The word "armour" was introduced into use in the Middle Ages as a borrowing from the French. It is dated from 1297, as a "mail, defensive covering worn in combat" from Old French armoire, itself derived from the Latin armatura "arms and/or equipment" with the root arma "arms or gear".

Armour has been used throughout . It has been made from a variety of materials, beginning with rudimentary leather protection and evolving through
and metal plate into today's modern . For much of
the manufacture of metal personal armour has dominated the technology and employment of armour. Armour drove the development of many important technologies of the Ancient World, including wood , mining, , vehicle manufacture, leather processing, and later decorative metal working. Its production was influential in the , and furthered commercial development of metallurgy and engineering. Armour was the single most influential factor in the development of , which in turn revolutionised warfare.
armour, circa 1400 BCE
Significant factors in the development of armour include the economic and technological necessities of its production. For instance,
first appeared in Medieval Europe when water-powered trip hammers made the formation of plates faster and cheaper. Also, modern militaries usually do not equip their forces with the best armour available because it would be prohibitively expensive. At times the development of armour has paralleled the development of increasingly effective weaponry on the battlefield, with armourers seeking to create better protection without sacrificing mobility.
Well-known armour types in
include the , , and the
of the , the
of the early medieval age, and the full steel plate harness worn by later
, and breast and back plates worn by heavy cavalry in several European countries until the first year of World War I (1914–15). The
warriors of feudal Japan utilised
for hundreds of years up to the 19th century.
Cuirasses and helmets were manufactured in Japan as early as the 4th century.Tankō, worn by foot soldiers and keikō, worn by horsemen were both pre-samurai types of early
constructed from iron plates connected together by leather thongs. Japanese lamellar armour (keiko) passed through Korea and reached Japan around the 5th century. These early Japanese lamellar armours took the form of a sleeveless jacket and a helmet.
Armour did not always c sometimes no more than a helmet and leg plates were worn. The rest of the body was generally protected by means of a large shield. Examples of armies equipping their troops in this fashion were the Aztecs (13th to 15th century CE).
In East Asia many types of armour were commonly used at different times by various cultures including, , , , , ,
and . Around the dynastic Tang, Song, and early Ming Period, cuirasses and plates (mingguangjia) were also used, with more elaborate versions for officers in war. The Chinese, during that time used partial plates for "important" body parts instead of covering their whole body since too much plate armour hinders their martial arts movement. The other body parts were covered in cloth, leather, lamellar, and/or Mountain pattern. In pre-Qin dynasty times, leather armour was made out of various animals, with more exotic ones such as the rhinoceros.
, sometimes called "chainmail", made of interlocking iron rings is believed to have first appeared some time after 300 BCE. Its invention is credited to the , the Romans were thought to have adopted their design.
Gradually, small additional plates or discs of iron were added to the mail to protect vulnerable areas. Hardened leather and
construction were used for arm and leg pieces. The
was developed, an armour made of large plates sewn inside a textile or leather coat.
Early plate in Italy, and elsewhere in the 13th–15th century, were made of iron. Iron armour could be
to give a surface of harder steel. Plate armour became cheaper than mail by the 15th century as it required much less labour and labour had become much more expensive after the , though it did require larger furnaces to produce larger . Mail continued to be used to protect those joints which could not be adequately protected by plate, such as the armpit, crook of the elbow and groin. Another advantage of plate was that a lance rest could be fitted to the breast plate.
The small skull cap evolved into a bigger true helmet, the , as it was lengthened downward to protect the back of the neck and the sides of the head. Additionally, several new forms of fully enclosed helmets were introduced in the late 14th century.
Heavily armoured riders and their
, 16th century
Probably the most recognised style of armour in the World became the
associated with the
of the European , but continuing to the early 17th century
in all European countries.
By about 1400 the full harness of plate armour had been developed in armouries of Lombardy. Heavy cavalry dominated the battlefield for centuries in part because of their armour.
In the early 15th century, advances in weaponry allowed infantry to defeat armoured knights on the battlefield. The quality of the metal used in armour deteriorated as armies became bigger and armour was made thicker, necessitating breeding of larger cavalry horses. If during the 14–15th centuries armour seldom weighed more than 15 kg, then by the late 16th century it weighed 25 kg. The increasing weight and thickness of late 16th century armour therefore gave substantial resistance.
In the early years of low velocity firearms, full suits of armour, or breast plates actually stopped bullets fired from a modest distance. Crossbow bolts, if still used, would seldom penetrate good plate, nor would any bullet unless fired from close range. In effect, rather than making plate armour obsolete, the use of firearms stimulated the development of plate armour into its later stages. For most of that period, it allowed horsemen to fight while being the targets of defending arquebuseers without being easily killed. Full suits of armour were actually worn by generals and princely commanders right up to the second decade of the 18th century. It was the only way they could be mounted and survey the overall battlefield with safety from distant musket fire.
The horse was afforded protection from lances and infantry weapons by steel plate . This gave the horse protection and enhanced the visual impression of a mounted knight. Late in the era, elaborate barding was used in parade armour.
Gradually, starting in the mid-16th century, one plate element after another was discarded to save weight for foot soldiers.
Back and breast plates continued to be used throughout the entire period of the 18th century and through Napoleonic times, in many European (heavy) cavalry units, until the early 20th century. From their introduction,
could pierce plate armour, so cavalry had to be far more mindful of the fire. In Japan armour continued to be used until the end of the samurai era, with the last major fighting in which armour was used happening in 1868.
had one last short lived use in 1877 during the .
Though the age of the knight was over, armour continued to be used in many capacities. Soldiers in the American Civil War bought iron and steel vests from peddlers (both sides had considered but rejected body armour for standard issue). The effectiveness of the vests varied widely—some successfully deflected bullets and saved lives, but others were poorly made and resulted in tragedy for the soldiers. In any case the vests were abandoned by many soldiers due to their weight on long marches as well as the stigma they got for being cowards from their fellow troops.
At the start of World War I, thousands of the French
rode out to engage the German Cavalry who likewise used helmets and armour. By that period, the shiny armour plate was covered in dark paint and a canvas wrap covered their elaborate Napoleonic style helmets. Their armour was meant to protect only against
and light . The cavalry had to beware of high velocity

Today, , also known as , made of ballistic cloth (e.g. , , ,
etc.) and ceramic or metal plates are common among police forces, ,
and some branches of the military.
The US Army has adopted , which uses Enhanced Small Arms Protective Inserts (E-S.A.P.I) in the chest, sides and back of the armour. Each plate is rated to stop a range of ammunition including 3 hits from a

Ironclads were designed for several roles, including as high seas , coastal defence ships, and long-range . The rapid evolution of warship design in the late 19th century transformed the ironclad from a wooden-hulled vessel which carried sails to supplement its steam engines into the steel-built, turreted battleships and cruisers familiar in the 20th century. This change was pushed forward by the development of heavier naval guns (the ironclads of the 1880s carried some of the heaviest guns ever mounted at sea)[], more sophisticated steam engines, and advances in metallurgy which made steel shipbuilding possible.
The rapid pace of change in the ironclad period meant that many ships were obsolete as soon as they were complete, and that naval tactics were in a state of flux. Many ironclads were built to make use of the

There is no clear end to the ironclad period, but towards the end of the 1890s the term ironclad dropped out of use. New ships were increasingly constructed to a standard pattern and designated battleships or .

Towards the end of World War I, armies on both sides were experimenting with plate armour as protection against
and ricocheting projectiles. The first proposal for a tank was by the Austrian Oberleutenant
who, in 1911, proposed a design for "motor artillery" (Motorengeschütz) with a turret, but his design never progressed beyond a German patent in 1912.
Armoured cars were put into use by the British on the Western Front. Initially an innovation to aid the recovery of downed pilots, they were sidelined when the front became static. They continued to be used in the more open Middle East battlefields.

In contrast to World War II, Germany fielded very few tanks during WWI, with only 15 of the
type being produced in Germany during the war. Most German tanks were captured British ones. The first tank versus tank action took place on 24 April 1918 at , when three British
met an advance of three German , supported by infantry. Tanks were knocked out on both sides, but the German attack failed and they retreated.
Mechanical problems, poor mobility and piecemeal tactical deployment limited the military significance of the tank in World War I and the tank did not fulfil its promise of rendering trench warfare . Nonetheless, it was clear to military thinkers on both sides that tanks would play a significant role in future conflicts.

fragments, and greater mobility in more terrain types. The basic APC design was substantially expanded to an
