• Family of Veneto Mala del Brenta, 1960s

The criminal organization's structure is believed to be based upon some elements of the Cosa Nostra and Camorra model. It is considered by the Italian government and Prefecture of Venice as including all the characteristics of Article 416 bis-cp, the legislative definition of a mafia type organization with Mafia (Cosa Nostra, 'Ndrangheta, Camorra) affiliations within Italy. It has been referred to by several different names including: Mafia del Brenta, Malavita del Brenta, Mala or Mafia del Piovese.

In the 1960s and 1970s a number of high ranking members of the Sicilian Mafia were sent in solitary confinement in various provincial towns in the Veneto, mostly around the cities of Vicenza, Padua and Venice, in an attempt to isolate powerful sicilian ringleaders from other members in the Mafia. The most notable Sicilian mafiosi included: Salvatore Contorno, Gaetano Fidanzati, Antonino Duca and Gaetano and Salvatore Badalamenti, and Giuseppe Madonia. Veneti malavitosi, or underworld figures and bandits from the Veneto, learned from these Sicilians the necessary means for organizing themselves and taking the reins of control from the successive two decades. What started as a small gang of criminals controlling racketeering along the Riviera del Brenta between Padua and Venice, became an international syndicate under the "boss" Felice Maniero.

Before the arrival of these high calibre sicilian mobsters, Veneto's crime problem was restricted to various disorganized gangs operating throughout the region. In the 1980s, just before the emergence of the Mala del Brenta there were already a few organized crime syndicates that would later be incorporated under the central authority of the Mala del Brenta. These organizations included:

• "Clan Giostrai". These were various affiliated groups of nomad criminals mostly from the provinces of Vicenza, Padova and Venice, of whom a number had a relation to the carnival fair businesses, and where involved in bank heists and robberies, drug trade and more notably kidnapping for ransom.
• The "Mestrini" group, based in Mestre, on the immediate Venetian mainland, a powerful group with strong ties to the Mala del Brenta, their most lucrative trade was drug trafficking, but the group was involved in a vast array of criminal enterprises. Most notably the ownership of many abusive water taxis that would bring foreign tourists to shops and hotels in Venice that were owned by the clans associates. The "zoccolo duro" or top capos of the organization were: Gino Causin, Gilberto "Lolli" Boatto, Paolo Tenderini, Roberto "Paja" Paggiarin and Paolo Pattarello.
• The "Veneziani", the old criminal underworld of Venice, engaged in the same activities of the "Mestrini", the group was headed by the Rizzi brothers and Giancarlo Millo, nicknamed "The Martian".
• The San Donà di Piave cartel, under the leadership of Silvano Maritan, nicknamed "The President", protégé of the confined Cosa Nostra boss Salvatore Contorno, the rivalry with another cartel based in the same area caused a number of violent confrontations and subsequently placed Maritan as capo of the eastern part of the province of Venice, that is until he gave up a percentage of his assets to Felice Maniero.

Maniero born in the impoverished village of Campolongo Maggiore, in the mainland province of Venice started his own crew of local gangsters, composed of family members and childhood friends that would later hold the reins of his criminal empire. While becoming a major criminal presence in the area, he was befriended by a number of prominent Sicilian mafiosi who backed him up in his vision of uniting Veneto organized crime.

Maniero's establishment subsequently controlled all criminal ventures in the region, all other organized crime groups in the region had been subjugated by the group originating from Campolongo Maggiore and backed up by the Sicilians and also members of the Camorra. All except the exponents of the "Veneziani" clan, the Rizzi brothers, were feeling menaced by the mainland syndicates under Maniero, but the other "Veneziano" capo Millo, was a personal friend of Maniero, and preferred collaborating with "Angel Face" and his allies. While dining at a restaurant, Millo was shot and killed on March 17, 1990 by the Rizzi brothers. A violent feud ensued, between the Mala del Brenta and the "Veneziani". After six months, the Rizzi brothers and an associate were treacherously murdered in an ambush disguised as a meeting to discuss peace terms. Maniero placed Giovanni Giada as head of the Mala del Brenta in the Venetian lagoon. He was now in firm control of all Veneto.

The organization has had a number of high level political connections outside Italy (Croatia and Yugoslavia, Malta, Hungary and Austria). At one point, Maniero was a personal friend of the son of the former Croatian president Franjo Tuđman and was involved in the supply of guns to Croatia, in the early 1990s.

The organization had a firm hold of nearly every criminal venture in the region, from money laundering to loansharking and extortion, but its major source of income was drug dealing; the group bought massive amount of cocaine directly from the Sicilian and Colombian Mafia, as well as heroin from Turkish drug baron Nvo Berisa, who helped a number of Venetian mobsters in hiding in Turkey including Felice Maniero and Antonio Pandolfo, the group's second in command.

Its members are exclusively native to the Veneto region, but with a number of associates operating in the region from Cosa Nostra, Camorra and it is believed from the Ndrangheta as well. It is also known that Brenta mafiosi have colluded with Stidda members on a number of occasions involving a number of fraudulent scams at a Maltese casino in 2002.

The organization was thought to be dismantled in late 1994, due to revelations that the former boss Maniero was captured by a task force of 400 policemen issued with the sole task of bringing Maniero and his associates down. After being arrested in Turin in 1993 (having previously evaded the Padua and Vicenza prisons) together with many of the top members of the syndicate.

Maniero, faced with life imprisonment, turned informant, helping the Italian police dismantle the organization he himself had created, contributing to the arrest of more than 400 of the mob's members, as well as a number of judges, policemen and local Venetian businessmen that had aligned themselves with the organization.

Although it has been revealed that Maniero continued a number of criminal activities and many of his former henchmen re-organised the Mala del Brenta to ensure survival, it is now called Nuova Mala del Brenta or Nuova Mafia Veneta and it still influences many criminal ventures in the region, ranging from robberies and bank heists to arms and drug trafficking.

In August 1996, the members of the re-instated gang, coordinated a spectacularly successful heist at the "Mirabilandia" theme park securing 350 billion lira in an attempt to get the group back on its feet after the revelations of Maniero and other turncoats

In May 2005, Francesco Tonicello a member of the old Mala del Brenta, was arrested in London after having been on the run for a number of years as one of Italy's most wanted men. A master forger, he worked under 11 aliases and fenced priceless artworks, antiques and gold for Venetian godfather "Angel Face" Maniero, as well as participating in a brutal double homicide.

In April 2005, the carabinieri killed Luigi Quatela a top member of the syndicate in Chiampo, in the province of Vicenza.

In August 2006, the massive "Ghost Dog" operation took place. Italian police arrested over 60 exponents of the criminal organization, including policemen on the group's payroll. After two years of investigation, and the precious revelations of the turncoats Stefano Galletto and Giuseppe Pastore, police delt a severe blow to the organization, arresting local gang leaders in the provinces of Venice, Padua, Vicenza and Verona, most notably Achille Pozzi, from Padua, and Giorgio Fontana from Vicenza, together with their respective henchmen.

In July 2007, the Carabinieri busted a criminal group composed of ex Mala del Brenta associates and nomad criminals from the province of Vicenza, as they were trying to form a new group made up of the older elitè members of mala del Brenta who had escaped or completed prison sentences and Vicenza and Bassano criminals engaging in drug trade and robberies. The group had been responsible for five gangland killings in the last three months, but turncoat Maich Gabrielli helped dismantle the group after witnessing the murder of 26 year old cousin Emanuele Crovi.

In August 2007, a seventeen year old Tunisian boy was kidnapped as a result of hostilities between immigrant drug dealers. Beaten and held hostage for several days in Padua's periphery, his kidnappers were two Albanians and an Italian slightly older than he was. When the Carabinieri came to liberate the hostage a gunfight ensued, with a Carabiniere getting wounded. The juvenile criminals succeeded in escaping in a car whose number plates belonged to Lucio Calabresi, a capo of the Nuova Mala del Brenta. When the Carabinieri deepened their investigation into the incident, they uncovered a series of a new alliances between the syndicate and a number of immigrant youth gangs present in the city of Padua.

In October 2007, Italian police arrested Ercole Salvan, member of the syndicate, and one of the most feared bandits of the region. Hailing from Cittadella (Padova), he had been on the run since the murder of a truck driver during a highway robbery.

In November 2007, a task force of about a hundred Italian and Spanish policemen, interrupted a steady flow of cocaine, from South America via Spain to North-Eastern Italy controlled by one of the organization's top members, the infamous Silvano Maritan, head of the San Donà di Piave cartel, already one of the head figures in the "old" mala del Brenta. After being released from prison in 2001, he took control of the drug trade in eastern Veneto, supplying cocaine in a number of discos all along the Venetian coastal resorts.

In May 2008, Italian investigators uncovered a plan to free bosses Lucio Calabresi and Mariano Magro from their prison in Vicenza. The man who intended to do this was Rafaele Vassallo, the plan was to subsequently murder a judge, two police captains, turncoat Stefano Galletto and his family, and finally Felice Maniero in a series of terrorist attacks to be carried out with explosives and rocket launchers. A warehouse full of armaments was found in Padua's industrial area, and the would-be conspirators of the plan were arrested.

In November 2008, the Carabinieri busted an unusual criminal join venture made of former Far Right and Far Left terrorists, associates of the old Milan organized crime and Nuova Mala associates, above all Fiorenzo Trincanato, once one of Felice Maniero's enforcers. This group was believed to be involved in drug trafficking in Northern Italy, controlling cocaine trade from Veneto to Liguria.
