The conceptual uncertainty when dealing with processes of integration and disintegration in Europe is striking because traditional notions of the nation-state, constitutionalism, sovereignty, and federalism do not account for emerging realities in either Western or Eastern Europe. This volume explores the complex inter-relationship between federal arrangements and their effects on integrating multi-ethnic societies in Europe, and takes stock of current debates on the effects of federalism on integration and disintegration in Eastern and Western Europe. For the first time federalism is addressed in a pan-European context and an attempt is made to look for remedies to overcome nationalism in both East and West within a federalist institutional framework.

The war in Ukraine has been fought with, among others, irregular armed groups since 2014--volunteers, paramilitaries, and mercenaries. Based on interviews in the Russian-controlled Donbas and with Ukrainian combatants, the contributions to this volume disclose various micro-dynamics of the mobilization, group formation, and fighting. Who were these fighters and who organized them? Russia has been increasingly employing mercenaries as a way to conduct undeclared, but ruthless wars beyond her borders. Ukraine's formation of irregular armed groups in 2014 was a response to the army's initially glaring inability to counter Russia's military intervention. Most of the irregular battalions acted from the beginning under governmental orders. They have never operated autonomously, but compensated for operational weaknesses of regular armed groups. The initially high power of irregular battalions derived from state support, the capabilities of commanders, social networks, and the faculties of the fighters.
