Shield

• 1. Introduction

  ›

  A shield, at its most basic, is a piece of personal armour held in the hand, and for thousands of years it stood between a soldier and death. From the wicker frames of Mycenaean Greece to the polycarbonate riot shields carried by police units today, this single object has tracked the full arc of human conflict. What made the shield so durable? Why did some armies abandon it entirely, while others clung to it long after firearms made it seem obsolete? And how did a battlefield tool become a symbol of authority, identity, and ceremony across cultures from Cameroon to Borneo? Those questions run through the whole story.

• 2. Ancient Origins

  ›

  The first prototype of the shield is believed to have appeared in the Late Neolithic Age, though the oldest surviving examples date to the Bronze Age. Wood and animal hide were far more common construction materials than metal; wicker and even turtle shells also appear in the record. Metal shields that do survive from those early periods, such as the Yetholm-type shields of the Bronze Age and the Iron Age Battersea shield, are generally thought to have been ceremonial rather than practical.

  The Sards, also called the Shardana, serve as one of the earliest precisely dated examples of shields in action. Working as mercenaries for the Egyptian pharaoh Ramses II during the 14th-13th century BC, they carried either large or small round shields against the Hittites. Further west, the Mycenaean Greeks had already developed two distinct forms: the figure-of-eight shield and a rectangular tower shield, both built on wicker frames reinforced with leather and large enough to cover a warrior from head to foot.

  The Ancient Greek hoplites favoured something quite different, a round bowl-shaped wooden shield reinforced with bronze called an aspis. The aspis became the foundation of the Greek phalanx formation used by the Spartans, where each soldier's shield protected not only himself but the comrade to his left. Heavily armored Roman legionaries carried their own version, the scutum, which began as oval during the early republican era before gradually taking on the rectangular shape associated with the early Imperial legions. The Romans deployed their scuta in the testudo, a tortoise-like formation that enclosed large groups of soldiers in an armoured box to protect them from missiles and allow advances under heavy fire.

  Germanic wooden shields from roughly 350 BC to 500 AD survive because they were deposited in Danish bogs as weapons sacrifices, preserving details that would otherwise have rotted away entirely.

• 3. Medieval Transformations

  ›

  Round shields dominated the early European Middle Ages, typically built from light, non-splitting wood such as linden, fir, alder, or poplar. A leather cover on one or both sides reinforced them, and a metal boss sat at the center. That boss was not merely structural. Fighters of the period used it to deflect incoming blows and, when the moment called for it, to punch the opponent directly.

  The Normans changed the equation around the 10th century when they introduced the kite shield, rounded at the top and tapered toward the bottom. The kite shape was particularly suited to horsemen, whose legs would otherwise be left exposed, and it was gripped tight to the arm by leather straps called enarmes. It gradually displaced the round shield as the standard choice until the end of the 12th century, when improvements in limb armour allowed shields to shrink. By the 14th century the kite shield had been replaced entirely.

  The successor was the heater shield, smaller than the kite, shaped from several layers of laminated wood with a gentle curve in cross section. That heater shape is the origin of the symbolic heraldic shield still used today. As the heater style evolved, specialists added functional modifications: the bouche had a lance rest cut into its upper corner to guide the weapon in combat or tournament. Crossbowmen who needed cover while reloading stood behind free-standing shields called pavises, propped up on stands at a safe distance from the fighting.

  Some armoured foot knights eventually gave up shields altogether in favour of two-handed weapons and greater mobility. Those who kept a shield often switched to the buckler, a small round shield typically between 8 and 16 inches, or 20 to 40 centimeters, in diameter. The buckler was one of the very few shield types usually made of metal rather than wood. Light enough to hang from a belt, it offered almost no protection against missiles but was well suited for hand-to-hand combat, where it served for both defence and offence. The buckler's use ran from the Middle Ages well into the 16th century, and its reputation survives in the word swashbuckler.

• 4. Africa's Shield Traditions

  ›

  Zulu warriors carried a shield called the Ishlangu, made from a single ox hide supported by a wooden spine, and it was especially long and broad, often covering much of the warrior's body. The Ishlangu was used alongside a short spear called the iklwa and sometimes a club. Zulu shields were still in active military use as late as the 19th century, even as industrialised armies had long moved on to firearms.

  Across southern Africa the variety was striking. Nguni shields were generally oval; the Tswana, from present-day Botswana and northwestern South Africa, used hourglass-shaped shields; the Pedi of Limpopo preferred apron-shaped designs; and Sotho shields were smaller, suited to the highland regions of Lesotho and nearby areas. Other traditions extended well beyond the continent's southern zone. The Glagwa came from Cameroon, the Nguba from Congo.

  The Igbo people of southeastern Nigeria crafted their shields from woven palm stems. According to M. D. W. Jeffreys, writing in his study on Ibo Warfare, Igbo fighters used two main types. Heavy wooden shields protected villages but were too impractical to carry in raids. Lighter wicker shields were portable enough for active combat and battle situations. In the 18th and 19th centuries, Igbo warriors also wielded bows, arrows, swords, javelins, and firearms alongside those shields.

  Nguni warriors struck their shields to create rhythmic beats during warfare and ritual, with hand claps and ankle rattles adding to the intensity. That dual function, practical weapon and cultural object, runs through African shield traditions broadly. What once served as battlefield protection has become primarily ceremonial and artistic, representing authority, cultural identity, and heritage.

• 5. Southeast Asian Forms

  ›

  Malay and maritime peoples across the region used a circular shield called a taming, woven tightly from rattan or cut from wood, well suited to sword and spear combat in Malaysia and Indonesia. Tribal groups in the Philippines, including the Moro, Lumad, and Visayan peoples, also favoured the taming.

  In the southern Philippine islands, Moro communities produced round, oblong, and rectangular shields. Their round shields are associated with Islamic influences rather than Malaysian ones, and most were cut from solid wood and strengthened with rattan edging. Further east, Austronesian ethnic groups in Indonesia and Malaysia, including Dayak peoples of Borneo such as the Kenyah, Kayan, Ot Danum, and Ngaju, used large wooden body shields that were often hexagonal. Those shields were known by the names keliau, kelibit, or telawang depending on the group.

  The lighter roromaraugi and the qauata represent a specific design philosophy at the opposite end of the spectrum from the heavy war shield. These thinner, lighter shields were designed mainly for deflecting blade strikes rather than absorbing the impact of heavy projectiles, reflecting the different threats their users expected to face.

• 6. Heraldry and Identity

  ›

  Painted patterns and animal representations on shields signalled army or clan affiliation long before heraldry became a formal system. Aristocratic officials, knights, barons, dukes, and kings, had their shields painted with customary designs known as a coat of arms. During the High Middle Ages, these designs were systematised into heraldic devices used specifically for battlefield identification, a practical response to the problem of recognising combatants whose faces were concealed by helmets.

  The heater shield's shape became so closely associated with that heraldic tradition that it endures as the standard symbolic form of the shield to this day. In heraldry, the shield remains the central element of a coat of arms, carrying the main design and focus of the arms itself. That symbolic weight outlasted the shield's military usefulness by centuries, which is why the form appears on everything from national emblems to sports club badges long after no soldier has carried one into battle.

• 7. Modern Shields

  ›

  Scottish Highland fighters were still wielding small round shields called targes in the 18th century, using them against British infantry bayonets and cavalry swords in close fighting. Their targes offered only partial effectiveness against the firearms of the period, but in close-in combat they remained relevant. That persistence points to a broader pattern: shields survived in military use not because they defeated the most advanced weapons of any given era, but because some combat situations still called for them.

  Today, police and military units that specialise in riot control, hostage rescue, antiterrorism, and siege-breaking carry two main categories of modern shield. Riot shields are made from metal or polymers such as polycarbonate Lexan, Makrolon, or boPET Mylar. Synthetic versions are normally transparent so officers can see without obstruction; metal versions have a small window at eye level for the same reason. These shields protect against rocks, bottles, fists, clubs, and molotov cocktails, and are commonly used in a wall formation to block and push back crowds.

  The second category is the ballistic shield, also called a tactical shield, manufactured from advanced synthetics such as Kevlar and designed to stop pistol cartridges at the lighter Level IIIA rating, or rifle cartridges at the heavier Level III and IV ratings. Tactical shields typically include a firing port so the officer holding the shield can use a weapon while remaining protected, along with a bulletproof glass viewing port. SWAT teams deploy them in high-risk entry scenarios, hostage rescues, and breaching operations. Many law enforcement shields carry large text reading "POLICE" or the name of the specific force, such as "US MARSHALS", so bystanders can identify the bearer at a glance.
