There has been a significant, well-established if somewhat invisible Muslim population in Ireland since the 1950s. An increase in immigration during the Celtic tiger years along with the hysteria of 9/11 caused a rapid visibilization of this population. Muslims became synonymous with extremism and terrorism, but also fell victim to racist constructions emerging from the economic decline. The experience of Muslim youth since 9/11 has been well researched in the UK and Europe, however there has been little empirical work conducted with Ireland’s Muslim communities. In the literature, it is assumed that the British experience is replicated for Muslim youth in Ireland – this is not the case. This paper examines the lived experience of Irish Muslim youth given the visibilization of Islam after 9/11 and their ensuing experiences of Irishness. An analysis of ethnographic data reveals the idiosyncratic experiences of these youth growing up in the shadow of a discriminatory and Islamophobic narrative on extremism and terrorism and an evolving immigrant landscape.
