Using different perspectives and various approaches, this collection of diagnostic texts aims at presenting all the possible faces of the contemporary Nation-State. Based on political science methodology, this volume is devoted to both theory and practice. The structure of the book is unconventional. The issues presented are extremely contextual, subject to an ongoing discussion and mostly unpredictable. From the scientific point of view, the territorial differentiation in the traditional uniform of the Nation-State is simply reconfigured and reshaped due to the new logic of internal market competition.
