Medieval Armor

Overview

Medieval armor in Europe during the High Medieval period (roughly the 11th to 13th centuries) consisted primarily of chain mail, a type of armor made from interlocking metal rings. It provided flexible protection against cuts and thrusts from swords and spears. A padded garment called a gambeson was worn underneath to absorb shock. Over the head, a conical or rounded helm of iron or steel offered defense for the skull and face. Plate armor, made from solid metal plates, began to appear in limited forms such as knee and shin guards, but full suits of plate did not become common until the later Middle Ages. Armor was expensive and typically owned by nobles and professional soldiers. The development of armor was closely tied to changes in weapons and tactics, including the rise of the crossbow and the longbow, which could pierce mail at certain ranges. Armor was not just protective gear; it also signaled social status and was often decorated. By the end of the High Medieval period, improvements in metallurgy and the need for better protection led to more plate elements being added to the knight's equipment.

Armor was not worn all the time; it was put on for battle, tournaments, or guard duty. A knight might have a squire to help with the many straps and buckles. The weight of chain mail was distributed over the body, but it could still be tiring to wear for long periods. Helmets restricted vision and hearing, which could be dangerous in a melee. Despite these drawbacks, armor was essential for survival in combat. The High Medieval period saw a gradual evolution from mostly mail to a mix of mail and plate, setting the stage for the full plate armor of the 14th and 15th centuries. This evolution was driven by the constant arms race between offense and defense.

Historical background

The High Medieval period in Europe, spanning approximately the 11th to 13th centuries, was a time of significant political and military change. After the collapse of the Carolingian Empire, local lords gained power, leading to the rise of feudalism. Knights, mounted warriors who served lords in exchange for land, became central to warfare. Early medieval armor had been simple, often just a helmet and a leather or cloth cuirass. By the 11th century, chain mail had become the dominant form of body armor for those who could afford it. The Bayeux Tapestry, which depicts the Norman Conquest of 1066, shows soldiers wearing knee-length mail shirts called hauberks and conical helmets with nose guards. This visual evidence, though not a photograph, is one of our best sources for armor of that time.

During the 12th and 13th centuries, armor continued to develop. The Crusades brought European knights into contact with Byzantine and Islamic armor, which sometimes included lamellar and scale designs. However, mail remained the standard in Europe. Helmets evolved from simple conical shapes to enclosed helms that covered the entire head, such as the great helm, which appeared in the 12th century. Great helms offered better protection but limited vision. Underneath mail, knights wore a padded coif and a gambeson. By the late 13th century, plate armor began to supplement mail, first as small plates on the knees, elbows, and shoulders. The introduction of the longbow and crossbow, which could penetrate mail, encouraged the addition of more plate. The High Medieval period thus laid the groundwork for the later dominance of plate armor.

How it worked

Chain mail was made by linking iron or steel rings together in a pattern. Each ring was typically riveted shut to prevent it from opening during combat. The resulting garment, called a hauberk, covered the torso, arms, and sometimes the legs. Mail was effective because it could absorb the energy of a cutting blow by flexing, and the rings were hard enough to resist penetration by a sharp point. However, mail could be heavy, weighing around 10 to 15 kilograms for a full hauberk. The weight was borne on the shoulders and hips, and a belt helped distribute it. Under the mail, a padded gambeson of linen or wool provided cushioning and prevented the rings from chafing the skin. Over the mail, a surcoat of cloth was often worn to protect the metal from rain and to display heraldry.

Helmets were crucial for protecting the head. Early helms were conical and covered the top of the skull, with a nasal bar to protect the nose. By the 12th century, the great helm enclosed the entire head and had narrow slits for vision and breathing. It was heavy and hot, and it restricted the wearer's senses, but it offered superior protection. Plate armor, when it appeared, was made from large metal plates shaped to fit the body. These plates were attached to each other with hinges and straps, allowing some movement. Plate was more effective than mail against blunt force and piercing weapons, but it was also more expensive and required skilled craftsmen to make. In the High Medieval period, plate was usually limited to small pieces like knee cops and shoulder guards, worn over mail. The combination of mail and plate provided a balance of flexibility and protection.

Daily life and society

Armor was a significant investment and a marker of social class. A full suit of chain mail could cost as much as a small farm, so only the wealthy could afford it. Knights, who were minor nobles, were expected to own armor and weapons as part of their feudal obligations. They trained from a young age in the use of arms and the wearing of armor. Squires, young men training to become knights, assisted knights in putting on and maintaining their armor. Armor required regular care: mail was cleaned by rolling it in a barrel with sand and vinegar to remove rust, and leather straps were oiled to keep them supple. A knight's armor was often passed down or given as a reward for service.

For common soldiers, armor was much simpler. Many wore padded gambesons or leather jerkins, and simple iron helmets. They could not afford mail. In times of war, lords might equip their retainers with basic armor from their armories. Armor also played a role in tournaments, which were both military training and social events. Knights competed in mock battles and jousts, wearing specialized armor that was often more decorative than practical. The church sometimes tried to limit tournaments because of the violence and the risk of death, but they remained popular. In daily life, knights did not wear armor all the time; they wore normal clothing when not on duty. Armor was stored in armories or chests and was put on only when needed. The maintenance and production of armor supported a class of craftsmen, such as mail makers and later plate armorers, who worked in towns and castles.

Key developments and legacy

The High Medieval period saw several key developments in armor. One was the gradual improvement of mail, with denser weaves and better riveting. Another was the introduction of the great helm, which provided full head protection. The most significant development was the beginning of plate armor. Initially, plates were added to protect vulnerable areas like the knees, shins, and elbows. By the late 13th century, plates were also used for the torso, in the form of a coat of plates, which was a garment with metal plates riveted inside. This was a precursor to the full breastplate. These developments were driven by the need to counter better weapons, such as the crossbow and the longbow, which could pierce mail. The longbow, in particular, was used effectively by the English in the 14th century, but its rise began in the High Medieval period.

The legacy of High Medieval armor is evident in the later full plate armor of the 15th century, which represented the pinnacle of personal armor. It also influenced the design of modern protective gear, such as bulletproof vests, which use similar principles of energy absorption. Armor from this period is displayed in museums around the world and is a popular subject in historical reenactment and fantasy. The image of the knight in shining armor is a cultural icon, though it often conflates different periods. The High Medieval period is crucial for understanding how armor evolved from simple mail to complex plate. It also shows how technology and society interacted: armor was both a product of and a driver of social hierarchy and military tactics.

Common misconceptions

One common misconception is that medieval armor was extremely heavy and made movement impossible. In reality, a full suit of chain mail weighed about 10 to 15 kilograms, and later plate armor weighed around 20 to 25 kilograms, which is less than a modern soldier's backpack. The weight was distributed over the body, and knights could run, jump, and even climb ladders in armor. Another misconception is that armor was always worn. In fact, it was put on for battle or tournaments and taken off otherwise. Knights did not wear armor to dinner or to bed. A third misconception is that plate armor was common in the High Medieval period. Full plate armor did not appear until the 14th and 15th centuries; in the High Medieval period, mail was the primary armor, with plate used only in small pieces.

Another misconception is that armor made knights invulnerable. While armor provided good protection, it could be penetrated by powerful crossbows, longbows, or specialized weapons like war hammers and poleaxes. Blunt force could also cause injury even if the armor was not pierced. Additionally, armor had gaps at the joints and visor, which could be targeted. A final misconception is that armor was only for knights. In reality, common soldiers wore simpler armor such as gambesons and helmets, and even knights started as squires wearing lighter armor. Armor was also used by other cultures, but this article focuses on Europe. Understanding these misconceptions helps to appreciate the real capabilities and limitations of medieval armor.

Frequently asked questions

Q: How much did medieval armor cost? A: The cost varied widely. A full suit of chain mail in the High Medieval period could cost as much as a small farm or a herd of cattle. A simple helmet might cost less, but still represented a significant sum for a common soldier. Because of the expense, armor was often inherited or provided by a lord to his retainers. Exact prices are difficult to state because they changed over time and place, and surviving records are limited.

Q: Did knights really need help to get on their horses? A: No, that is a myth. Knights were trained to mount and dismount in armor. While a squire might assist with putting on armor, once dressed, a knight could move freely. The weight of armor was distributed, and the saddle had a high pommel and cantle for support. However, in full plate armor of later periods, mounting could be more difficult, but even then, knights could do it alone if necessary.

Q: Was armor hot to wear? A: Yes, armor could be very hot, especially in summer. The metal absorbed heat, and the padding underneath added insulation. Knights could suffer from heat exhaustion. To mitigate this, they might wear lighter clothing underneath and drink water when possible. In tournaments, they sometimes wore specialized armor with better ventilation. But overall, wearing armor for long periods was uncomfortable, and it was one reason why battles were often fought in cooler months or in the morning.
