Plate armour is a historical type of personal armour made from iron or steel plates.

While there are early predecessors such the Roman-era lorica segmentata, full plate armour developed in Europe during the Late Middle Ages, especially in the context of the Hundred Years' War, from the coat of plates worn over mail suits during the 13th century. In Europe plate armour reached its peak in the late 15th and 16th centuries, with the full suits of Gothic plate armour worn on the battlefields of the Burgundian and Italian Wars. The most heavily armoured troops of the period were heavy cavalry such as the gendarmes and early cuirassiers, but the infantry troops of the Swiss mercenaries and the landsknechts also took to wearing lighter suits of "three quarters" plate armour, leaving the lower legs unprotected.

The use of plate armour in Europe declined in the 17th century, but remained common both among the nobility and for the cuirassiers throughout the European wars of religion. After 1650, plate armour was mostly reduced to the simple breastplate (cuirass) worn by dragoons. This was due to the development of the flintlock musket which could penetrate armour at a considerable distance, severely reducing the payoff from the investment in full plate armour. For infantry, the breastplate gained renewed importance with the development of shrapnel in the late 18th century. The use of steel plates sown into flak jacket dates to World War II, replaced by more modern materials such as fibre-reinforced plastic since the 1950s.

Ancient history

Partial plate armour, which protected the chest and the lower limbs, was used by the ancient Greeks and Romans, but it fell into disuse after the collapse of the Roman Empire because of the cost and work involved in producing a piece of metal plate or cuirass. Single plates of metal armour were again used from the late 13th century on, to protect joints and shins, and these were worn over a mail hauberk.

Late Middle Ages Europe

By the end of the 14th century, larger and complete full plates of armour had been developed. During the early 16th century the helmet and neckguard design was reformed to produce the so-called Nürnberg armour, many of them masterpieces of workmanship and design.

European leaders in armouring techniques were northern Italians and southern Germans. This led to the styles of ''Milanese'' from Milan, and ''Gothic'' from the Holy Roman Empire. England produced armour in ''Greenwich'' and they both developed their own unique style. Ottoman Turkey also made wide use of plate armour but incorporated large amounts of mail into their armour, which was widely used by shock troops such as the Janissary Corps.

Renaissance Europe

Renaissance-era Maximilian armour was typically denoted by fluting and decorative etching, as opposed to the plainer finish on 15th-century white armour. This era also saw the use of closed helms, as opposed to the 15th-century-style sallets and barbutes.

A Renaissance-era full suit of plate armour would have consisted of a helmet, a gorget (or bevor), pauldrons (or spaulders), couters, vambraces, gauntlets, a cuirass (back and breastplate) with a fauld, tassets and a culet, a mail skirt, cuisses, poleyns, greaves, and sabatons. A complete suit of plate armour made from well-tempered steel would weigh around 20 kg (45 pounds). The wearer of such a suit remains highly agile, able to move freely, jump and run, the weight being well spread over the body.

Reduced plate armour, typically consisting of a breastplate, a burgonet, morion or cabasset and gauntlets, however, also became popular among 16th-century mercenaries and there are many references to so-called munition armour being ordered for infantrymen at a fraction of the cost of full plate armour. This mass-produced armour was often heavier and made of lower quality metal than knight armour.

Specialized jousting armour produced in the late 15th to 16th century was heavier, and could weigh as much as , as it was not intended for free combat, it did not need to permit free movement, the only limiting factor being the maximum weight that could be carried by a warhorse of the period.

The medieval joust has its origins in the military tactics of heavy cavalry during the High Middle Ages. These became obsolete during the 14th century, and since the 15th centry, jousting had become a sport (''hastilude'') without direct relevance to warfare. During the 1490s, emperor Maximilian I invested a lot of effort into perfecting the sport, for which he received his nickname of "The Last Knight". ''Rennen'' and ''Stechen'' were two sportive forms of the joust developed during the 15th century and practised throughout the 16th century. The armours used for these two respective styles of the joust was known as ''Rennzeug'' and ''Stechzeug'', respectively. The ''Stechzeug'' in particular developed into extremely heavy armour which completely inhibited the movement of the rider, in its latest forms resembling an armour-shaped cabin integrated into the horse armour more than a functional suit of armour. Such forms of sportive equipment during the final phase of the joust in 16th-century Germany gave rise to modern misconceptions about the heaviness or clumsiness of "medieval armour", as notably popularized by Mark Twain's ''A Connecticut Yankee in King Arthur's Court''. The ''Stechzeug'' featured extremely heavy helmets because the aim was to detach the crest of the opponent's helmet, resulting in frequent full impact of the lance to the head. By contrast the ''Rennen'' was type of joust with lighter contact. Here, the aim was to hit the opponent's shield. The specialized ''Rennzeug'' was developed on the request of Maximilian, who desired a return to a more agile form of joust compared to the heavily armoured "full contact" ''Stechen''. In the ''Rennzeug'', the shield was attached to the armour with a mechanism of springs and would detach itself upon contact.

Early Modern period

Plate armour was widely used by most armies until the end of the 17th century for both foot and mounted troops such as the cuirassiers, dragoons, demi-lancers and Polish hussars.

The infantry armour of the 16th century developed into the ''Savoyard'' type of three-quarters armour by 1600.

Full plate armour was expensive to produce and remained therefore restricted to the upper strata of society; lavishly decorated suits of armour remained the fashion with 18th-century nobles and generals long after they had ceased to be militarily useful on the battlefield due to the advent of inexpensive muskets.

Decline in the 18th century

Body armour remained in use throughout the 18th century with cavalry units, especially cuirassiers, including front and back plates that could protect the wearer from distanced fire and either helmets or "secrets", a steel protection they wore under a floppy hat.

Japan

Development of plate armour in Japan mostly occurred in parallel to that of the West.

In Kofun period Japan, during the 4th and 5th centuries, very advanced iron plate cuirasses called ''tanko'' and helmets were made. Plate armour was used in Japan during the Nara period (646-793), both plate and lamellar armours have been found in burial mounds and ''haniwa'' (ancient clay figures) have been found depicting warriors wearing full armour.

In Japan the warfare of the Sengoku period (15th and 16th centuries) required large quantities of armour to be produced for the ever growing armies of foot soldiers (''ashigaru''). Simple munition quality (''okashi'' or lent)chest armours (''dou or dō'') and helmets (''kabuto'') were massed produced.

In 1543, the Portuguese brought matchlock firearms (''tanegashima'') to Japan. The Japanese started to manufacture the Portuguese acquired matchlocks and the use of these firearms in warfare caused the gradual decline in the use of the centuries old ''lamellar armour'' that the samurai were known for; the Japanese armour makers started to use solid iron plates in their armour designs which were based on European armours, and eventually plate armour became the standard for samurai warriors.The new style Japanese plate armours were called ''tosei gusoku'' (new armours) in order to differentiate from the old style ''lamellar'' armours. Japanese armour makers designed bullet proof iron and steel plate armours called ''tameshi gusoku'' or (bullet tested), which allowed them to continue wearing armour despite the heavy use of firearms in the late 1500s.

In the 1600s warfare in Japan came to an end but the samurai continued to use plate armour until the end of the samurai era in the 1860s, with the known last use of samurai armour occurring in 1877 during the satsuma rebellion.

20th century and modern body armour

Body armour made a brief reappearance in the American Civil War with mixed success. However, the armour vests of the time were expensive and thus bought by individual troops and not issued, meaning that the effectiveness of the armour varied widely depending on its maker. Plate armour was successfully implemented by Australian outlaw Ned Kelly and his gang, giving them a large advantage in their gunfights against police. The cavalry armour of Napoleon, and the French, German, and British empires (heavy cavalry known as cuirassiers) were actively used through the 19th century right up to the first year of World War I, when French cuirassiers went to meet the enemy in armour outside of Paris. During the war both sides experimented with shrapnel armour and some soldiers used their own but dedicated ballistic armour such as the American Brewster Body Shield was not widely produced.

In 1916 General Adrian of the French army provided an abdominal shield which was light in weight (two pounds) and easy to wear. It was made of an oblong plate of metal bent in a curve and moulded somewhat to the abdomen, hip and groin guards were added to the abdominal shield. General Adrian devised a breastplate which joined the abdominal defence which was also provided with a gorget. About three thousand of these defences which weighed about five and a half pounds were made and they were given practical tests.

Plate armour briefly re-appeared during World War II on some Soviet Guard (elite) infantry units, who wore steel breastplates that could stop rounds fired by pistols and submachine guns. The Japanese and Americans made several prototypes but none were mass-produced due to their cost and the need for metal elsewhere. In the Korean War, body armour was re-introduced for U.S foot soldiers, and then to a greater extent in the Vietnam War. Modern U.S. soldiers in Iraq now always wear light-weight Kevlar helmets and armour vests, the latter often augmented with more-or-less rigid ceramic plate inserts. The U.S. Air Force used flak jackets as a form of plate armour. The 1970s introduction of aramid (Kevlar or Twaron) body armour brought sheet metal (especially titanium) trauma plates back into fashion as a form of rifle-grade add-on to flexible vests, and ballistic metals are gradually improving with stronger and lighter alloys being steadily developed. Lighter ceramic plates are still the choice of most first-world militaries, but titanium and ballistic steel are still in wide use by those wanting a less costly option.

Materials

The first plate armour was that of bronze, being worn by elite soldiers in Greek armies in particular. Bronze, whilst easier to work with, was much less commonly available (requiring copper and tin, which are almost never found in close proximity). Iron was, however, adequate enough for the task, eventually becoming more popular because of its strength as well as its far greater availability to be used in the advanced militaries of Europe and the Middle East.

Gradually methods of making steel were perfected and steel replaced iron in most capacities except munition armour. Steel was continually being made stronger and thicker to protect from bullets but eventually the needed protection was too heavy and expensive for most troops.

In the 20th century titanium and super-hardened "ballistic steel" came to be used for trauma plates. Eventually ceramic plates made from aluminium oxide and silicon carbide were introduced as well.

Effect on weapon development

Plate armour was virtually invulnerable to sword slashes. It also protects the wearer well against spear or pike thrusts and provides decent defence against blunt trauma.

The evolution of plate armour also triggered developments in the design of offensive weapons. While this armour was effective against cuts or blows, their weak points could be exploited by long tapered swords or other weapons designed for the purpose, such as poleaxes and halberds. The effect of arrows and bolts is still a point of contention in regards to plate armour. Longbows and crossbows could also pierce plate armour up to ranges of with a lucky shot, notably in battles such as the Battle of Visby, though historian Jean Froissart suggests that the success of such weapons at the Battle of Poitiers was less due to the bodkin arrows used by the English and more due to aiming for the side or rear of the armour, which is weaker. The evolution of the 14th-century plate armour also triggered the development of various polearms. They were designed to deliver a strong impact and concentrate energy on a small area and cause damage through the plate. Maces, war hammers and the hammer-heads of pollaxes (poleaxes) were used to inflict blunt trauma through armour.

Fluted plate was not only decorative, but also reinforced the plate against bending under slashing or blunt impact. This offsets against the tendency for flutes to catch piercing blows. In armoured techniques taught in the German school of swordsmanship, the attacker concentrates on these "weak spots", resulting in a fighting style very different from unarmoured sword-fighting. Because of this weakness most warriors wore a mail shirt (haubergeon or hauberk) beneath their plate armour (or coat-of-plates). Later, full mail shirts were replaced with mail patches, called goussets, sewn onto a gambeson or arming jacket. Further protection for plate armour was the use of small round plates called besagews that covered the armpit area and couters and poleyns with "wings" to protect the inside of the joint.
