This chapter discusses key trends in the development of Irish Catholic fiction written between the 1870s and 1920s. During this period, novelists from the majority religiously-identified tradition on the island tested imagined future Irelands in their fiction. The realities to be tested were those within their own community, one dominated by a vision of a rural, small-farmer, family-aspirational, faith-sustained solidarity. Some late nineteenth-century Irish novelists cherished that solidarity, though they were not uncritical of it, while others critiqued its perceived darker side, a mean-spirited materialism and clerical authoritarianism. At the beginning of the twentieth century, a group of novelists emerged from an educated and generally urban context which valued liberal individualism. Working as priests, teachers, political activists, and journalists, they promoted an intelligentsia critique of the dominant communitarianism of the Ireland of their day. This chapter examines these developments with reference to a range of novels.
