearest bloodline back to Hejaz. Between 1921 and 1928, the emerging Emirate of Transjordan flew the same black-white-green stripes and red triangle, no additions. In 1928, a seven-pointed white star landed inside the triangle, one point for each verse of the Quran's opening chapter, and for the unity of the Arab peoples more broadly. That's the flag Jordan still flies, officially fixed on 16 April 1928.
The triangle spreads, and the meaning drifts
Once one nation had proven the design worked, the triangle-and-stripes layout became a template. Each country that adopted it kept the shape and quietly rewrote what the colors meant, trading medieval dynasties for whatever their founding moment called for.
The Palestine Liberation Organization adopted the black-white-green-and-red-triangle flag on 28 May 1964, the year of its founding. It wasn't a fresh design. The same pattern had already flown during the 1936 to 1939 Arab revolt in Mandatory Palestine, a direct visual claim to Hussein's unfinished project and to the borders his revolt had once imagined.
Kuwait's story runs differently. Before independence, Kuwait flew a plain red flag, like most Gulf sheikhdoms of the era. Independence in 1961 called for something that said more. The new flag, adopted on 7 September and hoisted on 24 November that year, kept Hejaz's triangle and stripes but handed the colors a civic reading built for a young state: green for the land, white for peace, red for the blood of those who defended it, black for the battles behind them. Same palette, same shape, a completely different story attached to it.
The UAE's version has the best origin story of the four. In 1971, as the emirates prepared to unite, a nationwide competition drew over a thousand flag submissions. A 19-year-old named Abdullah Mohammed Al Maainah won. He didn't find out until the flag was already flying over the palace in Abu Dhabi, because the newspaper photos of the finalist designs had run in black and white and he couldn't tell which one was his. He ran to the palace fence and stood on his toes to check the colors himself. Adopted on 2 December 1971, the flag now carries symbolism built for a federation of oil states: black for oil, green for fertility, red and white tying the emirates together.
Four countries, one triangle, four completely different explanations for what the same four colors are supposed to mean.
1952 splits off a second family
While the Hejaz line was spreading east across the Gulf, a second lineage was forming in Cairo, and it wanted nothing to do with dynasties or triangles.
On 23 July 1952, Egypt's Free Officers, led by Muhammad Naguib and Gamal Abdel Nasser, toppled King Farouk. Nasser's new republic needed a flag that broke visibly from the monarchy, so it dropped the triangle, dropped green from the primary field, and settled on three plain horizontal bands: red, white and black. Officially, it became known as the Arab Liberation Flag.
The reinterpretation was total. Black no longer meant the Abbasid caliphate. It meant colonial oppression, the era Nasser's revolution claimed to be ending. White stopped being about the Umayyads and became a bright, secular future. Red kept a version of its old meaning, sacrifice, but now for liberation struggles rather than Hashemite honor. This wasn't a flag about medieval succession. It was a flag about socialism, republicanism and throwing off empire, and Nasser's brand of pan-Arabism carried it well beyond Egypt's own borders.
Where the Liberation flag landed
The Liberation Flag's plain stripes turned out to be as adaptable as Hejaz's triangle. Syria adopted a version during its short-lived union with Egypt as the United Arab Republic in 1958. Libya flew a version too, before dropping it in 1977. Both eventually moved on, but the design's biggest and most lasting home turned out to be Iraq.
Iraq adopted the red-white-black tricolor under Ba'athist rule in 1963, originally with three green stars representing the party's motto of unity, freedom and socialism. Those stars became politically radioactive. Kurdish communities associated them with the Anfal campaign carried out under Saddam Hussein, so when Iraq redesigned its flag in 2008, the stars came out entirely. What replaced them was the takbir, the phrase "God is greatest," rendered in green Kufic script across the center stripe. The script had originally run in Saddam's own handwriting, before being swapped for the more neutral Kufic style in 2004 and then formalized in the 2008 flag. Same three colors as 1963. A flag actively trying to shed its old associations while keeping the palette everyone recognized.
Sudan shows what happens when a country decides it doesn't want to choose sides between the two families. After a 1969 coup, Sudan held its own design competition, won by artist Abdel Rahman Ahmed Al-Jali. Adopted on 20 May 1970, the result takes the Liberation Flag's red-white-black horizontal bands and grafts on a green triangle at the hoist, structurally closer to Hejaz's layout than to Nasser's flat stripes. It's a genuine hybrid: one lineage's colors and general logic, the other's shape. Black, fittingly, also does double duty in Sudan's flag, since "Sudan" itself derives from the Arabic word for black, alongside the usual reference to the Mahdist resistance that once fought British and Egyptian rule from the same region.
Syria proves the rule by breaking it
Syria's own 1930 independence flag was neither Hejaz's triangle nor Nasser's Liberation stripes. It was its own green-white-black tricolor with three red stars on the white band, each star originally standing for a historical region of the country. When Syria merged with Egypt in 1958, Nasser's government swapped in the red-white-black Liberation Flag with two green stars for the union. Syria kept variations on that Liberation-line design, through a Ba'athist three-star version and later the red-white-black flag with the Hawk of Quraish emblem, all the way until December 2024.
When the Assad government fell that month, the flag that replaced it within days wasn't a new design at all. It was Syria's own 1930 tricolor, green, white and black with three red stars, formally written into the country's 2025 constitutional declaration. Syria didn't join either family tree on its way out. It skipped both and went home to the flag it had before Nasser ever got involved, proof that the four-color palette was always bigger than the two lineages built on top of it.
The colors survive. The stories keep getting rewritten
What makes this palette striking isn't that it spread. Plenty of color schemes spread. It's that every single country that adopted it, whether by inheriting Hejaz's triangle or Nasser's stripes or neither, felt obligated to write its own explanation for what the colors meant. Kuwait didn't borrow Jordan's shape and call it done. It rebuilt the symbolism from scratch, land and peace and sacrifice, because a flag copied without a new story attached feels like someone else's flag.
That's the real inheritance from al-Hilli's poem. Not the specific dynasties he named, most of which mean little to a young Emirati or a Sudanese voter today, but the idea that a handful of colors carry a nation's entire self-image if a country is willing to keep rewriting what they stand for. Seven centuries after a poet wrote about swords and battlefields, his four colors are still doing exactly what he described: representing acts, battles, fields and swords, under completely different names.
