Greek mafia

History

Organized criminal activity in Greece predates the modern use of the term "Greek Mafia". Historical studies identify banditry, smuggling and other forms of illicit economic activity as important antecedents during the 19th and early 20th centuries, though these should not be equated directly with modern organized crime. During the second half of the 20th century, organized criminal activity increasingly became associated with Greece's expanding urban centers, particularly Athens.

From the 1970s and 1980s onward, criminal networks became increasingly visible around nightclubs, bars and other parts of the entertainment economy, with protection racketeering becoming one of the characteristic activities. Greek organized-crime networks generally did not develop according to a single hierarchical model comparable to the traditional Sicilian Mafia; instead, they tended to consist of relatively small groups, personal networks, family connections and shifting alliances.

The 1990s represented an important period in the institutional recognition of organized crime in Greece, as the country's geographical position between southeastern Europe, the eastern Mediterranean and western Europe made it an important location for trafficking and smuggling routes. During this period, public and political discussion frequently focused on the participation of foreign nationals in organized crime, though later research emphasized that Greek nationals and domestic criminal networks also played an important role.

By the end of the 1990s, Greek organized crime was increasingly connected to international criminal markets. During the 2000s, organized criminal activity in Greece became increasingly diversified, with criminal groups involved in drug trafficking, smuggling, illegal gambling, fraud and money laundering.

The 2020s

By the mid-2020s, organized crime in Greece had become deeply international. In April 2024, Eurojust helped Greek and Serbian authorities break up a drug-trafficking ring tied to the 2020 murders of four rival gang members in Greece. Ten suspects were arrested across Greece, Serbia, and Spain. The investigation revealed a criminal group based in the Western Balkans that focused on large-scale drug smuggling.

A split within that group created a rival faction in Greece, which then sparked a wave of killings and attempted killings across Europe. This case showed how the line between local and international crime in Greece had blurred. Cigarette smuggling and fuel-related offenses had also become major battlegrounds for competing networks. In January 2024, Vangelis Zambounis, a well-known figure in the Greek underworld, was shot dead in Athens.

The killing was linked to a power struggle over cigarette smuggling and control of the nighttime economy. By July 2026, nine defendants had been ordered to stand trial for his murder. In April 2025, Giorgos Moschouris was killed in Halandri, a northern suburb of Athens. Police arrested suspects and treated the case as part of an ongoing conflict between organized crime groups.

According to Greek police sources, Moschouris had been involved in protection rackets and other illegal activities. In May 2026, authorities announced the arrest of three suspects in connection with that killing, and another suspect already in custody was also implicated. The case was investigated alongside several other murders and attempted murders linked to internal gang conflicts. Recent probes have highlighted criminal networks made up of people from various national backgrounds, including Greek nationals originally from the former Soviet Union, as well as Georgian, Russian, and Ukrainian nationals.

Criminal activities

Organized criminal groups operating in Greece have been associated with a wide range of activities, including extortion and protection racketeering, drug trafficking, cigarette and tobacco smuggling, fuel smuggling and related fraud, money laundering, illegal gambling, human trafficking and sexual exploitation, migrant smuggling, weapons trafficking, fraud and financial crime, illegal lending and usury, organized theft, arson and attacks involving explosives, and targeted killings and attempted killings.

Drug trafficking remains one of the major criminal markets affecting Greece; Greek authorities regularly investigate networks involved in the importation, transportation and distribution of cocaine, cannabis and other controlled substances. In December 2024, the Hellenic Police announced the dismantling of a transnational drug-trafficking network consisting of four criminal organizations, resulting in 28 arrests and the seizure of substantial quantities of drugs, with Greek authorities estimating that the network had trafficked more than 1.5 tonnes of cannabis and more than 43 kilograms of cocaine.

Cigarette and tobacco smuggling have been repeatedly identified as important sources of criminal revenue, with recent Greek investigations linking tobacco smuggling with money laundering, shell companies, extortion and violent disputes between criminal organizations. Protection racketeering is historically one of the activities most closely associated with the expression "Greek Mafia"; criminal groups have targeted nightclubs, restaurants, bars, gambling establishments and other businesses, demanding regular payments in exchange for protection or threatening violence against businesses that refuse.

Outside Greece

Greek organized crime in Australia is not a single unified group but a collection of individuals and networks of Greek, Greek-Australian, or Greek-Cypriot heritage. These figures have been part of the wider Australian underworld, mainly active in Melbourne and Sydney, and have sometimes kept ties with criminal groups abroad. In Sydney, one well-known figure was John Macris, who had links to the city's nightlife and criminal circles. In 2012, members of the Ibrahim family were found not guilty of plotting to kill him.

Macris later relocated to Greece, where he was fatally shot in Athens in November 2018. Another Sydney figure was James Dalamangas, wanted for the 1999 murder of George Giannopoulos at a Belmore nightclub. Police believed he escaped to Greece after the killing and stayed there for years, highlighting the cross-border connections between Australian and Greek crime. In Melbourne, Greek-Australian and Greek-Cypriot individuals were part of the city's gangland scene.

Evangelos Goussis, also called "Ange," was convicted for the murder of Lewis Caine and later for killing underworld figure Lewis Moran. He received a life sentence with a 30-year minimum term. Another Melbourne figure was Andrew Veniamin, known as "Benji," a hitman involved in the city's gangland conflicts. In March 2004, he was shot dead during a confrontation with Mick Gatto at a Carlton restaurant. Gatto was later acquitted after a jury accepted his self-defense claim.
