This book examines one of the most important political developments of the twenty-first century, the emergence of the populist radical right. By exploiting popular discontent among those who feel left behind in a rapidly changing world, populist radical right politicians have attained power. Once in power, they have often implemented policies that worsen the conditions for those who supported them yet manage to retain their support by blaming others. Aided by social media, they have promulgated the most bizarre conspiracy theories, creating dangerous fractures in society and undermining long-established institutional safeguards of public health. In this way, they can perpetuate the conditions that enabled their rise to power, but at a terrible human cost.
