Nazi human experimentation: Nazi human experimentation was a series of medical experiments on large numbers of prisoners, including children, by Nazi Germany in its concentration camps in the early to mid 1940s, during World War II and the Holocaust.  Chief target populations included Romani, Sinti, ethnic Poles, Soviet POWs, disabled Germans, and most prominently of all, Jews from across Europe.

Historiography of the causes of World War I: Historians writing about the origins of World War I have differed over the relative emphasis they place upon the factors involved.  Changes in historical arguments over time are in part related to the delayed availability of classified historical archives.  The deepest distinction among historians remains between those who focus on the actions of Germany and Austria-Hungary as key and those who focus on a wider group of actors.  Those historians such as Fritz Fischer who believe that Germany deliberately planned a European war, once a widespread view, are now in a small minority.  The main distinction is now between those who believe that a war between the "Great Powers" was ultimately unplanned but still caused principally by Germany and Austria-Hungary taking risks, and those who believe that either all or some of the other powers, namely Russia, France, Serbia and Great Britain, played a more significant role in risking war than had been traditionally suggested.
