This book illuminates, in the form of a clear, well-paced and student-friendly analytical narrative,  the functioning of the European states system in its heyday, the crucial century between the  defeat of Napoleon in 1814 and the outbreak of the First World War just one hundred years later. 

 In this substantially revised and expanded version of the text, the author has included the results of the latest research, a body of additional information and a number of carefully designed maps that will make the subject even more accessible to readers.
