Jamaah Ansharut Daulah (JAD, Indonesian: جماعة أنشاروت دوله, lit.
Islamic Defenders Front (FPI), at its existence, 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.
Zainal Anshori, then National Leader of JAD, was head of FPI Lamongan of 2005–2008 period.
Prior the appointment, he was renowned as Islamic activist that moved independently to commit sweepings with his group, against undesirables and un-Islamic elements.
However, all changed when the branch involved with Jamaah Islamiyah, and subsequent contact with Aman Abdurrahman [id], an Islamic militant, along with the death of Dr. Azahari and Noordin M. Top.
On 10 August 2008, Muhammad Rizieq Shihab personally warned FPI Lamongan, following a brutal attack against an alcohol seller during a sweeping.
[13][14] In his confession made 9 February 2021, Zainal Anshori stated that the seed of what will be JAD had come into being during this period.
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.
