Over the last few centuries the racialisation and treatment of the Irish in Britain has changed dramatically. This is due in part to the paradigm surrounding the dynamic and fluctuating relationship between the two nations. From the colonisation, subjugation and Simeonisation of the Irish people, as British subjects, during the 18th and 19th centuries; to the dichotomy created around the question for the British government: "What to do about the Irish?", arising from the formation of the Irish Free State and further aggravated by the subsequent Irish withdrawal from the Commonwealth, during the period surrounding the formation of the Irish Republic in 1949 Subsequently, Irish people living in Britain were now once again perceived as “white” and carelessly assimilated through “forced inclusion,” into a newly constructed and imagined homogeneous British society resulting from the aftermath of WWW II (Hickmann 1998). This article aims, through the use of the historical element of the Sociological Imagination, to examine the impact of racialisation on Irish ethnic communities living in Britain. First, the essay will define and elaborate the concepts of “race” and “racialization” and the relevance of this concept to ethnic groups. The contribution will then continue by examining the mechanisms through which the Irish have become radicalized, paying particular attention to the type of characteristics attributed to the Irish over the years. The essay will then elaborate on the findings of sociological research conducted on the impact of racialisation on British residents of Irish ethnic origin and their experiences through manifestations of anti-Irish racism at institutional and personal levels.... .middle of paper ... debased and marginalized, despite their newly received 'White' status. Evidence of this can be seen in the institutionally uncontrolled signage that adorned some establishments in 1960s Britain, "No Dogs, No Blacks and No Irish". According to Hickman "there is clear evidence that Irish people living in Britain have experienced more disease, worse housing and more unemployment than can be explained by their demographic and socioeconomic status alone". This is further compounded by statistics showing that “Irish men are the only migrant group whose mortality is higher in Britain than in their country of origin” (Hickman 1998). This is further strengthened when the mortality rates of second generation Irish men and women living in Britain are examined, revealing that they are "significantly higher than those of all men and women..." living in the UK..
