Jamaah Islamiyah (JI) was established by two Indonesian clergies, Abu Bakar Ba'asyir and Abdullah Sungkar, who were evading prosecution in their country during the Soeharto period.
In Southeast Asia, the talibanization and the influence of the al-Qaeda interpretation of the jihad appear to have made their inroad in regional radical salafi movements such as the Jamaah Islamiyah (JI), Jama'ah Anshorut Tauhid (JAT), and Hizb at-Tahrlr (HT).
While extremists grouped into militant organizations such as Jamaah Islamiyah
, the usroh movement turned to politics such as Partai Keadilan Sejahtera (PKS).
Jamaah Islamiyah was formalized in 1964 as an official political party.
In 1972 Jamaah Islamiyah attempted to expand its base and mission by creating a political action group focused on Muslim demands.
In the early 1980s, however, the incubating function of Jamaah Islamiyah manifested itself in the creation in northern Lebanon of Harakat al-Tawhid (the Unitarism Movement) by Said Shaban.
In exchange Jamaah Islamiyah was able to secure three seats in the 1992 Lebanese Parliament.
Jamaah Islamiyah impressed that idea on us by citing the following Quranic verse:
The rising power of Jamaah Islamiyah inside the medical school was another critical factor in fostering my religious zealotry and that of my fellow students.
