With unparalleled authority and dramatic detail, Charles Moore's definitive biography of Margaret Thatcher, now published in a single volume to mark the 100th anniversary of her birth, presents the whole history of the woman who transformed Britain and the world in the late twentieth century. With unique access to Thatcher's private and governmental papers and extensive interviews with her, her family, and colleagues, Moore gives readers an unsurpassed portrait of her life. From her early years and rise to power, through her transformative tenure as Prime Minister, to her final days, this biography illuminates the complexities of Thatcher's character - her determination, boldness, and the challenges she faced as a woman in a male-dominated political world. Moore brilliantly conveys her pivotal role on the world stage, her battles at home, and the dramatic events leading to her resignation. This edition combines the insights of the original three volumes, providing a comprehensive portrait of one of the most influential figures of her age, whose impact has lasted well into our own.
