Maritime Piracy, Past and Present
Maritime piracy is an unlawful act of violence or detention committed for private ends by one ship against another on the high seas.
Maritime piracy is an unlawful act of violence or detention committed for private ends by one ship against another on the high seas. The definition comes from Article 101 of the UN Convention on the Law of the Sea (UNCLOS).[1] The International Maritime Bureau (IMB) counted 51 incidents worldwide in the first nine months of 2026, the lowest nine-month total since 1992, while Somali pirates held 94% of the crew taken hostage in that period.[2] Piracy's recorded history begins in the Mediterranean, and it has tended to grow under the same conditions: more trade at sea and weak authority on shore.
Rome and the Cilician Pirates
The Seleucid empire policed the eastern Mediterranean in the 2nd century BC. After about 150 BC it began to break up and control of the sea went with it. At the same time Rome's plantations wanted slaves, and pirates supplied that market. Captives were sold on Delos, where 10,000 people are said to have been sold in a single day. The pirates' main base became western Cilicia, on what is now the south coast of Turkey.[3]
Their most famous captive was the young Julius Caesar. In the account that goes back to Plutarch, he was seized around 75 BC on the way to Rhodes and held on the Aegean island of Pharmacusa. The pirates asked 20 talents, he told them he was worth more and raised it to 50, and once free he gathered ships, caught them and had them crucified. Livius.org describes two separate captures and gives the first ransom as 25 talents, and historians differ on the details.[3][4]
Rome's first efforts failed. A fleet sent in 104 BC achieved nothing, and in 74 BC Marcus Antonius lost to the Cretan pirates. When the pirates threatened Rome's grain supply, the People's Assembly passed the Lex Gabinia in 67 BC over the Senate's objections. Pompey received 20 legions, 500 ships and authority up to 75 km inland. He split the Mediterranean into thirteen zones, cleared the west in 40 days and took the Cilician strongholds in three months. He resettled the defeated in inland towns as farmers in place of executing them. Grain prices soon returned to normal.[3]
Barbary Corsairs and Licensed Raiders
In later centuries who counted as a pirate depended on where you stood. On the North African coast, the Ottoman seaman Kemal Reis moved to the Maghreb around 1487, Oruç Reis took Algiers in 1516, and his brother Hayreddin Barbarossa rose to command the Ottoman fleet. From 1559 Algiers, Tunis and Tripoli were Ottoman on paper and in practice autonomous regimes living off prizes. The corsairs attacked merchant ships and raided European coasts for the slave markets. In June 1631 Murat Reis's men emptied the Irish village of Baltimore. The historian Robert Davis estimates as many as 1.25 million captives between 1530 and 1780, a figure others dispute.[5]
Europeans had put the same trade on paper. A captain with a letter of marque from his government was no pirate, for the ship and period named in it, but part of the war. Francis Drake raided Spanish ships and ports, and the Dutchman Piet Hein captured a Spanish treasure fleet. Ending all this took force. The United States founded its navy in 1794 partly because of the Barbary threat and fought two wars between 1801 and 1815. An Anglo-Dutch fleet bombarded Algiers in 1816 and France took the city in 1830. The major powers abolished letters of marque among themselves in the Declaration of Paris of 1856, which the United States did not sign.[5][6]
The Law of Piracy
The present framework is UNCLOS of 1982. Under it, piracy is committed for private ends, from one ship against another, on the high seas or in a place outside any state's jurisdiction. Article 105 lets any state seize a pirate ship there and try those aboard in its own courts, and Article 110 lets a warship board a ship suspected of piracy.[1] The same act in a state's territorial waters is "armed robbery against ships" and is a matter for the coastal state, as the maritime law article explains. IMB figures count both together, which is why most of what gets called piracy is night-time theft from anchored ships.[2]
Political acts fell outside the definition. The hijacking of the cruise ship Achille Lauro in 1985 showed the gap. Austria, Egypt and Italy proposed a treaty at IMO, and the SUA Convention was signed in Rome on 10 March 1988 and came into force on 1 March 1992.[7] Around the turn of the century the weight of incidents lay in the Strait of Malacca. In 2004 there were 325 reported attacks worldwide, 93 of them in Indonesian waters. Lloyd's underwriters listed the strait as a high war-risk area, Indonesia, Malaysia, Singapore and Thailand stepped up joint patrols, and Lloyd's lifted the listing in 2006.[8]
Somalia: From Fishermen to Ransom Business
Modern piracy's most visible years came off Somalia. The central government collapsed in 1991, the navy disbanded and the coast was left undefended. Foreign trawlers fished illegally and coastal communities complained of waste being dumped. Fishermen armed themselves, started seizing boats for ransom and called themselves a people's coastguard. It soon became a business in its own right. In 2008 there were 111 attacks and 42 successful hijackings, with ransom income estimated at $80 million.[9]
The seizure of MV Faina, a ro-ro loaded with tanks, in September 2008 made it a world story. UN Security Council Resolution 1838 of 5 October 2008 called on countries to use military force. The EU launched Operation Atalanta in December 2008 and Combined Maritime Forces set up CTF 151 in January 2009.[9][10] The pirates meanwhile moved further out, using mother ships to go from the Gulf of Aden deep into the Indian Ocean.
Sirius Star
Sirius Star was a 332-metre VLCC owned by Vela International, a Saudi Aramco subsidiary, carrying about 2 million barrels of crude from Saudi Arabia to the United States by way of the Cape. She was hijacked at about 10:00 on 15 November 2008, some 450 nautical miles off the Kenyan coast. Of her 26 crew, 19 were Filipino. She was taken to an anchorage off Harardhere in Somalia.[11]
On 20 November the pirates demanded $25 million with a ten-day deadline, and by the 24th they had come down to $15 million. Negotiations went on for about two months. On 9 January 2009 a small plane parachuted $3 million onto the ship, she was released the same day and sailed to Fujairah in the UAE, where the crew changed. Five pirates drowned when their boat overturned on the way home with their share, and one body washed ashore with $153,000 on it.[11]
Maersk Alabama
Maersk Alabama was sailing from Salalah in Oman via Djibouti to Mombasa, partly loaded with food aid, with 23 crew who had drilled against piracy the day before. On 8 April 2009 four armed pirates attacked from the fishing vessel Win Far 161. Chief Engineer Mike Perry took 14 crew to a secure room. He and an engineer swung the rudder and swamped the pirates' skiff, but they got aboard anyway. Perry shut down the ship's systems and she went dark. The pirates seized Captain Richard Phillips but could not control the ship, and in the engine room Perry captured their leader, Abduwali Muse.[12]
The pirates left in a lifeboat with Phillips and $30,000 from the safe. USS Bainbridge and USS Halyburton arrived on the morning of the 9th. The standoff lasted three days, and talks broke down on the 11th when a pirate fired at Halyburton. On 12 April Muse went aboard Bainbridge to negotiate. Commander Frank Castellano gave the order to fire on reports that a pirate was aiming at Phillips, and SEAL snipers on the fantail killed the three men in the lifeboat. Phillips was unhurt. Muse got 33 years and 9 months in an American prison.[12]
The Decline
Attacks peaked in 2011, when the IMB counted 439 incidents worldwide and 237 linked to Somalia.[13] Successful hijackings had already dropped from 49 in 2010 to 28, because best management practices (BMP), armed guards and naval patrols were starting to work. In 2012 Somali attempts fell to 75 and hijackings to 14. In 2013 nine ships were attacked and none taken. The Indian Ocean High Risk Area was lifted in January 2023.[9][13]
The Gulf of Guinea and the Mozart Attack
As Somalia quietened, the weight shifted to West Africa. Gulf of Guinea pirates came from Nigeria's Niger Delta, which produces most of the country's oil and lives with poverty and pollution. Groups that once stole cargo and siphoned oil turned to kidnapping crew, because some companies paid large ransoms, and took hostages into the delta's swampy creeks. Here the target was people, and ships were not held for months as in Somalia. In 2020, 130 seafarers were kidnapped in this gulf in 22 incidents, and only five elsewhere in the world.[14]
The Liberian-flagged container ship Mozart, managed by Boden Denizcilik of Istanbul, was on her way from Lagos to Cape Town in January 2021 with a largely Turkish crew. On the morning of 23 January pirates boarded her about 100 nautical miles off São Tomé. The crew locked themselves in the citadel. The pirates disabled most of the ship's systems and after about five hours forced their way in, possibly with explosives. An Azerbaijani engineer was shot in the stomach and died. They took 15 Turkish seafarers off in their boats, and the three left behind sailed the ship to Port-Gentil in Gabon the next day.[15][16][17]
Captain Mustafa Kaya and the others were taken to a forest in Nigeria. He said afterwards that armed men were always around them. They suffered no physical violence but were told during the negotiations that they would be killed if the company did not pay. The pirates first contacted the owners on 28 January. The seafarers were freed in Nigeria on 12 February and landed at Istanbul Airport on the 14th. Levent Karsan of Boden said the kidnapping was not political, and the company did not say whether a ransom had been paid.[15][17] The case also showed how tangled the law can get: an attack on the high seas, a Liberian flag, Turkish captives, an Azerbaijani victim, and a release in Nigeria. Since flag state, victims' countries and capturing navy can all differ, prosecution is as hard as capture.
Somalia Returns and the Honour 25
After the Gaza war began, navies turned to the Red Sea and a gap opened in the Indian Ocean. In December 2023, by the IMB's account, came the first successful hijacking of a cargo ship in six years. The Indian Navy retook the bulk carrier involved, Ruen, about 500 km out on 17 March 2024, and 35 pirates were taken to Mumbai for trial.[9]
2026 has been harsher. The Palau-flagged product tanker Honour 25, with 18,500 barrels of oil and 17 crew, 10 of them Pakistani, was hijacked off Puntland on 21 April. After more than five months Puntland's maritime police raided her on 29 September. Puntland officials say the pirates killed five seafarers before the operation: three Pakistanis, one Myanmar national and one Indian. Four were injured and 16 suspects captured, a figure another report puts at 21. These are the first deaths directly attributed to Somali pirates in more than a decade.[18]
The Picture Today
Of the 51 incidents in the first nine months of 2026, 36 were boardings, 8 hijackings, 4 firings and 3 attempts, down from 116 incidents a year earlier. All eight hijackings were Somali. The number of crew directly affected rose from 72 to 105: 90 hostages, 6 injured and 5 killed.[2][19][20]
Most of the fall came from the Singapore Strait, down from 73 to 13, though every vessel targeted there was boarded and guns or knives appeared in over 69% of cases. In the Philippines, 9 ships were boarded at the Manila and Batangas anchorages and two crew were taken hostage, where a year earlier there had been none. The Gulf of Guinea had just 2 incidents, none from July to September.[2][19] IMB director Michael Howlett says ships fully following BMP keep preventing hijackings, even once pirates are on deck.[2][19]
In 86% of incidents the perpetrators reached the ship, mostly at night, at anchor or at low speed.[20] For a ship waiting at anchor in port, watchkeeping, lighting and door control remain the basics. In high-risk areas a citadel, fire hoses, a security team and P&I club warnings go into the voyage plan.
Frequently asked questions
What is maritime piracy?
An unlawful act of violence or detention committed for private ends by one ship against another on the high seas.
Where is piracy most common today?
By IMB data for January to September 2026 the most dangerous area is off Somalia. The highest counts were in the Singapore Strait (13) and at Philippine anchorages (9).
What is the difference between piracy and armed robbery at sea?
Piracy happens on the high seas or outside any state's jurisdiction, where any state may act. In territorial waters the same act is armed robbery and is for the coastal state to deal with.
