The group in its original incarnation operated openly in the United Kingdom from 14 January 1986 until the British Government announced an intention ban in August 2005. The group preemptively "disbanded" itself in 2005 to avoid this, two aliases used by the group were proscribed by the British Home Secretary under the Terrorism Act 2006; "Al Ghurabaa" and "The Saviour Sect". Further proscriptions followed with the Terrorism Act 2000 where "Islam4UK" was proscribed as an "Al-Muhajiroun" alias and "Muslims Against Crusades" followed in 2011. More recent aliases have included "Need4Khilafah" and the "Shariah Project", proscribed in 2014, just before prominent members, including Anjem Choudary were sent to prison (they have subsequently been released).
