Johnson Thomas Umunnakwe Aguiyi-Ironsi (3 March 1924 – 29 July 1966) was a Nigerian military officer who was the first military head of state of Nigeria.
Thomas Umunnakwe Aguiyi-Ironsi was born into the family of Igbo people Ezeugo Aguiyi on 3 March 1924, in Ibeku, Umuahia, now in Abia State, Nigeria.
Aguiyi-Ironsi subsequently took the last name of his brother-in-law as his first name in admiration of Mr. Johnson for the father-figure role that he played in his life.
Aguiyi-Ironsi had his primary and secondary school education in Umuahia and Kano, respectively.
At the age of 18, he joined the Nigeria Regiment against the wishes of his sister, Anyamma.
1942
In 1942, Aguiyi-Ironsi joined the Nigerian Regiment, as a private with the seventh battalion.
1946
He was promoted in 1946 to company sergeant major.
Also in 1946, Aguiyi-Ironsi was sent on an officer training course in Staff College, Camberley, England.
1949
On 12 June 1949, after completion of his course at Camberley, he received a short-service commission as a second lieutenant in the Royal West African Frontier Force, with a subsequent retroactive promotion to lieutenant effective from the same date.
1953
Aguiyi-Ironsi was granted a regular commission on 16 May 1953 (seniority from 8 October 1947), and was promoted to captain with effect from the same date (seniority from 8 October 1951).
1956
Aguiyi-Ironsi was one of the officers who served as equerry for Queen Elizabeth II of the United Kingdom and Nigeria when she visited Nigeria in 1956 and so he was appointed a Member of the Royal Victorian Order (MVO).
1958
He was promoted to Major on 8 October 1958.
1960
In 1960, Aguiyi-Ironsi was made commandant of the fifth battalion in Kano, Nigeria, with the rank of lieutenant colonel.
Later in 1960, Aguiyi-Ironsi headed the Nigerian contingent force of the United Nations Operation in the Congo.
1961
From 1961 to 1962, Aguiyi-Ironsi served as the military attaché to the Nigeria High Commission in London, United Kingdom.
During that period he was promoted to the rank of brigadier.
During his tenure as military attaché, he attended courses at the Imperial Defence college (renamed Royal College of Defence Studies in 1961), Seaford House, Belgrave Square.
1962
He was appointed a Member of the Order of the British Empire, Military Division (MBE) in the 1962 New Year Honours list.
1964
In 1964, he was appointed as the commandant of the entire United Nations peace keeping force in the Congo.
1965
In 1965, Aguiyi-Ironsi was promoted to the rank of major general.
The same year, Major General C.B. Welby-Everard handed over his position as the general officer Commanding, GOC of the entire Nigerian Army to Major General Johnson Thomas Umunnakwe Aguiyi-Ironsi, which made him the first Nigeria indigenous officer to head the entire Nigerian Army.
1966
He seized power during the ensuing chaos after the 15 January 1966 military coup.
He ruled from 16 January 1966 until his assassination by a group of mutinous Northern Nigerian officers and men who were led by Major Murtala Mohammed and included Captain Theophilus Danjuma, Lieutenant Muhammadu Buhari, Lieutenant Ibrahim Babangida and Lieutenant Sani Abacha in a revolt against his government in what was popularly called the July counter-coup.
In January 1966, a group of army officers, led by Major Chukwuma Nzeogwu, overthrew the central and regional governments of Nigeria, killed the prime minister and tried to take control of the government in a failed coup d'état.
Nzeogwu was countered, captured and imprisoned by Major General Aguiyi-Ironsi.
Aguiyi-Ironsi was named military head of state on 17 January 1966, a position he held until 29 July 1966, when a group of Northern army officers revolted against the government and killed Aguiyi-Ironsi.
On 15 January 1966, soldiers of mostly Igbo extraction, led by Major Chukwuma Kaduna Nzeogwu, an Igbo from Okpanam near Asaba, Noé in Delta State, eradicated the uppermost echelon of politicians from the Northern and the Western Provinces.
That and other factors effectively led to the fall of the Republican Government.
Aguiyi-Ironsi, an Igbo, was purportedly slated for assassination but effectively took control of Lagos, the Federal Capital Territory.
Also an Igbo, President Nnamdi Azikiwe refusing to intervene to ensure the continuity of civilian rule, Aguiyi-Ironsi effectively compelled the remaining members of Balewa's government to resign.
Seeing that the government was in disarray, Aguiya-Ironsi then allowed Senate President Nwafor Orizu, another Igbo who was serving as acting president in Azikiwe's absence, to surrender power to him officially, which ended the First Nigerian Republic.
Aguiyi-Ironsi inherited a Nigeria that was deeply fractured by its ethnic and religious cleavages.
None of the high-profile victims of the 1966 coup was of Igbo extraction, and the main beneficiaries of the coup were Igbo.
Those facts led the north the country to believe that it had been an Igbo conspiracy.
Though Aguiyi-Ironsi tried to dispel that notion by courting the aggrieved ethnic groups through political appointments and patronage, his failure to punish the coup plotters and the promulgation of the now-infamous "Decree No. 34", which abrogated the country's federal structure in exchange for a unitary one, crystallized the conspiracy theory.
During his short regime (194 days in office), Aguiyi-Ironsi promulgated a raft of decrees.
Among them were the Constitution Suspension and Amendment Decree No.1, which suspended most articles of the Constitution though it left intact those sections that dealt with fundamental human rights, freedom of expression and conscience.
The Circulation of Newspaper Decree No.2 removed the restrictions on press freedom that had been put in place by the preceding civilian administration.
According to Ndayo Uko, the decree was to serve "as a kind gesture to the press" to safeguard himself when he went on later to promulgate the Defamatory and Offensive Decree No.44 of 1966, which made it an "offense to display or pass on pictorial representation, sing songs, or play instruments the words of which are likely to provoke any section of the country".
He also, as per the proposals of a single-man committee, passed the controversial Unification Decree No. 34, which aimed to turn Nigeria into a unitary state.
