A key test to understand the resurgence of nationalisms. The end of the cold war brought with it the resurgence of nationalism, a romantic ideology that seemed overcome. To be able to live this phenomenon closely and try to understand it, Ignatieff undertook a trip to six key places of the new nationalism: the former Yugoslavia, Germany, Ukraine, Quebec, Kurdistan and Northern Ireland. The result is a brilliant essay, which is still topical, in which Ignatieff warns of the dangers of nationalism when it becomes an exclusive force. Blood and belonging is a necessary work to understand nationalism and its different manifestations, and also a wake-up call that can not be ignored. Today, nationalism continues to be one of the most politically relevant issues, and this is an essential book to understand its appeal and its validity.
