The history of the JAD is still unclear, due to the secretive nature of the group. However, several small portions of its history are known currently.
2005: As part of Lamongan branch of the Islamic Defenders Front Islamic Defenders Front (FPI), at its existence was renowned for having loose coordination despite its complexity of their structure and rank. Although the networks penetrate into district and sub-district levels, they are loosely coordinated, and often there are cases of fragmentation. Among many of its branches, there was a branch renowned for its extremism, FPI
Lamongan branch (FPI Lamongan), which had a linked and strong relationship with
Dr. Azahari and
Noordin M. Top, both
Malaysian terrorist kingpin. Zainal Anshori, then National Leader of JAD, was head of FPI Lamongan of 2005–2008 period. He was appointed by
Muhammad Rizieq Shihab himself to lead FPI Lamongan. Prior the appointment, he was renowned as Islamic activist that moved independently to commit sweepings with his group, against undesirables and un-Islamic elements. After that, FPI Lamongan actively committed sweepings. However, everything changed when the branch involved with
Jamaah Islamiyah, and subsequent contact with Aman Abdurrahman
[id], an Islamic militant, along with the deaths of Dr. Azahari and Noordin M. Top. Starting from there, FPI Lamongan shifted away to
Islamic extremism. Affected with Islamic extremism ideology, FPI Lamongan used an extreme approach of imposing the Islamic doctrine of
''amr ma'ruf nahy munkar'' (enjoining good and forbidding wrong). They also often used excessive force. On 10 August 2008, Muhammad Rizieq Shihab personally warned FPI Lamongan, following a brutal attack against an
alcohol seller during a sweeping. Due to its extreme way and acts, FPI Lamongan was disavowed by central leadership of FPI on request of East Java Regional FPI around 2010. Despite that, sympathizers remained, and in 2013 the sympathizers of the disavowed branch clashed with Lamongan locals. In his confession made 9 February 2021, Zainal Anshori stated that the seed of what would become JAD had come into being during this period. The element that subsequently evolved into JAD was integrated during his leadership of FPI Lamongan on 2005. What happened to this element after FPI Lamongan being disavowed is unclear.
2014–2018: Becoming JAD and active as organization Aman Abdurrahman was recaptured by law enforcement for his involvement on training
JAT terrorists in
Jantho (
Aceh) in 2010 and assisting escape of
Dulmatin, one of the
2002 Bali bombings perpetrator with Azahari and Noordin. Soon after announcement of formation of
ISIL by
Abu Bakr Al-Baghdadi, he pledged his allegiance to him in June 2014 during his incarceration at Kembang Kuning Detention House,
Nusakambangan Island. He later drafted a concept of organization that will support ISIS in Indonesia. Sometime later Zainal Anshori and Marwan visited him. In November 2014, JAD formed followed a ''majlis ta'lim
in Batu. In that majlis ta'lim'', Aman Abdurrahman become the Spiritual Leader of the group, Marwan become the National Emir, Zainal Anshori become the Emir of East Java, others have each specific posts established. During its time as organization, JAD actively participated in various terrorism acts, notably
2016 Jakarta attacks,
2016 Samarinda church bombing,
2017 Jakarta bombings,
2018 Mako Brimob standoff, and
2018 Surabaya bombings.
2018–2026: Actions after disbandment On 21 June 2018,
Joko Widodo signed Law No. 5 of 2018, as amendment of Law No. 15 of 2003 (Law on Anti-Terrorism Acts). The law granted much sweeping powers for law enforcement to capture terrorists and suspected terrorists. With the new law, even membership of announced terrorist organization enough to capture its member. On 31 July 2018, a
South Jakarta court made a ruling. The ruling, known as South Jakarta District Court Ruling No. 809/Pid.Sus/2018/PN JKT.SEL outlawed the organization, allowing the arrest of all its members and organizers. Even after disbandment, JAD still active clandestinely. After the disbandment,
2019 Medan suicide bombing,
2020 South Daha attack, and
2021 Makassar cathedral bombing happened. Aside the attacks, Two members of the JAD were believed to have conducted the knife assault on security minister
Wiranto on 10 October 2019, which resulted in Wiranto being hospitalized. Three other people, including a policeman, were stabbed and injured. It is still difficult to weed out JAD members, due to each cell of JAD are autonomous and do not have commanding figures and chain of command. Even each cell may not know each other. Due to being autonomous and have widespread presence across the country, the multiple attacks by JAD cells may happened in nearly same time, or even triggering
domino effect which triggered with one act of one cell may happened. On 7 December 2022,
Astana Anyar bombing – at around 8:20 AM
Western Indonesia Time (
UTC+7), a
suicide bombing incident occurred at an
Indonesian National Police station in Astana Anyar district,
Bandung,
West Java. The attacker and one police officer were killed by the explosion, while 11 people were injured including 3 police officers.Identity of the perpetrator and his affiliation subsequently released by the Police 6 hours after the attack. Police General
