The focus of diasporic humanitarian and political activism is often directed towards members of the community still residing in territory recognised as the ‘homeland’ (Bruneau 2010; Clarke 2010; Hammond 2013). Middle Eastern Christians who have migrated to the UK often due to education and employment opportunities but also in some cases due to discrimination and violence experienced in their home countries are no exception and several organisations have been set up in the UK to meet the needs of Christians in the Middle East. Using case studies of charities and lobby organisations established by Coptic, Assyrian and Iraqi Christian migrants including Iraqi Christians in Need, St Kyrel’s Trust, Assyrian Church of the East Relief Organisation and UK Copts, this paper argues that these organisations not only aim to reinforce ties with the homeland but also serve to strengthen communal identity in the UK by focusing upon the suffering of co-religionists. While organisation members may develop links with British political and ecumenical actors in order to gain publicity and support for their goals and the situation of Christians in the Middle East in general, the organisations are still primarily community-oriented concerning actions and funding. However, this approach is being challenged by the second generation who either question what they perceive as a narrow focus in terms of aims and objectives especially relating to wider UK society or else are seen by organisation leaders as being apathetic regarding more active involvement in the organisations and thus the situation of Christians in the Middle East. These intergenerational differences indicate wider tensions between the youth and older migrants relating to the role of the community in the UK and understandings of communal identity, thus potentially impacting upon the future of transnational humanitarian and political organisations run by the diaspora. This paper is based on semi-structured interviews conducted in 2014 in London and Scotland with Christians of Egyptian and Iraqi origin residing in the UK including active members of the case study organisations and is part of research conducted as part of a larger interdisciplinary project comparing Middle Eastern Christian migrant experiences in the UK, Denmark and Sweden.
