In the second half of the nineteenth century, most European nations experienced a period of state-sponsored anti-Catholic legislation that has come to be known by the German term Kulturkampf. The question that this article seeks to address is whether or not the United Kingdom, and specifically Ireland, can be said to have experienced such a phenomenon. By examining the case of Robert O'Keeffe, a Roman Catholic parish priest who sued the cardinal archbishop of Dublin in the civil courts, it is possible to determine both whether Britain experienced a Kulturkampf, and to offer some suggestions as to why the United Kingdom appears to have been different in this regard from its European neighbours.
