The book is extremely well written focusing clearly on the important issues of foreign policy throughout the period. The book lacks detail in a few areas - for example it does not follow an in depth study and the maps leave much to be desired. Nevertheless the book is of great use to anyone studying British history below degree level and especially useful for A-Level and AS-Level students. The book clearly examines the key issues of how far Britain's foreign and imperial policy changed during the period, how successful the policies were and questioning why Britain took part in New Imperialism. It has an excellent overall framework of events and starting in 1865 when Britain controlled 75%of the world effectively leads into the Abyssinian Campaign which follows. It pays a great deal of attention to Gladstone's Second Ministry and most of the book covers Salisbury's period of 'splendid isolation'. The biggest advantage of this book is its on going analysis of events - removing much of the narrative which plagues higher level histroy students. It emphsises the types of questions that may be faced in exams and through model answers by real students it highlights many of the traps students fall into. The book is comparable with Derrick Murphy's 'Britain 1815-1918' (Flagship History, Collins 1998)although the it is more focused on higher grade candiadates. I would recommend the book to anyone studying histroy at GCSE or above, I am an A-Level student and this book has been like a Bible to me - a necessary tool for any A-Level history student.
