Contributions to this special issue of Irish Historical Studies come under the dedicated theme of ‘Ireland and the British Empire-Commonwealth’. The papers originate from a workshop entitled ‘Ireland and empire’ that took place at the University of Leeds in March 2005. One of the key objectives behind the organisation of this workshop was to bring together specialists in British, Irish and imperial and Commonwealth history with an interest in the wide-ranging debates linked to the issue of ‘Ireland and empire’. At the workshop, the papers presented a range of topics within the context of literature and the arts; agriculture and industry; metropolitan politics and diplomacy. The overarching theme was the ‘Irish experience’ within an ‘interconnected British world’ during the nineteenth and twentieth centuries.
