Winner of the 2022 CHOICE Outstanding Academic TitlesThe first woman elected to lead a major Western power and the longest serving British prime minister for 150 years, Margaret Thatcher is arguably one the most dominant and divisive forces in 20th-century British politics. Yet there has been no overarching exploration of the development of Thatcher's views towards Northern Ireland from her appointment as Conservative Party leader in 1975 until her forced retirement in 1990. In this original and much-needed study, Stephen Kelly rectifies this. From Thatcher's 'no surrender' attitude to the Republican hunger strikes to her nurturing role in the early stages of the Northern Ireland peace process, Kelly traces the evolutionary and sometimes contradictory nature of Thatcher's approach to Northern Ireland. In doing so, this book reflects afresh on the political relationship between Britain and Ireland in the late-20th century. An engaging and nuanced analysis of previously neglected archival and reported sources, Margaret Thatcher, the Conservative Party and the Northern Ireland Conflict, 1975-1990 is a vital resource for those interested in Thatcherism, Anglo-Irish relations, and 20th-century British political history more broadly.
