1963 Togolese coup d'état: The 1963 Togolese coup d'état was a military coup that occurred in the country of Togo on 13 January 1963.  The coup leaders (notably Emmanuel Bodjolle, Étienne Eyadéma and Kléber Dadjo) took over government buildings, arrested most of the cabinet, and assassinated Togo's first President, Sylvanus Olympio outside the American embassy in Lomé.  The coup leaders quickly brought Nicolas Grunitzky and Antoine Meatchi, both of whom were exiled political opponents of Olympio, together to form a new government.  While the government of Ghana and its President Kwame Nkrumah were implicated in the coup and assassination of Olympio, full investigation was never completed and the international outcry eventually died down.  The event was important as the first coup d'état in the French and British colonies of Africa that achieved independence in the 1950s and 1960s, and Olympio is remembered as one of the first heads of state to be assassinated during a military coup in Africa.

The government of Prime Minister Konstantin Muraviev was overthrown and replaced with a government of the Fatherland Front led by Kimon Georgiev.  While the Soviet Union supported the coup, their forces (the Third Ukrainian Front) were not directly involved in it, as they had only occupied northeastern Bulgaria at this point.

2012 Malian coup d'état: The 2012 Malian coup d'état began on 21 March, when mutinying Malian soldiers, displeased with the management of the Tuareg rebellion, attacked several locations in the capital Bamako, including the presidential palace, state television, and military barracks.  The soldiers, who said they had formed the National Committee for the Restoration of Democracy and State, declared the following day that they had overthrown the government of Amadou Toumani Touré, forcing him into hiding.  The coup was followed by "unanimous" international condemnation, harsh sanctions by Mali's neighbors, and the swift loss of northern Mali to Tuareg forces, leading Reuters to describe the coup as "a spectacular own-goal".  On 6 April, the junta agreed with Economic Community of West African States (ECOWAS) negotiators that they would step down from power in return for the end of sanctions, giving power to a transitional government led by parliament speaker Dioncounda Traoré.  In the following days, both Touré and coup leader Amadou Sanogo formally resigned; however, as of 16 May, the junta was still "widely thought to have maintained overall control".  On 3 December 2013, a mass grave was discovered in Diago holding the remains of 21 soldiers that went missing the year before, loyal to the ousted president.

On 17 March 1995, units of Azerbaijani Armed Forces surrounded the insurgents in their camp and assaulted it, killing Javadov.  Reports in Turkey following the 1996 Susurluk scandal elaborated on support for the coup from elements in Turkey.
