What was Der Jude, the journal founded by Martin Buber?

Founded by Martin Buber in 1916, Der Jude ("The Jew") was an influential monthly journal that he edited until 1924. It served as a central forum for German-reading Jewish intellectuals of the era. Within its pages, Buber advocated for the cause of Jewish-Arab cooperation to establish a binational state in Palestine, a position that was considered unpopular at the time.1
