“…Some of these movements, including Hizbut Tahrir Indonesia (HTI, or the Indonesian Party of Liberation), Front Pembela Islam (FPI, or Islamic Defenders Front), Majelis Mujahidin Indonesia (MMI, or the Council of Indonesian Holy Warriors), and Forum Umat Islam (FUI, or the Forum of Islamic Society), remain active today. While much has been written about HTI (Salim, 2005; Arifin, 2005; Rahmat, 2005; Fealy, 2007; Muhtadi, 2009; Ward, 2009; Ahnaf, 2009; Osman, 2010a, 2010b; Munabari, 2010), FPI (Fealy, 2004: 114–115; Hefner, 2005: 284–286; Ng, 2005; Wilson, 2006, 2008; Jahroni, 2008; Rosadi, 2008; Woodward et al, 2014), and MMI (Van Bruinessen, 2002; Fealy, 2004), FUI has so far been insufficiently studied. This is unfortunate because, like the other movements mentioned above, FUI has been actively engaging in various forms of collective action such as mass protests, public gatherings, media statements, and so forth, since it came out in the open in 2005.…”
