This special double issue identifies the tools and conditions that allow (re)emerging autocrats to undermine democratic traditions and constrain civil rights across the world. In our introduction, we posit that identifying the tools of the established, emerging, and aspiring authoritarians in today’s world is vital, theoretically and practically. It allows us to identify common denominators across specific contexts to advance knowledge about the features and risks that authoritarian regimes pose today. It also permits us to reveal the inter-state and transnational expert networks through which autocrats share strategies, information, and resources to remain in power. Through a global and comparative lens, we thematically organize the articles’ key findings. The articles reveal a set of tools of authoritarianism that (re)emerging autocrats use to control media to manipulate public perceptions and delegitimize opponents and critics, seek to maintain the legitimacy of a democratic rule by aligning with “grassroots” social movements composed of extremists and hate organized groups, redefine the meaning of democracy, and use a range of repressive methods domestically and abroad, all while maintaining a façade of democracy. This special issue also captures variation in the successful deployment of autocratic tools as authors caution against equating conditions across different autocratic regimes. We bookend the special issue with a brief reflection on populism on the left and right and what it means for the main themes of the special issue.
