This text provides a concise introduction to the events which led to the partition of Ireland, with a discussion of the subsequent development of the two Irish states which emerged from the events of 1920-1922. The author is even-handed in his treatment of the two Irish states and their politics, and deals sensitively with a very complex affair, especially when he deals with post-1968 developments. In addition to a core of chapters which explore a major theme in depth and from a number of angles, this book begins with a survey of the ways in which its theme has been treated in the past by historians and other writers; it includes a section of contemporary documents substantial enough to give an accurate flavour of the relevant theme, and it ends with a bibliography to give the guidance to further study. By these means, as well as the inexpensive format, the series aims to convey the facination of Irish history to a wider public.
