Sovereignty can generally be defined as supreme, independent control and lawmaking authority over a territory. It finds expression in the power to rule and make law. Sovereignty entails hierarchy within a state as well as external autonomy for states. In any state, sovereignty is assigned to the person, body or institution that has the ultimate authority over other people and to change existing laws. In political theory, sovereignty is a substantive term designating supreme legitimate authority over some polity. Under international law, sovereign states are all considered equal, and no state can interfere with the internal affairs of another sovereign state. While Article 2(7) of the UN Charter explicitly recognizes the sovereignty of states, and in general there is a principle of non-interference in the domestic affairs of sovereign states, the UN Security Council’s Chapter VII powers clearly contemplate the use of force against a state when necessary to restore peace. Further, the recent Responsibility to Protect (R2P) authorizes the United Nations to take action to “avert a humanitarian catastrophe” within a state when that state’s government cannot or will not act.

A state is generally considered to have sovereignty over a territory when it has consistently exercised state authority there without objection from other states. De jure sovereignty refers to the legal right to do so; de facto sovereignty refers to the factual ability to do so. This can become an issue of special concern upon the failure of the usual expectation that de jure and de facto sovereignty exist at the place and time of concern, and reside within the same organization.

Light cavalry comprised lightly armed and armored cavalry troops mounted on fast horses, as opposed to heavy cavalry, where the mounted riders (and sometimes the warhorses) were heavily armored. The purpose of light cavalry was primarily raiding, reconnaissance, screening, skirmishing, patrolling, and tactical communications. Prior to the 17th century they were usually armed with swords, spears, javelins, or bows, and later on with sabres, pistols, shotguns, or carbines.

Light cavalry was used infrequently by Ancient Greeks (who used hippeis such as prodromoi or sarissophoroi) and Ancient Romans (who used auxiliaries such as equites Numidarum or equites Maurorum), but were more common among the armies of Eastern Europe, North Africa, West Asia, Central Asia, and East Asia. The Arabs, Cossacks, Hungarians, Huns, Kalmycks, Mongols, Turks, Parthians, and Persians were all proficient horse archers.

Heavy cavalry was a class of cavalry intended to deliver a battlefield charge and also to act as a tactical reserve; they are also often termed shock cavalry. Although their equipment differed greatly depending on the region and historical period, heavy cavalry were generally mounted on large powerful warhorses, wore body armor, and armed with either lances, swords, maces, flails (disputed), battle axes, or war hammers; their mounts may also have been protected by barding. They were distinct from light cavalry, who were intended for raiding, reconnaissance, screening, skirmishing, patrolling, and tactical communications.

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.

While ordinary objects such as rocks and bottles can be used as weapons, many objects are expressly designed for the purpose; these range from simple implements such as clubs and swords to complicated modern firearms, tanks, missiles and biological weapons. 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.

Decapitation is the total separation of the head from the body. Such an injury is invariably fatal to humans and all vertebrate animals, since it deprives the brain of oxygenated blood by way of severing the jugular vein and common carotid artery, while all other organs are deprived of the involuntary functions that are needed for the body to function.The term beheading refers to the act of deliberately decapitating a person, either as a means of murder or as an execution; it may be performed with an axe, sword, or knife, or by mechanical means such as a guillotine. An executioner who carries out executions by beheading is sometimes called a headsman. Accidental decapitation can be the result of an explosion, a car or industrial accident, improperly administered execution by hanging or other violent injury. The national laws of Saudi Arabia and Yemen permit beheading. Under Sharia, which exclusively applies to Muslims, beheading is also a legal punishment in Zamfara State, Nigeria. In practice, Saudi Arabia is the only country that continues to behead its offenders regularly as a punishment for capital crimes. Cases of decapitation by suicidal hanging, suicide by train decapitation and by guillotine are known.

Less commonly, decapitation can also refer to the removal of the head from a body that is already dead. This might be done to take the head as a trophy, as a secondary stage of an execution by hanging, for public display, to make the deceased more difficult to identify, for cryonics, or for other, more esoteric reasons.

A longsword (also spelled as long sword or long-sword) is a type of European sword characterized as having a cruciform hilt with a grip for primarily two-handed use (around 15 to 30 cm or 6 to 12 in), a straight double-edged blade of around 80 to 110 cm (31 to 43 in), and weighing approximately 2 to 3 kg (4 lb 7 oz to 6 lb 10 oz).

The "longsword" type exists in a morphological continuum with the medieval knightly sword and the Renaissance-era Zweihänder. It was prevalent during the late medieval and Renaissance periods (approximately 1350 to 1550), with early and late use reaching into the 11th and 17th centuries.

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.
