Book excerpt: Published in 1999, this text examines domestic wars, looking at inter-state relations only in as far as they are directly relevant to understand such wars. The book aims to indicate how intra-state war differs from the inter-state war, and focuses primarily on such domestic armed conflicts that at least have significant ethnonational components. The book assesses how heterogeneous a category "ethnic conflict" is in terms of causes and consequences, and gauges the complex interplay between class, regionalism and ethnicity. It is not limited to description and causal analysis, but also attempts to assess suggestions as to what types of actors may contribute in what ways to avoiding ethnonational mobilization/polarization, avoiding militarization of manifest conflicts, and de-escalating militarized conflicts by looking for tenable generalizations on what types of approaches are fruitful in bringing about de-escalation, ceasefires, political compromises, peaceful division or peaceful integration, reconciliation.
