Since the publication of the third edition of Critical Race Theory: An Introduction in 2017, the United States has experienced a dramatic increase in racially motivated mass shooting and a pandemic that revealed how deeply entrenched medical racism is and how public disasters disproportionately affect minority communities. We have also seen a sharp backlash against Critical Race Theory, and a president who deemed racism a thing of the past while he fanned the flames of racial intolerance and promoted nativist sentiments among his followers. Now more than ever, the racial disparities in all aspects of public life are glaringly obvious. Taking note of all these developments, this fourth edition covers a range of new topics and events and addresses the rise of a fierce wave of criticism from right-wing websites, think tanks, and foundations, some of which insist that America is now colorblind and has little use for racial analysis and study. Award-winning authors Richard Delgado and Jean Stefancic also address the rise in legislative efforts to curtail K-12 teaching of racial history. Critical Race Theory, Fourth Edition is essential for understanding developments in this burgeoning field, which has spread to other disciplines and countries. The new edition also covers the ways in which other societies and disciplines adapt its teachings and, for readers wanting to advance a progressive race agenda, includes new readings and questions for discussion aimed at outlining practical steps to achieve this objective.
