A weapon , arm , or armament is any implement or device that is used to deter, threaten, inflict physical damage, harm, or kill . Weapons are used to increase the efficacy and efficiency of activities such as hunting , crime (e.g., murder ), law enforcement , self-defense , warfare , or suicide . In a broader context, weapons may be construed to include anything used to gain a tactical, strategic, material, or mental advantage over an adversary or enemy target.
65-519: The falx was a weapon with a curved blade that was sharp on the inside edge used by the Thracians and Dacians . The name was later applied to a siege hook used by the Romans. Falx is a Latin word originally meaning ' sickle ' but was later used to mean any of a number of tools that had a curved blade that was sharp on the inside edge like a sickle. Falx was thus also used to mean
130-407: A commercial industry involved in the research and development , engineering , production, and servicing of military material, equipment, and facilities. Many industrialized countries have a domestic arms industry to supply their own military forces, and some also have a substantial trade in weapons for use by their citizens for self-defense, hunting, or sporting purposes. Contracts to supply
195-399: A blade length that varied but was usually around 16 inches (41 cm) long with a handle one-third longer than the blade. The two-handed falx was a polearm . It consisted of a 3-foot-long (0.91 m) wooden shaft with a long curved iron blade of nearly-equal length attached to the end. Archaeological evidence indicates that the one-handed falx was also used two-handed. The blade
260-405: A given country's military are awarded by governments, making arms contracts of substantial political importance. The link between politics and the arms trade can result in the development of a " military–industrial complex ", where the armed forces, commerce, and politics become closely linked. According to research institute SIPRI, the volume of international transfers of major weapons in 2010–2014
325-522: A low gold content in Roman money as directed by Emperor Nero . Confirmed rumors of Dacian gold and other valuable trade resources inflamed the conflict, as did the Dacians' defiant behaviour, as they were "unbowed and unbroken". However, other pressing reasons motivated them to action. Researchers estimate that only ten percent of barbarians such as Spanish and Gallic warriors had access to swords, usually
390-858: A major driver of cultural evolution and human history up to today since weapons are a type of tool that is used to dominate and subdue autonomous agents such as animals and, by doing so, allow for an expansion of the cultural niche, while simultaneously other weapon users (i.e., agents such as humans, groups, and cultures) are able to adapt to the weapons of enemies by learning, triggering a continuous process of competitive technological, skill, and cognitive improvement ( arms race ). The use of objects as weapons has been observed among chimpanzees , leading to speculation that early hominids used weapons as early as five million years ago. However, this cannot be confirmed using physical evidence because wooden clubs, spears, and unshaped stones would have left an ambiguous record. The earliest unambiguous weapons to be found are
455-474: A manner analogous to the bill-guisarme . The single-handed falx might have been inspired by the sickle, although agricultural sickles of the time were typically quite small – no more than 30 cm or so in length. At the time of the Dacian wars, producing a long, sharp blade was technically challenging. As such, it might be that the larger two-handed falx was a high-status weapon and used only by
520-466: A number of issues around the potential ongoing risks from deployed weapons, the safe storage of weapons, and their eventual disposal when they are no longer effective or safe. Strange and exotic weapons are a recurring feature or theme in science fiction . In some cases, weapons first introduced in science fiction have now become a reality. Other science fiction weapons, such as force fields and stasis fields , remain purely fictional and are often beyond
585-403: A row of pteruges was added to the sleeves, a double row of pteruges was added to the skirt and a heavily padded vestment was worn underneath them. Roman armour of the time left limbs unprotected; Trajan introduced the use of greaves and an arm protector ( manica ) for the right arm, which had previously been used only by gladiators, and which was never used again by soldiers once
650-410: A shield in two at a single blow. Alternatively, it might have been used as a hook, pulling away shields and cutting at vulnerable limbs, or striking the edge of a strong shield. The inward curving point was still able to pierce the armour or flesh of the target behind the shield, rendering even the most reinforced shields much less effective against a falx wielder. Trajan's column is a monument to
715-450: A superior cutting action. This drastic curve rendered the falx a purely offensive weapon to be used against a broken or routing force. Typically, an enemy would be broken by a sustained hail of missile fire from javelin, dart, bow, sling, and stone throwing troops before being chased down and cut to pieces by the falx wielders. The ancestor of the two-handed falx may have been a farming implement used as an improvised weapon, in

#1732782937774780-461: A theme when it touches on deeper concerns, often motivated by contemporary issues. One example is science fiction that deals with weapons of mass destruction like doomsday devices . Trajan%27s Dacian Wars Trajan's Dacian Wars (101–102, 105–106) were two military campaigns fought between the Roman Empire and Dacia during Emperor Trajan 's rule. The conflicts were triggered by
845-451: A war of defense. As such, the new Emperor Trajan , himself an experienced soldier and tactician, began preparing for war. That Dacia was considered a substantial threat can be seen by the fact that Trajan withdrew troops from other borders leaving them dangerously undermanned. After gaining the Senate's blessing for war, by 101 Trajan was ready to advance on Dacia. This was a war in which
910-617: A worldwide crusade in the 1920s. Poison gas did not win battles, and the generals did not want it. The soldiers hated it far more intensely than bullets or explosive shells. By 1918, chemical shells made up 35 percent of French ammunition supplies, 25 percent of British, and 20 percent of American stock. The “Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous, or Other Gases and of Bacteriological Methods of Warfare”, also known as
975-485: Is also largely stylized, with the sculptor believed to have worked from Trajan's now lost commentary and unlikely to have witnessed the events himself. A further problem is that most of the weapons on the monument were made of metal, which have since disappeared. The Adamclisi monument, built by Trajan to commemorate the Romans who lost their lives in the Dacian counterattack in Moesia , is thought to have been constructed by
1040-464: Is clear that these are late modifications because they are roughly applied across existing embossed decoration. The legions also reintroduced the wearing of lorica hamata and lorica squamata for the Dacia campaign as both were more flexible than the newer segmentata armour which was able to distribute damage more widely. In addition, both these older armour styles had unique modifications,
1105-499: Is the trafficking of contraband weapons and ammunition . What constitutes legal trade in firearms varies widely, depending on local and national laws. In 2001, the United Nations had made a protocol against the manufacturing and trafficking of illicit arms. This protocol made governments dispose illegal arms, and to licence new firearms being produced, to ensure them being legitimate. It was signed by 122 parties. There are
1170-501: The falx was most efficient when targeting the head, shoulders, legs and especially the right (sword) arm, which was generally exposed. A legionary who had lost the use of his right arm became a serious liability to his unit in battle. During the conquest of Dacia by Trajan the Roman army adapted personal equipment while on campaign, and it seems likely that this was a response to this deadly weapon. Roman legionaries had transverse reinforcing iron straps applied to their helmets - it
1235-467: The Geneva Protocol , was issued in 1925 and was accepted as policy by all major countries. In 1937, poison gas was manufactured in large quantities but not used except against nations that lacked modern weapons or gas masks. Many modern military weapons, particularly ground-based ones, are relatively minor improvements to weapon systems developed during World War II. World War II marked perhaps
1300-548: The Schöningen spears , eight wooden throwing spears dating back more than 300,000 years. At the site of Nataruk in Turkana, Kenya, numerous human skeletons dating to 10,000 years ago may present evidence of traumatic injuries to the head, neck, ribs, knees, and hands, including obsidian projectiles embedded in the bones that might have been caused by arrows and clubs during conflict between two hunter-gatherer groups. But
1365-580: The arquebus were much more powerful than human-powered weapons. Firearms became increasingly important and effective during the 16th–19th centuries, with progressive improvements in ignition mechanisms followed by revolutionary changes in ammunition handling and propellant. During the American Civil War , new applications of firearms, including the machine gun and ironclad warship , emerged that would still be recognizable and useful military weapons today, particularly in limited conflicts . In

#17327829377741430-585: The trireme , were in use by the 7th century BC. During the first First Punic War , the use of advanced warships contributed to a Roman victory over the Carthaginians. European warfare during post-classical history was dominated by elite groups of knights supported by massed infantry (both in combat and ranged roles). They were involved in mobile combat and sieges , which involved various siege weapons and tactics. Knights on horseback developed tactics for charging with lances , providing an impact on
1495-409: The 19th century, warship propulsion changed from sail power to fossil fuel -powered steam engines . Since the mid-18th century North American French-Indian war through the beginning of the 20th century, human-powered weapons were reduced from the primary weaponry of the battlefield to yielding gunpowder-based weaponry. Sometimes referred to as the "Age of Rifles", this period was characterized by
1560-569: The 4th century BC. Cavalry developed once horses were bred to support the weight of a human. The horse extended the range and increased the speed of attacks. Alexander's conquest saw the increased use of spears and shields in the Middle East and Western Asia as a result Greek culture spread which saw many Greek and other European weapons be used in these regions and as a result many of these weapons were adapted to fit their new use in war In addition to land-based weaponry, warships , such as
1625-464: The Dacia campaign concluded. The Thracians also made use of the falx . They also used the rhomphaia , a weapon very similar to the two-handed falx but less curved. The two-handed falx is clearly related to the Thracian rhomphaia . It is a derivative of both the sword and the spear, having evolved from a spear to a polearm before becoming more dramatically curved to facilitate
1690-789: The Dacian Wars marked a triumph for Rome and its armies. Trajan announced 123 days of celebrations throughout the Empire. Dacia's rich gold mines were secured and it is estimated that Dacia then contributed 700 million Denarii per annum to the Roman economy, providing finance for Rome's future campaigns and assisting with the rapid expansion of Roman towns throughout Europe. The remains of the mining activities are still visible, especially at Roșia Montană. One hundred thousand male slaves were sent back to Rome; and to discourage future revolts, legions XIII Gemina and V Macedonica were permanently posted in Dacia. The conquered half (southern) of Dacia
1755-472: The Dacian king Decebalus used the Roman annual subsidy of 8 million sesterces and craftsmen in trades devoted to both peace and war, and war machines intended to defend the empire's borders to fortify his own defences instead. Despite some co-operation on the diplomatic front with Domitian, Decebalus continued to oppose Rome. At the time, Rome was suffering from economic difficulties largely brought on by military invasions throughout Europe and in part due to
1820-464: The Dacians fighting with no armour apart from a shield, although some on the Adamclisi are wearing helmets. Some historians believe that armour was not depicted to differentiate Dacians from Romans, as both used the same style of shield. Other sources indicate that Dacians by this time had undergone Romanisation, used Roman military tactics, and sometimes wore Roman style scale armour. It is likely that
1885-701: The Iatrus (Yantra) and the Rositsa rivers in readiness for the attack by the Sarmatian Roxolani tribe from north of the Danube (who were allied to the Dacians), and resulted in a Roman victory for which the city was named. In 102 Decebalus chose to make peace once it became clear that the Roman advance towards Sarmizegetusa was unstoppable. The war had concluded with an important Roman victory and with
1950-468: The Roman military's ingenuity and engineering were well demonstrated. The Roman offensive was spearheaded by two legionary columns, marching straight to the heart of Dacia, burning towns and villages en route. Trajan defeated a Dacian army at the Third Battle of Tapae . In the winter of 101-2, the Roman army under Trajan had been amassed near the later city of Nicopolis ad Istrum at the junction of
2015-442: The beginning of the implementation of firearms in western warfare. Guns and rockets were introduced to the battlefield. Firearms are qualitatively different from earlier weapons because they release energy from combustible propellants , such as gunpowder , rather than from a counterweight or spring. This energy is released very rapidly and can be replicated without much effort by the user. Therefore, even early firearms such as

2080-434: The best warriors. Similarly, there are the sica and the rhomphaia . The sica is a much smaller variation, some with very dramatic curves or bends. The rhomphaia is often larger and used with two hands, though there were some one handed ones. Weapon While ordinary objects such as sticks , rocks , bottles , chairs , and vehicles can be used as weapons , many objects are expressly designed for
2145-606: The constant Dacian threat on the Danubian province of Moesia and also by the increasing need for resources of the economy of the Empire. Throughout the 1st century, Roman policy dictated that threats from neighbouring nations and provinces were to be contained promptly. Dacia had been on the Roman agenda since before the days of Caesar when the Dacians defeated a Roman army at the Battle of Histria . Domitian's Dacian War had re-established peace with Dacia in 89 AD. However,
2210-498: The development of ancient weapons. It was not the introduction of early Iron Age swords , however, as they were not superior to their bronze predecessors, but rather the domestication of the horse and widespread use of spoked wheels by c. 2000 BC . This led to the creation of the light, horse-drawn chariot , whose improved mobility proved important during this era. Spoke-wheeled chariot usage peaked around 1300 BC and then declined, ceasing to be militarily relevant by
2275-426: The development of firearms for infantry and cannons for support, as well as the beginnings of mechanized weapons such as the machine gun . Artillery pieces such as howitzers were able to destroy masonry fortresses and other fortifications, and this single invention caused a revolution in military affairs , establishing tactics and doctrine that are still in use today. An important feature of industrial age warfare
2340-428: The development, production, stockpiling, proliferation, and usage of weapons, from small arms and heavy weapons to weapons of mass destruction . Arms control is typically exercised through the use of diplomacy, which seeks to impose such limitations upon consenting participants, although it may also comprise efforts by a nation or group of nations to enforce limitations upon a non-consenting country. Arms trafficking
2405-563: The emperor's conquest of Dacia. The massive base is covered with reliefs of trophies of Dacian weapons and includes several illustrations of the two-handed falx . The column itself has a helical frieze that tells the story of the Dacian wars. On the frieze, almost all the Dacians that are armed have shields and therefore cannot be using two-handed falx . The exact weapon of those few shown without shields cannot be determined with certainty. The frieze of Trajan's column also shows Dacians using smaller, sword-sized falx . However, this column
2470-409: The end of this period revolutionized warfare. Formations of musketeers , protected by pikemen , came to dominate open battles, and the cannon replaced the trebuchet as the dominant siege weapon . The Ottoman used the cannon to destroy much of the fortifications at Constantinople which would change warfare as gunpowder became more available and technology improved The European Renaissance marked

By contrast, infantry, in the age before structured formations, relied on cheap, sturdy weapons such as spears and billhooks in close combat and bows from a distance. As armies became more professional, their equipment was standardized, and infantry transitioned to pikes . Pikes are normally seven to eight feet in length and used in conjunction with smaller sidearms (short swords). In Eastern and Middle Eastern warfare, similar tactics were developed independent of European influences. The introduction of gunpowder from Asia at
2600-474: The establishment of a garrison and an acting governor at Sarmizegetusa . A bridge later known as Trajan's bridge was constructed across the Danube at Drobeta to assist with the legionaries' advance. This bridge, probably the biggest at that time and for centuries to come, was designed by Apollodorus of Damascus and was meant to help the Roman army advance faster in Dacia in case of a future war. According to
2665-461: The first war, Decebalus complied with Rome for a time, but was soon inciting revolt among tribes against them and pillaging Roman colonies across the Danube. True to his intrepid and optimistic nature, Trajan rallied his forces in AD 105 for a second war. Like the first conflict, the second war involved several skirmishes that proved costly to the Roman military. Faced with large numbers of allied tribes,

2730-470: The interpretation of warfare at Nataruk has been challenged due to conflicting evidence. The earliest ancient weapons were evolutionary improvements of late Neolithic implements, but significant improvements in materials and crafting techniques led to a series of revolutions in military technology . The development of metal tools began with copper during the Copper Age (about 3,300 BC) and
2795-476: The interwar period (between WWI and WWII) with the continuous evolution of weapon systems by all major industrial powers. The major armament firms were Schneider-Creusot (based in France), Škoda Works (Czechoslovakia), and Vickers (Great Britain). The 1920s were committed to disarmament and the outlawing of war and poison gas, but rearmament picked up rapidly in the 1930s. The munitions makers responded nimbly to
2860-427: The legions struggled to attain a decisive victory, resulting in a second temporary peace. Eventually, goaded by the behaviour of Decebalus and his repeated violations of the treaty, Rome again brought in reinforcements, took the offensive and prevailed in 105. The next year they gradually conquered the mountain fortress system that surrounded the Dacian capital, Sarmizegetusa . The final decisive battle took place near
2925-572: The manufacture, sale, transfer, possession, modification, and use of small arms by civilians. Countries that regulate access to firearms will typically restrict access to certain categories of firearms and then restrict the categories of persons who may be granted a license for access to such firearms. There may be separate licenses for hunting, sport shooting (a.k.a. target shooting), self-defense, collecting, and concealed carry, with different sets of requirements, permissions, and responsibilities. International treaties and agreements place restrictions on
2990-453: The most frantic period of weapon development in the history of humanity. Massive numbers of new designs and concepts were fielded, and all existing technologies were improved between 1939 and 1945. The most powerful weapon invented during this period was the nuclear bomb ; however, many other weapons influenced the world, such as jet aircraft and radar , but were overshadowed by the visibility of nuclear weapons and long-range rockets. Since
3055-449: The nobility. By contrast Dacia had rich resources of iron and copper and were prolific metal workers. A large percentage of Dacians owned swords, greatly reducing Rome's military advantage. Dacia sported 250,000 potential combatants, enough to enable an invasion. It was allied to several of its neighbours and on friendly terms with others that Rome considered enemies. Rome had no concrete defense policy and would not have been able to sustain
3120-405: The nobles at least wore armour and, combined with the falx , the Dacians would have been a formidable threat. Marcus Cornelius Fronto described the large gaping wounds that a falx inflicted, and experiments have shown that a blow from a falx easily penetrated the Romans' lorica segmentata , enough to incapacitate or kill a majority of opponents. These experiments also show that
3185-404: The peace terms, Decebalus got technical and military reinforcement from the Romans in order to create a powerful allied zone against the dangerous possible expeditions from the northern and eastern territories by hostile migrating peoples. The resources were instead used to rebuild Dacian fortresses and strengthen the army. Soon thereafter Decebalus turned against the Romans once again. Following
3250-465: The point of being able to ensure the destruction of the Earth by 100 fold, a new tactic had to be developed. With this realization, armaments development funding shifted back to primarily sponsoring the development of conventional arms technologies for support of limited wars rather than total war . The arms industry is a global industry that involves the sale and manufacture of weaponry. It consists of
3315-412: The purpose; these range from simple implements such as clubs , axes , spears , and swords to complicated modern firearms , tanks , intercontinental ballistic missiles , biological weapons , and cyberweapons . Something that has been repurposed, converted, or enhanced to become a weapon of war is termed weaponized , such as a weaponized virus or weaponized laser . The use of weapons has been

The main purchasers of munitions from the big three companies were Romania, Yugoslavia, Greece, and Turkey – and, to a lesser extent, Poland, Finland, the Baltic States, and the Soviet Union. Realistic critics understood that war could not really be outlawed, but its worst excesses might be banned. Poison gas became the focus of
3445-553: The realization of mutual assured destruction (MAD), the nuclear option of all-out war is no longer considered a survivable scenario. During the Cold War in the years following World War II, both the United States and the Soviet Union engaged in a nuclear arms race . Each country and their allies continually attempted to out-develop each other in the field of nuclear armaments. Once the joint technological capabilities reached
3510-613: The realms of known physical possibility. At its most prosaic, science fiction features an endless variety of sidearms , mostly variations on real weapons such as guns and swords . Among the best-known of these are the phaser used in the Star Trek television series, films, and novels, and the lightsaber and blaster featured in the Star Wars movies, comics, novels, and TV series. In addition to adding action and entertainment value, weaponry in science fiction sometimes becomes
3575-478: The soldiers who fought there, so it may be more accurate. This column shows four distinct types of falx , whereas Trajan's shows only one type that does not resemble any on the Adamclisi monument. Because of this, historians disagree on which depiction is correct, but it has been pointed out that if the Trajan's column falx are correct, then there would have been no need to modify Roman armour. Both columns show
3640-402: The walls of Sarmizegetusa, presumably during the summer of 106, with the participation of the legions II Adiutrix and IV Flavia Felix and a detachment ( vexillatio ) from VI Ferrata . The Dacians repelled the first attack, but the Romans, helped by a treacherous local nobleman, found and destroyed the water pipes of the Dacian capital. Running out of water and food the city fell and
3705-600: The weapon of the Thracians and Dacians, and the Roman siege hook. In Latin texts, the weapon was described as an ensis falcatus (whence falcata ) by Ovid in Metamorphose and as a falx supina by Juvenal in Satiriae . The Dacian falx came in two sizes: one-handed and two-handed. The shorter variant was called sica (sickle) in the Dacian language ( Valerius Maximus , III, 2.12) with
3770-461: The wide introduction of aircraft into warfare and naval warfare with the introduction of aircraft carriers . Above all, it promised the military commanders independence from horses and a resurgence in maneuver warfare through the extensive use of motor vehicles. The changes that these military technologies underwent were evolutionary but defined their development for the rest of the century. This period of innovation in weapon design continued in
3835-410: Was technological escalation – innovations were rapidly matched through replication or countered by another innovation. World War I marked the entry of fully industrialized warfare as well as weapons of mass destruction ( e.g. , chemical and biological weapons ), and new weapons were developed quickly to meet wartime needs. The technological escalation during World War I was profound, including
3900-434: Was 16 percent higher than in 2005–2009, and the arms sales of the world's 100 largest private arms-producing and military services companies totaled $ 420 billion in 2018. The production, possession, trade, and use of many weapons are controlled. This may be at a local or central government level or by international treaty. Examples of such controls include: All countries have laws and policies regulating aspects such as

The two wars were notable victories in Rome's extensive expansionist campaigns, gaining Trajan the people's admiration and support.

Trajan began extensive building projects and was so prolific in claiming credit that he

During the Bronze Age, the first defensive structures and fortifications appeared as well, indicating an increased need for security. Weapons designed to breach fortifications followed soon after, such as the battering ram , which was in use by 2500 BC. The development of ironworking around 1300 BC in Greece had an important impact on

Trajan became an honorable civil leader, improving Rome's civic infrastructure, thereby paving the way for internal growth and reinforcement of the Empire as a whole. As a consequence of the war, Dacia went through a huge demographic change. In the province of Dacia, out of 3000 identified personal names only 60 were of Dacian, while 2200 were of Roman origin. ...Trajan, after he had subdued Dacia, had transplanted thither an infinite number of men from

Thanks to the treason of a confidant of the Dacian king, Bicilis, the Romans found Decebalus's treasure in the river of Sargesia/Sargetia - a fortune estimated by Carcopino at 165,500 kg of gold and 330,000 kg of silver. The last battle took place at Porolissum (Moigrad). The conclusion of

However, it left its user vulnerable because, being a two-handed weapon, the warrior could not also make use of a shield. It may be imagined that the length of the two-handed falx allowed it to be wielded with great force, the point piercing helmets and the blade splitting shields – it was said to be capable of splitting
