Ireland through European Eyes: Western Europe, the EEC and Ireland 1945-73, edited by Mervyn O’Driscoll, Dermot Keogh and Jérȏme aan de Wiel, Cork University Press, 500 pp, £39, ISBN: 978-1859184646 On July 1st, 2013 the European Union (EU) welcomed its twenty-eighth member state, Croatia. The addition of the small Balkan state meant that fully three-quarters of the member states of the Union were now “enlargement” states, in addition to the “founding Six” member states of Belgium, France, Germany, Italy, Luxembourg and the Netherlands. Croatia’s accession may well constitute the first element of the final stage of the expansion of this unique experiment in international relations and transnational governance: southeastern (western Balkan) accessions over the next decade would add to previous rounds which progressively took the “European project” west (1973), south (1980s), north (1995) and east (2004 and 2007).
