Werner Conze (born December 11, 1910 in Amt Neuhaus, died April 1986 in Heidelberg) was a pro-Nazi German historian in Nazi Germany, who continued to work as historian in post-World War II West Germany. He was a member of the Schieder commission. He joined the NSDAP in the late 1930s. Conze's Nazi Party membership number was 5,089,796. In his final book, written in 1986, Conze portrayed Germans as "cultivators" of the "Slavonic East", which he described as "threatening German soil"; the book had the same narrative structure as his thesis from 1940.
