Using a vast range of primary sources, this substantial and important volume provides a comprehensive analysis of the division and near-collapse of Habsburg authority during the 1550s. The principal episodes of this period (the death of Charles V, the accession of Philip II, and the latter's marriage to Mary Tudor) are well known in outline, but Dr Rodriguez-Salgado provides much that is new and original, both on the internal history of Spain, and on the highly complex diplomacy of the period. Why did Charles V and Philip I go to war against France, and Papacy and Islam, and how did the multinational empire survive the huge financial demands such wars placed upon it? Spanish relations with England and France are examined in detail, and The Changing Face of Empire does a great deal to illuminate the breakdown in relations with the Netherlands that was to culminate in the Dutch Revolt.
