Gush Emunim
In 1976, Gush Emunim founded the settlement-building arm Amana, which soon became independent and is still active. In 1979-80, a group of members from Gush Emunim radicalised and formed the Jewish Underground. This organization conducted several terror attacks and plotted to blow up the Dome of the Rock. The uncovering of the terrorist organization led to a severe blow to the settler movement's reputation. Following the crisis, Gush Emunim's role as the formal umbrella organization of the settler movement was gradually taken over by the Yesha Council, although Gush Emunim never formally ceased to exist. Despite being rooted in Gush Emunim, the Yesha Council is considered more practical and pragmatic than its predecessor. The Yesha Council, in its role as the political umbrella organization, and Amana, as the executive, settler-building branch, nowadays form the two main institutions of the settler movement.
