Interweaving a grand historical narrative with cutting-edge climate science and genetic discoveries, Kyle Harper traces how the fate of Rome was decided not just by emperors, soldiers, and barbarians but also by volcanic eruptions, solar cycles, climate instability, and devastating viruses and bacteria. He takes listeners from Rome's pinnacle in the second century, when the empire seemed an invincible superpower, to its unraveling by the seventh century, when Rome was politically fragmented and materially depleted.

'If Hitler fails to invade or destroy Britain, he has lost the war,' Churchill said in the summer of 1940. He was right. The Battle of Britain was a crucial turning point in the history of the Second World War. Had Britain's defences collapsed, Hitler would have dominated all of Europe and been able to turn his full attention east to the Soviet Union. The German invasion of France and the Low Countries in May 1940 was unlike any the world had ever seen. It hit with a force and aggression that no-one could counter and in just a few short weeks, all in their way crumbled. 

The histories of the first three SS corps are well known - the actions of I, II, and III (Germanic) SS-Panzerkorps and their subordinate divisions, including the Leibstandarte SS Adolf Hitler, Das Reich, Hitlerjugend, Hohenstaufen, Frundsberg, and Nordland divisions, have been thoroughly documented and publicized. Overlooked in this pantheon is another SS corps that never fought in the west or in Berlin but one that participated in many of the key battles fought on the Eastern Front during the last year of the war - the IV SS-Panzerkorps.

Written by two of the world's leading authorities on the subject, Imperial Germany and War, 1871-1918 examines the most essential components of the imperial German military system, with an emphasis on such foundational areas as theory, doctrine, institutional structures, training, and the officer corps. In the period between 1871 and 1918, rapid technological development demanded considerable adaptation and change in military doctrine and planning.
