In the wake of Brexit and the election of Donald Trump, countless words have been written and uttered about nationalism-many accusing nationalists of racism, hatred, and violence. But nationalism wasn't always considered evil. Indeed, such venerated figures as John Stuart Mill, Churchill, Eisenhower, and Ben-Gurion considered themselves nationalists. Were the men and women of that era misguided in their emphasis on self-determination for all peoples?

In The Virtue of Nationalism, the philosopher Yoram Hazony offers an incisively original case for national sovereignty in an era when it is under attack from many sides. He recounts how in the 17th and 18th centuries, English, Dutch, and American Protestants revived the Old Testament's love of national independence, and how their nationalism freed the world from the vision of universal empire promoted by German-Catholic Holy Roman Emperors. Their vision became the basis of opposition to imperialists of later eras, and eventually brought freedom to peoples from Poland to India, and from Israel to Ethiopia.
