• “Self-coups,” where a leader who came to power legally uses illegal means to remain in power, including the refusal by an incumbent government to relinquish power after free, fair, and regular elections.
• The replacement of a democratically elected government by mercenaries or other external actors will count towards resolution IF they are working in support of a state perpetrator. 

• A civil war, rebellion, or popular uprising.
• Changes to a country’s constitution or laws that infringe on democracy. 

Note regarding the 2021 coup in Chad: In January 2021, president Idriss Déby Itno died in battle against rebel forces, and in response, the military dissolved the government and installed his son, General Mahamat Idriss Déby Itno, as a transitional president in violation of Chad’s constitution (BBC). The U.S. government declined to call this a coup, which would trigger a halt of security assistance funding to a country considered an important ally in the war on terror (Foreign Policy). However, this situation is still considered a coup for the purposes of this question.
