An ideal I live for. They are almost fifty years from the first to the last page of this book. They are years of political formation, fight, prison, clashes, multitudinous mítines and quiet reflexion moments. They are years in which its author´s life; Nelson Mandela and the life of his country; South Africa, join together in a common trajectory which will finally end up in the international censure of the apartheid segregationist and racialistic regime and its later fall. It is a summary of different texts against the social inequalities; in favour of the recognition off all those political prisoners´ rights in the world and the respect among communities which gives the word a trascendence beyond the own author´s life or the historical circumstances in which this book was written. Un ideal por el cual vivo ( An ideal I live for) is the direct testimony of the political evolution and vital commitments of one of the most charismatic leaders in the 20th century; as well as the testimony of the fight of a country which put all its expectations on him.
