Ronald Reagan is arguably the most successful post-war American president. A transformational leader, he is broadly credited with renewing American prosperity after the stagflation-hit 1970s, laying the foundations for Cold War victory and bringing about the shift to the right in late-twentieth century politics. In this new biography, Iwan Morgan shrewdly assesses Reagan's considerable achievements whilst also highlighting the shortcomings that were an indisputable part of his record. This edition also features a new chapter on 'Reagan in the Age of Trump'.
