The Murtala Mohammed administration set about to revitalise government, the economy and the moral fabric of the society. In the political sphere, government was re-structured to induce greater efficiency and central control by enhancing the roles of the Chief of Staff, Supreme Headquarters, and the Cabinet Office, and limiting the influence of the State Governors.
These became members of a National Council of State and not of the Supreme Military Council (SMC), the highest policy-making body. Panels were appointed to consider the creation of more states and the establishment of a new Federal Capital. In the end, seven more States were created in February 1976, bringing the total number of States to nineteen, and Abuja was selected as the new Federal Capital to which movement would begin in 1986., A programme to return the nation to civilian rule was promulgated and vigorously implemented. A 49 member Constitution Drafting Committee (CDC). appointed in October 1975, produced a draft which was later debated and amended by a partially-elected Constituent Assembly.
In the social sphere, massive purges were effected in the Civil Service, the Judiciary and the Universities, purportedly to remove corrupt, unproductive and/or ageing officials. While the purges might have improved productivity instantly, some were malicious and unjustified. Indeed, on the long run, the purges apparently considerably lowered workers' morale and produced insecurity in the Civil Service previously reputed to provide durable tenure to employees
The hallmark of the Mohammed administration was typified by its dynamic foreign policy, prompt recognition of the MPLA regime in Angola. Although too brief for meaningful assessment, the administration was undoubtedly popular and purposeful. It made considerable achievements before Mohammed was assassinated in an abortive military coup on February 13, 1976.
In pursuit of the return to civilian rule, Local Government Reform, described as "one of the most important legacies" of the First Military Era was instituted in August 1976. It made Local Governments the "third tier" of government (after the Federal and State Governments) and brought government nearer to the people. Local Government elections held the following December partly prepared the Nigerian people for political participation after ten years of military dictatorship.
Further measures to promote the return of civilian rule included the appointment of an Electoral Commission in October 1976 to conduct the state and federal elections, the Constituent Assembly which met from October 1977 to August 1979, and the promulgation of a new constitution, based on the American presidential system, into law in September 1978. The Constitution came into effect on October 1, 1979. Several sensitive issues debated by the Constituent Assembly included demand for the entrenchment of a Federal Sharia Court of Appeal in the Constitution and a Revenue Allocation Formula.
Following nation-wide elections in 1979, on multi-party basis, the new state and national legislatures met in October 1979, and returned Nigeria
to civilian rule under President Shehu Shagari. The hand-over to civilian rule was one of the political successes of the Mohammed - Obasanjo Administration.
The Administration's economic basis rested on the Third National Development Plan (1975 - 1980) earlier launched by General Gowon in March 1975, and subsequently modified by the MurtalaObasanjo Administration. The Plan sought to achieve annual real growth rate of 9.6 per cent, and provided for expansion of agriculture, heavy and petrochemical industries, infrastructure, housing and education.
Agricultural policies and programmes to boost declining food production included the Accelerated Food Production Programme begun in 1974; various World Bank-assisted Agricultural Development Projects (ADP) begun in the mid 1970s; River Basin Development Authority Schemes and the Operation Feed the Nation (OFN) begun by General Obasanjo in 1976. Others were an Agricultural Credit Guarantee Scheme particularly to smallscale farmers, the promulgation of a Land Use Decree in 1978 which nationalised all land, and the establishment of new Commodity Boards. Poor execution of these programmes, a relatively high population growth rate (3 per cent per annum compared with 2 per cent for food), and the premium placed on petroleum exports seriously detracted from the agricultural effort and output. Not only did traditional agricultural exports like palm produce, cotton, groundnut and cocoa decline, but also Nigeria's food imports steadily rose; including imports of palm produce, which Nigeria had been a major world producer and exporter until the late 1960s.
Major industrial and infrastructure developments included steel development, notably at Aladja, Oshogbo and Ajaokuta; new oil refineries built at Warri and Kaduna in 1978 and 1980, respectively, and new port and airport complexes, notably the Murtala Mohammed International Airport in Ikeja, which was opened in April, 1979. Although increasingly contributing to the GDP, industrialisation generally focused on import-substitution and assembly, using mostly foreign technical and managerial expertise despite Government's Indigenisation Policy.
Impressive developments occurred in education and culture. Between 1976 and 1978, the Federal Government introduced Universal Free Primary Education (UPE), assumed responsibility for all the nation's universities, and established a Joint Admissions and Matriculation Board (JAMB) which conducted its first university admissions in 1978 for the 1978/79 Session. The Federal Government also promulgated a new National Policy on Education known as the "6-3-3-4" designed to promote scientific, technical and vocational education and self-employment. To reduce regional imbalances in education, the Federal
