Yemen is in the grip of its most severe crisis in years. The struggle for power in the Arab world’s poorest but strategically vital nation has serious implications for the region and beyond. In this invaluable analysis, Helen Lackner uncovers the social and political conflicts that threaten the very survival of the state and its people. ‘A superb book written by an outstanding author whose knowledge of Yemen is unparalleled… an indispensable guide.’ Dr Noel Brehony CMG, former Chairman British-Yemeni Society; ‘An outstanding book that provides answers to all of the questions raised by Yemen’s many crises since 2011. Written with compassion and insight.’ Eugene Rogan, University of Oxford; ‘An eminently valuable account of Yemen’s modern history and current travails.’ Roger Owen, Harvard University
