Piracy in the context of "No quarter"

Capital punishment, also known as the death penalty and formerly called judicial homicide, is the state-sanctioned killing of a person as punishment for actual or supposed misconduct. The sentence ordering that an offender be punished in such a manner is called a death sentence, and the act of carrying out the sentence is an execution. A prisoner who has been sentenced to death and awaits execution is condemned and is commonly referred to as being "on death row". Etymologically, the term capital (lit. 'of the head', derived via the Latin capitalis from caput, "head") refers to execution by beheading, but executions are carried out by many methods.

Crimes that are punishable by death are known as capital crimes, capital offences, or capital felonies, and vary depending on the jurisdiction, but commonly include serious crimes against a person, such as murder, assassination, mass murder, child murder, aggravated rape, terrorism, aircraft hijacking, war crimes, crimes against humanity, and genocide, along with crimes against the state such as attempting to overthrow government, treason, espionage, sedition, and piracy. Also, in some cases, acts of recidivism, aggravated robbery, and kidnapping, in addition to drug trafficking, drug dealing, and drug possession, are capital crimes or enhancements. However, states have also imposed punitive executions, for an expansive range of conduct, for political or religious beliefs and practices, for a status beyond one's control, or without employing any significant due process procedures. Judicial murder is the intentional and premeditated killing of an innocent person by means of capital punishment. For example, the executions following the show trials in the Soviet Union during the Great Purge of 1936–1938 were an instrument of political repression.

A letter of marque and reprisal was a government license in the Age of Sail that authorized a private person, known as a privateer or corsair, to attack and capture vessels of a foreign state at war with the issuer, licensing international military operations against a specified enemy as reprisal for a previous attack or injury. Captured naval prizes were judged before the government's admiralty court for condemnation and transfer of ownership to the privateer.

A common practice among Europeans from the late Middle Ages to the 19th century, cruising for enemy prizes with a letter of marque was considered an honorable calling that combined patriotism and profit. Such legally authorized privateering contrasted with unlicensed captures of random ships, known as piracy, which was universally condemned. In practice, the differences between privateers and pirates were sometimes slight, even merely a matter of interpretation.

A privateer is a private person or vessel which engages in commerce raiding under a commission of war. Since robbery under arms was a common aspect of seaborne trade, until the early 19th century all merchant ships carried arms. A sovereign or delegated authority issued commissions, also referred to as letters of marque, during wartime. The commission empowered the holder to carry on all forms of hostility permissible at sea by the usages of war. This included attacking foreign vessels and taking them as prizes and taking crews prisoner for exchange. Captured ships were subject to condemnation and sale under prize law, with the proceeds divided by percentage between the privateer's sponsors, shipowners, captains and crew. A percentage share usually went to the issuer of the commission (i.e. the sovereign). Most colonial powers, as well as other countries, engaged in privateering.

Privateering allowed sovereigns to augment their naval forces at relatively low cost by mobilizing privately owned armed ships and sailors to supplement state power. For participants, privateering provided the potential for a greater income and profit than obtainable as a merchant seafarer or fisher while avoiding the dangers associated with outright piracy. However, the line between privateers and pirates was not always clear.

A period of Albanian piracy (Albanian: Piratëria shqiptare) occurred from the 15th to the 19th centuries, during which Albanian pirates plundered and raided ships. These pirates were based mainly in Ulcinj, but were also found in Bar and Ragusa (now Dubrovnik), and had connections with North Africa.

They plundered European ships mainly for the Ottoman Empire, disrupting the Mediterranean economy and forcing European powers to intervene. Some of the pirate leaders from Ulcinj, such as Lika Ceni and Hadji Alia, were well-known during this period. The Porte gave the name "name-i hümayun" ("imperial letters"), bilateral agreements to settle armed conflicts. The Ottoman Empire was also known to hire these pirates during periods of war. Some of the most famous barbary pirates of the Mediterranean Sea were the Ottoman Barbarossa brothers Oruç and Arnaut Mami.

A navy, naval force, military maritime fleet, war navy, or maritime force is the branch of a state's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields.

The strategic offensive role of a navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of a navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broadly divided between riverine and littoral applications (brown-water navy), open-ocean applications (blue-water navy), and something in between (green-water navy), although these distinctions are more about strategic scope than tactical or operational division.

Aircraft hijacking (also known as airplane hijacking, skyjacking, plane hijacking, plane jacking, air robbery, air piracy, or aircraft piracy, with the last term used within the special aircraft jurisdiction of the United States) is the unlawful seizure of an aircraft by an individual or a group. Dating from the earliest of hijackings, most cases involve the pilot being forced to fly according to the hijacker's demands. There have also been incidents where the hijackers have overpowered the flight crew, made unauthorized entry into the cockpit and flown them into buildings—most notably in the September 11 attacks—and in some cases, planes have been hijacked by the official pilot or co-pilot, such as with Ethiopian Airlines Flight 702.

Unlike carjacking or sea piracy, an aircraft hijacking is not usually committed for robbery or theft. Individuals driven by personal gain often divert planes to destinations where they are not planning to go themselves. Some hijackers intend to use passengers or crew as hostages, either for monetary ransom or for some political or administrative concession by authorities. Various motives have driven such occurrences, such as demanding the release of certain high-profile individuals or for the right of political asylum (notably Ethiopian Airlines Flight 961), but sometimes a hijacking may have been affected by a failed private life or financial distress, as in the case of Aarno Lamminparras in Finnair Flight 405. Hijackings involving hostages have produced violent confrontations between hijackers and the authorities, during negotiation and settlement. In several cases – most famously Air France Flight 139, Lufthansa Flight 181, and Air France Flight 8969 – the hijackers were not satisfied and showed no inclination to surrender, resulting in the deployment of counterterrorist police tactical units or special forces to rescue the passengers.

A false flag operation is an act committed with the intent of disguising the actual source of responsibility and pinning blame on another party. The term "false flag" originated in the 16th century as an expression meaning an intentional misrepresentation of someone's allegiance. The term was originally used to describe a ruse in naval warfare whereby a vessel flew the flag of a neutral or enemy country to hide its true identity. The tactic was initially used by pirates and privateers to deceive other ships into allowing them to move closer before attacking them. It later was deemed an acceptable practice during naval warfare according to international maritime laws, provided the attacking vessel displayed its true flag before commencing an attack.

The term today extends to include countries that organize attacks on themselves and make the attacks appear to be by enemy nations or terrorists, thus giving the nation that was supposedly attacked a pretext for domestic repression or foreign military aggression (as well as to engender sympathy). Similarly deceptive activities carried out during peacetime by individuals or nongovernmental organizations have been called false-flag operations, but the more common legal term is a "frameup", "stitch up", or "setup".
