This book addresses key aspects relating to the use of international sanctions by assembling contributions from different fields of expertise with a view to providing readers with an interdisciplinary perspective. Unilateral or plurilateral restrictive measures, commonly referred to as “sanctions”, by States or regional organizations have been acquiring an enormous practical importance in the last decades, leading also to the institution of a European Union’s sanctioning mechanism of its own.

In addition to that, the war in Ukraine, triggered by the Russian aggression, has given them an unprecedented visibility, including in the mainstream media. The matter nevertheless remains particularly complex, given its diverse implications from a legal as well as from an economic-financial point of view, and not least in a political perspective.

This book follows up the workshop that was held at the University of Florence on 9-10 December 2021 and collects original contributions from promising or acclaimed, leading experts on sanctions. Each part of the book is devoted to three main themes: legality and legitimacy; extraterritorial implications; and effectiveness.

These parts consist of a “dialogue” between experts from different fields. The book explores the legal basis of sanctions and how this impacts their legitimacy and the perception of their legitimacy.

It considers the complex implications of the extraterritorial effects that sanctions often produce or are even intended to produce, as well as how effective they are in relation to different underlying aims. It is hardly possible to tackle such key questions through a unique disciplinary lens.

This book thus represents an invitation to scholars, experts and decision-makers to adopt an interdisciplinary approach that can no longer be eluded. .
