Solidarity in International Law. Challenges, opportunities and the role of...

The principle of solidarity is particularly important now because it is injuxtaposition to some current self-centered trends in politics: the crisesthat have upset the world in recent years, such as migrations, hegemonicaspirations, pandemics, and wars, have made self-evident the inadequacyof such selfish politics. It therefore seems very useful to understandthe role that solidarity could play in contemporary scenarios. Thisbook thus collects various contributions on the principle of solidarity ininternational law. Firstly, it reconstructs the foundations of solidarity inlaw and investigates the origins of the principle. Subsequently, it tries toascertain if solidarity exists as a principle in international law and, if so,what its scope is. The book then examines the eventual implementationof the principle of solidarity in regional organizations law: the questionis whether solidarity is more effective and if it is actually better fulfilledwhen relationships between states get stronger,
