Piracy is robbery committed at sea, or sometimes on shore, without a commission from a sovereign nation (as distinct from privateering, robbery with sovereign commission).

Etymology

Maritime piracy, according to the United Nations Convention on the Law of the Sea (UNCLOS) of 1982, consists of any criminal acts of violence, detention, or depredation committed for private ends by the crew or the passengers of a private ship or aircraft that is directed on the high seas against another ship, aircraft, or against persons or property on board a ship or aircraft. Piracy can also be committed against a ship, aircraft, persons, or property in a place outside the jurisdiction of any state.

The English "pirate" is derived from the Latin term pirata, and ultimately from Greek peira (πεῖρα) "attempt, experience", implicitly "to find luck on the sea". The word is also cognate to peril. In 17th and 18th century sources the word is often rendered "pyrate". However, the term does not exclusively relate to robbery committed at sea, as other similar origins have a broader definition 1.

Ancient origins

On one voyage across the Aegean Sea in 75 BC, Julius Caesar was kidnapped by Cilician pirates and held prisoner in the Dodecanese islet of Pharmacusa. He maintained an attitude of superiority throughout his captivity. When the pirates decided to demand a ransom of twenty talents of gold, Caesar is said to have insisted that he was worth at least fifty, and the pirates indeed raised the ransom to fifty talents. After the ransom was paid, Caesar raised a fleet, pursued and captured the pirates, and had them put to death. The Senate finally invested Pompey with powers to deal with piracy in 67 BC (the Lex Gabinia), and Pompey after three months of naval warfare managed to suppress the threat. In the 3rd century, pirate attacks on Olympos (city in Anatolia) brought impoverishment. Among some of the most famous ancient pirateering peoples were the Illyrians, populating the western Balkan peninsula. Constantly raiding the Adriatic Sea, the Illyrians caused many conflicts with the Roman Republic. It was not until 68 BC that the Romans finally conquered Illyria and made it a province, ending their threat.

As early as 258 AD, the Gothic-Herulic fleet ravaged towns on the coasts of the Black Sea and Sea of Marmara. The Aegean coast suffered similar attacks a few years later. In 264, the Goths reached Galatia and Cappadocia, and Gothic pirates landed on Cyprus and Crete. In the process, the Goths seized enormous booty and took thousands into captivity.
