The History of Flags: From Ancient Symbols to Modern-Day Banners

The history of flags begins more than 5,000 years ago, when ancient Egyptians mounted carved symbols on poles to mark their rulers and gods. The oldest surviving flag, the bronze Shahdad Standard from Iran, is about 4,400 years old. Cloth flags came later, spread by silk from China and the banners of Rome’s legions.

Flags are one of the oldest forms of human communication. Long before written language was widespread, people used standards, banners, and painted symbols to identify their group, rally their forces, and declare what they stood for. The reasons people fly flags today are not so different from the reasons they first appeared.

As a veteran-owned flag and flagpole company, FlagCo sees that connection every day. The flags we manufacture and sell carry the same weight they always have: identity, pride, and purpose. We wrote this guide to answer the questions people actually ask about flag history, including plenty of students working on school reports. You are welcome here.

Why were flags invented?

Flags were invented for identification and communication. On a crowded battlefield or in a royal procession, people needed a way to answer one question from far away: who is that? A symbol raised high on a pole could be seen over the heads of thousands, long before radios, uniforms, or printed signs existed.

The earliest flags were not fabric at all. Ancient Egyptians mounted carved emblems on long poles to mark the presence of a ruler or a god. Carvings from before 3000 BC, including the famous Narmer Palette, already show these standards leading processions. Each district of ancient Egypt had its own standard, the way states and counties have their own flags today.

The common thread across every early example is the same: flags existed because people needed to say “this is who we are” in a way that could be seen from a distance. That job has never changed.

What is the oldest flag in the world?

The oldest flag ever found is the Shahdad Standard, a square metal standard made of bronze around 2400 BC. Archaeologists discovered it in Shahdad, in the Kerman province of present-day Iran, and it is kept at the National Museum of Iran. That makes the oldest known flag roughly 4,400 years old.

The Shahdad Standard survived because it is metal. It shows a seated figure, a kneeling worshipper, animals, and a bird of prey perched on top of the pole. Cloth flags from the ancient world almost never survive; fabric rots, burns, and frays, so most of what we know about early flags comes from carvings, coins, and paintings instead of the flags themselves.

The oldest national flag still in use belongs to Denmark. The Dannebrog, a white cross on a red field, is documented in use by Danish kings since the 1300s and holds the Guinness World Record as the oldest continuously used national flag on Earth.

How did cloth flags spread around the world?

Cloth flags became practical when silk did. Silk is light enough to lift in a breeze, strong enough to survive a campaign, and bright enough to read at a distance. Chinese armies were flying silk banners roughly 3,000 years ago, and the idea traveled west along trade and invasion routes.

The Roman legions refined the concept with the vexillum, a rectangular cloth banner hung from a crossbar on a pole. Each legion carried its own vexillum with distinct markings, which made it possible to coordinate thousands of soldiers across a chaotic battlefield. The study of flags is called vexillology in honor of that Roman banner, a term coined by the American flag scholar Whitney Smith in the late 1950s.

In Persia, the Sasanian Empire displayed ornate royal banners that influenced flag traditions across the Middle East for centuries. By the time of the medieval world, the cloth flag was standard equipment for any army, navy, or ruler from Japan to Western Europe.

How did knights and kingdoms use flags in the Middle Ages?

Medieval armies used flags to tell friend from enemy. Flag design became far more complex with the rise of heraldry: knights and noble families developed unique coats of arms displayed on shields, armor, and banners. On a battlefield where everyone wore similar armor, heraldic flags were the only reliable way to know who was who.

Battle standards became symbols of morale and honor. During the Hundred Years’ War, English and French armies rallied around their flags as expressions of national identity. Losing your standard in battle was considered a serious disgrace, sometimes worse than losing the battle itself. Notable standards from this period include the Lion Rampant of Scotland and the banners of the Teutonic Knights. These were not decorations; they were central to military organization and national pride.

The most famous flag story of the era belongs to Denmark. According to legend, the Dannebrog fell from the sky during the Battle of Lindanise in Estonia on June 15, 1219, turning the tide for the Danish king Valdemar II. Historians treat the story as legend rather than fact, but the flag itself is real and still flying, which is more than 800 years of service either way.

When did countries start using flags?

Countries began adopting national flags in the 1500s and 1600s, as feudal kingdoms gave way to centralized nations. Flags shifted from representing families to representing entire countries, which was a major turning point in the history of flags.

The Netherlands was among the first nations to adopt a horizontal striped flag; its original orange stripe later became red. Great Britain’s first Union Flag appeared in 1606, combining the crosses of England and Scotland after the two crowns were united. The French tricolor, born in the French Revolution, became one of the most influential designs in history and directly inspired dozens of other national flags with its simple three-color format.

Here is the full arc in one table:

What is the history of the American flag?

The American flag was created on June 14, 1777, when the Continental Congress passed the Flag Resolution: “Resolved, That the flag of the United States be thirteen stripes, alternate red and white; that the union be thirteen stars, white in a blue field, representing a new constellation.” June 14 is still celebrated as Flag Day.

Two honest notes that surprise a lot of students. First, nobody knows for certain who sewed the first flag. The Betsy Ross story was first told publicly in 1870, nearly a century later, by her grandson, and historians have never found period evidence for it. The only person who claimed credit at the time was Francis Hopkinson, a signer of the Declaration of Independence, who billed Congress for his flag design work and asked to be paid with “a quarter cask of the public wine.” Congress declined to pay. Whoever sewed it first, the 13-star circle design is still in production today; FlagCo makes a nylon 13-star Betsy Ross flag nearly 250 years later.

Second, the flag has changed more than most people realize. There have been 27 official versions, adding stars as states joined the Union. The current 50-star layout was designed in 1958 by Robert Heft, a 17-year-old Ohio high school student, as a class project. As the story goes, his teacher gave the design a B minus, then raised it to an A after Congress selected it. The 50-star flag became official on July 4, 1960 and is now the longest-serving version of the American flag.

The giant flag that inspired the national anthem in 1814, the Star-Spangled Banner, was sewn in Baltimore by Mary Pickersgill from wool bunting with cotton stars. It survives today at the Smithsonian’s National Museum of American History.

How have flag materials changed?

For most of history, flags were made from wool, linen, or silk. Those materials looked impressive but deteriorated quickly outdoors, especially in rain and direct sunlight. Battlefield flags often lasted only a few engagements before needing replacement.

The development of synthetic fabrics in the 20th century changed everything. As a company that sells flags every day, this is the part of flag history we live in.

What do flags symbolize today?

Flags still represent identity, values, and belonging, exactly what they represented 3,000 years ago. What has changed is the range of identities they represent.

National flags remain the most prominent, and their designs carry specific meaning. The red, white, and blue of the American flag are usually explained as valor, purity, and justice. Here is the detail most websites skip: the 1777 Flag Resolution assigned no meanings at all. The familiar definitions come from Charles Thomson’s 1782 description of the Great Seal of the United States, where red stands for hardiness and valor, white for purity and innocence, and blue for vigilance, perseverance, and justice. The meanings attached to the flag afterward.

Military flags hold particular significance. Service branch flags, POW/MIA flags, and memorial drapes honor those who served and sacrificed. For veterans and military families, these flags are deeply personal symbols.

Flags have also become tools for social and cultural expression. Pride and heritage flags represent communities and movements, continuing the ancient tradition of using flags to say “this is who we are.”

How do you display a flag respectfully?

The U.S. Flag Code, Title 4 of the United States Code, sets the rules for displaying the American flag with respect. The flag should be flown from sunrise to sunset unless it is properly illuminated at night. It should never touch the ground, and a worn or faded flag should be retired respectfully, typically through a ceremonial burning, often handled free of charge by groups like the American Legion or the Scouts.

The Flag Code became federal law in 1942, but its rules were first agreed at a National Flag Conference in 1923. The “illuminated at night” rule is why public buildings light their flags after dark; purpose-built flagpole lighting exists almost entirely because of that one sentence.

Sizing the flag to the pole matters too. The general rule is that the flag’s length should be about one quarter of the pole’s height above ground. These are the standard pairings we use as a manufacturer, and they hold for any flagpole in these height ranges, whatever the brand:

If you are choosing a pole rather than a flag, our guide to choosing the right flagpole height walks through the same logic from the other direction.

Fast flag facts for students

Quick, verified facts that tend to win trivia nights and improve school reports:

• Nepal has the only non-rectangular national flag in the world: two stacked triangles called a double pennant.
• Switzerland and Vatican City are the only countries with square national flags.
• Ohio has the only non-rectangular US state flag, a swallowtail shape called a burgee.
• The flags planted on the Moon by the Apollo missions were ordinary nylon flags. Six were planted between 1969 and 1972.
• A person who studies flags is a vexillologist, from the Latin vexillum, the Roman military banner.
• The 50-star American flag is the only version designed, at least in part, by a teenager doing homework. Respect to Robert Heft.

What is the future of flags?

The future of flags looks like better fabrics, smarter lighting, and a surprising wave of brand-new designs. The job of a flag has not changed in 4,400 years, but how flags are made, lit, and flown is changing fast.

New flags are still being designed right now. The United States is in the middle of a genuine redesign era. Mississippi adopted its New Magnolia flag in 2021, retiring a design that had flown since 1894. Utah raised a new beehive flag in 2024, and Minnesota adopted its North Star flag on May 11, 2024. Dozens of cities are rethinking their flags too, often with vexillologists consulting on the designs. Flag design is not a dead art; it is busier than it has been in a century.

Materials and printing keep improving. Modern nylon and polyester already outlast anything in history, and fabric makers keep adding better UV inhibitors so colors hold longer in the sun. Digital dye-sublimation printing now turns a custom design into a finished flag in days instead of weeks, which is why schools, businesses, and towns can afford flags of their own. Flag makers are also experimenting with recycled fabrics.

The hardware is getting smarter. Solar LED flagpole lights can now light a flag after dark with no trenching and no wiring, which satisfies the Flag Code’s illumination rule in places electricity never reached; FlagCo builds its Beacon in both 110V and solar versions today. Motorized and remote-controlled hoisting systems are starting to appear on commercial flagpoles, and lighting designs are getting better at putting light on the flag instead of into the night sky.

Whatever the fabric, the light source, or the design, the future of flags is the same as their past: a symbol raised high enough for everyone to see. A student writing this report in 2050 will be answering the same question people asked in ancient Egypt: who are we, and how do we show it?
