This is the first comprehensive, quantitative database on targeted sanctions imposed by the UN since the end of the Cold War. It includes the entire universe of UN targeted sanctions imposed between 1991 and 2014, or 23 different country regimes, broken into 63 case episodes for comparative analysis. Drawing on the work of a consortium of over 50 scholars and policy practitioners worldwide, the database describes all major aspects of UN targeted sanctions regimes, including the types of sanctions, purposes and targets, political, economic and social-psychological impacts, relationship with other institutions, sanctions regimes, and policy instruments, mechanisms of coping and evasion, and unintended consequences. The effectiveness of UN targeted sanctions in each episode is also evaluated on the basis of the multiple – and often simultaneous – purposes of targeted sanctions, to: (1) coerce a change in target’s behaviour, (2) constrain access to resources needed to engage in proscribed activity, and/or (3) signal a violation of an international norm, stigmatizing targets.
