Bayonet in the context of "Lee–Enfield"

A pike is a long thrusting spear formerly used in European warfare from the Late Middle Ages and most of the early modern period, and wielded by foot soldiers deployed in pike square formation, until it was largely replaced by bayonet-equipped muskets. The pike was particularly well known as the primary weapon of Spanish tercios, Swiss mercenaries, German Landsknecht units and French sans-culottes. A similar weapon, the sarissa, had been used in antiquity by Alexander the Great's Macedonian phalanx infantry.

The balance of power theory in international relations suggests that states may secure their survival by preventing any one state from gaining enough military power to dominate all others. If one state becomes much stronger, the theory predicts it will take advantage of its weaker neighbors, thereby driving them to unite in a defensive coalition. Some realists maintain that a balance-of-power system is more stable than one with a dominant state, as aggression is unprofitable when there is equilibrium of power between rival coalitions.

When threatened, states may seek safety either by balancing, allying with others against the prevailing threat; or bandwagoning, aligning themselves with the threatening power. Other alliance tactics include buck passing and chain-ganging. Realists have long debated how the polarity of a system impacts the choice of tactics; however, it is generally agreed that in bipolar systems, each great power has no choice but to directly confront the other. Along with debates between realists about the prevalence of balancing in alliance patterns, other schools of international relations, such as constructivists, are also critical of the balance of power theory, disputing core realist assumptions regarding the international system and the behavior of states.

An edged weapon, or bladed weapon, is a hand-to-hand combat weapon with a cutting edge. Bladed weapons include swords, daggers, knives, and bayonets. Edged weapons are used to cut, hack, or slash; some edged weapons (such as many kinds of swords) may also permit thrusting and stabbing. Edged weapons contrast with blunt weapons such as maces, and with pointed weapons such as spears.

Many edged agricultural tools such as machetes, hatchets, axes, sickles, sling blades, and scythes, have been used as improvised weapons by peasantry, militia, or irregular forces – particularly as an expedient for defence.

The hilt (rarely called a haft or shaft) is the handle of a knife, dagger, sword, or bayonet, consisting of a guard, grip, and pommel. The guard may contain a crossguard or quillons. A tassel or sword knot may be attached to the guard or pommel.

Heavy infantry consisted of heavily armed and armoured infantrymen who were trained to mount frontal assaults and/or anchor the defensive center of a battle line. This differentiated them from light infantry who were relatively mobile and lightly armoured skirmisher troops intended for screening, scouting, and other tactical roles unsuited to soldiers carrying heavier loads. Heavy infantry typically made use of dense battlefield formations, such as shield wall or phalanx, multiplying their effective weight of arms with force concentration.

Heavy infantry were critical to many ancient armies, which first attested by the Sumerians in the Stele of the Vultures. It was also used by rival Assyrian and Persian Sparabara, then by Greek hoplites, Macedonian phalangites, and Roman legionaries. After the fall of Rome, heavy infantry declined in Europe but returned to dominance in the Late Middle Ages with Swiss pikemen and German Landsknechts. With the rise of firearms during early modern warfare, dense formations became increasingly infeasible, and heavy armours were either ineffective or too cumbersome to be tactically useful. By the early 18th century, heavy infantry were replaced by line infantry armed with muskets and bayonets and wearing little to no armour.

A musket is a muzzle-loaded long gun that appeared as a smoothbore weapon in the early 16th century, at first as a heavier variant of the arquebus, capable of penetrating plate armour. By the mid-16th century, this type of musket gradually disappeared as the use of heavy armour declined, but musket continued as the generic term for smoothbore long guns until the mid-19th century. In turn, this style of musket was retired in the 19th century when rifled muskets (simply called rifles in modern terminology) using the Minié ball (invented by Claude-Étienne Minié in 1849) became common. The development of breech-loading firearms using self-contained cartridges, introduced by Casimir Lefaucheux in 1835, began to make muskets obsolete. The first reliable repeating rifles, the 1860 Henry rifle and its 1866 descendant the Winchester rifle, superseded muskets entirely. Repeating rifles quickly established themselves as the standard for rifle design, ending the era of the musket.

Liberty Leading the People (French: La Liberté guidant le peuple [la libɛʁte ɡidɑ̃ lə pœpl]) is a painting of the Romantic era by the French artist Eugène Delacroix, commemorating the July Revolution of 1830 that toppled King Charles X (r. 1824–1830). A bare-breasted "woman of the people" with a Phrygian cap personifying the concept and Goddess of Liberty, accompanied by a young boy brandishing a pistol in each hand, leads a group of various people forward over a barricade and the bodies of the fallen while holding aloft the flag of the French Revolution—the tricolour, which again became France's national flag after these events—in one hand, and brandishing a bayonetted musket with the other. The figure of Liberty is also viewed as a symbol of France and the French Republic known as Marianne. The painting is sometimes wrongly thought to depict the French Revolution of 1789.

Liberty Leading the People is exhibited in the Louvre in Paris.

A mass stabbing is a single incident in which multiple victims are injured or killed with a sharp object thrusted at the victims, piercing through the skin and injuring the victims. Examples of sharp instruments used in mass stabbings may include kitchen knives, utility knives, sheath knives, scissors, katanas, icepicks, bayonets, axes, machetes and glass bottles. Knife crime poses security threats to many countries around the world.

There are many different factors that could lead to a mass stabbing. This may include social inequality, abuse of alcohol and other drugs, easy access to weapons, social and cultural norms, religious and political reasons, among others.

A fuller is a rounded or beveled longitudinal groove or slot along the flat side of a blade (e.g., a sword, knife, or bayonet) that serves to both lighten and stiffen the blade, when considering its reduced weight.

Cutting or grinding a fuller into an existing blade will decrease its absolute stiffness due to the removal of material, but much of the strength remains due to the geometry of its shape. When the groove is forged into the blade, it achieves a similar reduction in weight with a relatively small reduction in strength without the wasted material produced by grinding. When impressed during forging, it may be made using a blacksmithing tool that is also called a fuller, a form of spring swage.
