Direct deaths numbered in the millions (from a much lower starting point) and some parts of Germany and Europe saw their populations decreased by over 50%. Depending on how you look at it, the 30-years war was a religious war between Catholics and Protestants or war between two imperial alliances (in fact it was both). But what it wasn't was a war between modern nation states.
The 30 Years' War is often viewed as an example of the emerging consciousness of the nation-state, but the nation-state concept was not fully incarnated until the French Revolution. But nonetheless, the deaths from the 30 Years' War were mostly not military deaths:
Based on local records, military action accounted for less than 3% of civilian deaths, with the major causes being starvation (12%), bubonic plague (64%), typhus (4%), and dysentery (5%). Although regular outbreaks of disease were common for decades prior to 1618, the conflict greatly accelerated their spread, due to the influx of soldiers from foreign countries, the shifting locations of battle fronts and displacement of rural populations into already crowded cities.
Whilst famine was a major cause, disease was the most significant cause. The war simply had an unintended consequence of greatly accelerating the spread of fatal diseases.
The Punic wars, the wars of conquest waged by Rome such as Julius Caesar's conquest of Gaul, the Mongol wars of conquest by Genghis Kahn, and many other pre-modern wars were also as deadly and devastating as anything modern nation-states did. War looked pretty total if you were a civilian in Carthage when it was under siege by Rome. Or one of the Germanic or Gallic tribes completely extinguished or sold into slavery by Julius Caesar. Or in the path of Genghis Kahn and his Mongol armies. One estimate is that about 10 percent of the world's population was killed either during or immediately after the Mongol invasions, around 38–60 million people in Eurasia. That equals the total death toll from WW2 when the world's population was vastly larger and killing was mechanized rather than by sword, spear, and arrow.
I phrased what I did to refer to the period in history after the Roman Empire; but wars in the classical era and antiquity were rather different than they are now, and the ancient empires (and their wars) looked nothing at all like the modern nation-state and her wars.
