This chapter focusses on the largely separate development of a network of Protestant nationalists in Ulster. It shows how an older generation of activists, notably Alice Milligan and Francis Joseph Bigger, sought to inculcate nationalist sentiment in younger Protestants. It traces the development of a mostly Belfast-based network, from their beginnings in various cultural nationalist groups, including the Ulster Literary Theatre, towards their adoption of a nationalist ideology, largely under the influence of the young Quaker nationalist Bulmer Hobson. This chapter also discusses the unusual development of the Independent Orange Order, whose leadership adopted a home rule ideology, and some of whom later defected to republicanism. It also assesses the efforts of Hobson and Denis McCullough to revive the Irish Republican Brotherhood in Ulster; and Hobson’s efforts, by means of the Dungannon Clubs, to promote republicanism among northern Protestants. The chapter closes with a discussion of the manner in which pressure from unionist co-religionists resulted in the breaking up of the Belfast group of Protestant nationalists, and their dispersal throughout Britain and southern Ireland.
