The Irish were the single largest group of immigrants to Scotland in the nineteenth and twentieth centuries, and the original settlers and their descendants have had a major impact on modern Scottish society, culture and politics. This book of original studies is the first major reassessment of the general effect of Irish immigration on Scotland since the classic works of James Handley during the 1940s. All the contributors have produced significant research in the field, and the book provides a varied and balanced insight into current historical thinking on the Irish in Scotland.
