A concise history of Northern Ireland through its pivotal moments. Since the United Kingdom's withdrawal from the European Union, the constitutional position of Northern Ireland within the Union has endured an unusual level of attention. Northern Ireland and the UK Constitution leads us through its pivotal moments: the 1920-72 Unionist-led governments, the following thirty years of bitter conflicts, the 1998 Belfast/Good Friday Agreement, and the 2016 referendum on the United Kingdom's membership in the European Union. Considering each of the moments in the broader setting of UK constitutional norms and narratives, she addresses the exceptional constitutional characteristics of Northern Ireland and the ways in which these have often resulted in "blindspot" analyses of the Union. This short book also considers the implications of Brexit and the constitutional impacts and shifts it has brought to Northern Ireland and discusses the possible constitutional repercussions.
