After conflict, states occasionally succeed in reconciling with former adversaries. When they do, they do so in different ways. Some grudgingly sign a treaty to signal the end of a conflict. Others provide for not only reparations and compensations but also economic assistance as material evidence of reconciliation. Yet others offer apologies, official and unofficial, and engage their former adversaries in reflective dialog that transforms their relationship from enmity to amity. Is there a way to systemically organize different ways in which states reconcile? Can different types of reconciliation be identified? If so, what explains the types? We address these questions in this article. Based on our survey of war terminations in the post-World War II period, we identify four different types of reconciliation that former injurious states have made with their victim states – procedural, material, ideational, and substantial. We hypothesize that their choice of a reconciliation type can be explained in terms of a configuration of national interest and national reflection. In this article, we engage in a structured comparative analysis of the cases of reconciliation between France-Algeria, Japan-Korea, Germany-Czechoslovakia/Czech Republic, and Germany-Poland – that we argue closely resemble the four ideal types – and demonstrate that our hypotheses are confirmed. We conclude with a consideration of how likely it is for ideational and material reconciliation to develop into substantial reconciliation
