That's another thing: Classic nationalism always included Jews out. French Jews were not really French, German Jews were not really German -- they were everywhere a separate nation, one with no territory of its own.Nationalism -- in its classic form, as it emerged in Europe in the early 19th Century -- is the idea that every nation -- defined as a group of people of shared language and culture (and, in some versions, blood kinship)
That provoked the emergence of Zionism. Some Jews got to thinking, "If we're a nation with no territory, we'd better get some!"
