​This book provides a new military history of Byzantine emperor Alexios I Komnenos's campaigns in the Balkans, during the first fourteen years of his rule. While the tactics and manoeuvres Alexios used against Robert Guiscard's Normans are relatively well-known, his strategy in dealing with Pecheneg and Cuman adversaries in the region has received less attention in historical scholarship. This book provides a much-need synthesis of these three closely linked campaigns – often treated as discrete events – revealing a surprising coherence in Alexios' response, and explores the position of Byzantium's army and navy on the eve of the First Crusade. 

Contributors to this issue approach the October 1917 Russian Revolution and the experiments of the revolutionary period as events that opened new possibilities for politics that remain vital one hundred years later. The essays highlight how those events not only affected Russia and Europe but led to the emergence of a new political image of the world and a profound rethinking of Marxist traditions. This issue globalizes the 1917 revolution, emphasizing its echoes throughout the world and the parallel development of political possibilities beyond Russia. Topics include the Soviets from the revolution to the present, the impact of the revolution in Latin America, the work of the legal theorist Evgeny Pashukanis analyzed through the lens of the revolution, anarchist imaginaries, and the historicizing of communism.
