Dr. Jander was born in Freiburg im Breisgau. During his studies of German, History, Sociology, and Political Science in the late 1970s and early 1980s in West-Berlin, he established contact with several opposition members in the GDR and followed their activities. Since then, the topic of opposition in the GDR has been one of his main research fields. Martin Jander's second important field of research is German left-wing terrorism and its international connections. In both fields of research, Jander is particularly interested in references to Antisemitism. Together with Anetta Kahane, he developed the concept of an "unfinished republic" to describe the current Federal Republic of Germany (M. Jander, A. Kahane: Gefährdungen demokratischer Kultur: Die unvollendete Republik, 2020). The republic refuses to understand itself to the full extent as an immigration society. It also refuses to see itself to the full extent as a successor society to National Socialism.
