Coups in the World, 1950-Present

The above map reports total coup attempts and is updated through October 2015.
This page provides access to the ongoing data project I have with Clayton Thyne, as well as a more general overview of basic aspects of the data.  We define coups as "illegal and overt attempts by the military or other elites within the state apparatus to unseat the sitting executive," and successes as episodes in which the perpetrators control power for at least 7 days.  All data on this page are updated continuously.  We attempt to update the data in near-real time, so I will add a disclaimer that any coded events that are ongoing should be treated as tentative.  I strongly encourage anyone with comments, questions, or concerns with the data to contact me.
