On November 17, 1993 General Sani Abacha, Nigeria's defense minister, forced the interim head of state Ernest Shonekan to resign in a bloodless palace coup and seized power, beginning nearly five years of harsh military dictatorship. Shonekan's Interim National Government, installed in August 1993 after Babangida stepped aside, was weak, lacked legitimacy, and had no control over the military, which Abacha commanded. As pressure mounted, including from supporters of the annulled election's presumed winner Moshood Abiola, Abacha compelled Shonekan to resign on November 17, 1993 and declared himself head of state.
He dissolved the interim government, the legislature, and elected state and local bodies, restoring full military rule. Shonekan was not physically harmed. Abacha ruled until his death in 1998.

The 1993 Nigerian coup was a bloodless military coup on 17 November 1993 when the Armed Forces headed by Defence Minister General Sani Abacha forced Interim President Chief Ernest Shonekan to resign, and in a nationwide broadcast Abacha cited the stagnant nature of Shonekan's government and his inability to manage the democratic process.
As Defence Minister and the senior most military officer Abacha mobilized support within the armed forces and compelled Shonekan to resign, the change was executed without widespread violence and is widely described as a bloodless military coup, and immediately upon assuming control Abacha dissolved the Interim National Government, the federal legislature, state governments, and local councils.

Shonekan's transitional administration lasted only three months before it was overthrown in a palace coup led by General Sani Abacha on 17 November 1993, and in September 1994 Abacha issued a decree that placed his government above the jurisdiction of the courts, effectively giving him absolute power.

Abacha stayed in power until his death on 8 June 1998 at the presidential complex in Abuja, and his regime faced significant international criticism for human rights abuses including the arrest and prosecution of pro-democracy activists and opponents.
Fate coding: the deposed interim head of state Ernest Shonekan was forced to resign and was not physically harmed, matching the dataset. Coding note: the dataset labels this a military coup, accurately, a bloodless palace coup by the defense minister General Sani Abacha, who commanded the armed forces the weak interim government could not control. Arc link: this is the second of two linked Nigeria 1993 records, following Babangida's August 26 handover to the Shonekan interim government; Abacha's seizure ended that three-month interim experiment and restored full military rule. Context recorded and handled neutrally: the takeover came amid the continuing crisis over the annulled June 12, 1993 election, with pressure from supporters of its presumed winner Moshood Abiola; Abacha justified it by citing the interim government's ineffectiveness. Historical weight recorded: Abacha ruled Nigeria as a harsh dictator until his death in 1998, a regime later widely criticized for human-rights abuses and large-scale corruption, recorded as documented later context per its sources. Neutrality maintained on a contested subject.
