The Cambridge History of the Byzantine Empire by Jonathan Shepard (Editor)Byzantium lasted a thousand years, ruled to the end by self-styled 'emperors of the Romans'. It underwent kaleidoscopic territorial and structural changes, yet recovered repeatedly from disaster: even after the near-impregnable Constantinople fell in 1204, variant forms of the empire reconstituted themselves. The Cambridge History of the Byzantine Empire tells the story, tracing political and military events, religious controversies and economic change.
