Whether in a global political context or within society, irreconcilability seems to be the hallmark of our present times. This explains the growing interest in reconciliation processes. Since the 1990s, ‘reconciliation’ has been an established field of research in political science. Historians, however, have explored this field only to a limited extent, although the topic should be an obvious one for them, as the call for reconciliation always relates to the past. Political science analyses of reconciliation or irreconcilability usually concentrate on political explanations. They pay little attention to social or economic and even less to cultural factors. This is where historical research can contribute to a better understanding. The aim of the lecture is to shed light on the potential of historical reconciliation research, with a particular focus on the entangled history of Germany and Great Britain.
