This special issue of Historical Reflections/Réflexions Historiques derives from panel sessions for the Irish-Scottish Academic Initiative (ISAI) conference held at the University of Aberdeen in October 2009. The conference marked the tenth anniversary of the founding of Aberdeen’s Research Institute of Irish and Scottish Studies. It was also the first ISAI conference to feature panel sessions dedicated to the study of gender in Irish and Scottish history. The overarching theme of the conferenceGlobal Nations? Irish and Scottish Expansionencouraged discussion of the ways in which the history and heritage of Ireland and Scotland are interpreted and understood both within those countries and abroad. In the two panels on gender, history, and heritage we sought to interrogate past and present notions of Irish and Scottish identity through the lens of gender by bringing together speakers from universities and the heritage sector.
