rough labor, youth, farmers, cooperatives, and other organizations integrated with the CPP. The government, according to Nkrumah, acted only as "the agent of the CPP" in seeking to accomplish these goals.
The CPP's control was challenged and criticized, and Prime Minister Nkrumah used the Preventive Detention Act (1958), which provided for detention without trial for up to 5 years (later extended to 10 years). On July 1, 1960, a new constitution was adopted, changing Ghana from a parliamentary system with a prime minister to a republican form of government headed by a powerful president. In August 1960, Nkrumah was given authority to scrutinize newspapers and other publications before publication. This political evolution continued into early 1964, when a constitutional referendum changed the country to a one-party state. On February 24, 1966, the Ghanaian Army and police overthrew Nkrumah's regime. Nkrumah and all his ministers were dismissed, the CPP and National Assembly were dissolved, and the constitution was suspended. The new regime cited Nkrumah's flagrant abuse of individual rights and liberties, his regime's corrupt, oppressive, and dictatorial practices, and the rapidly deteriorating economy as the principal reasons for its action.
The leaders of the February 24 coup established the new government around the National Liberation Council (NLC) and pledged an early return to a duly constituted civilian government. Members of the judiciary and civil service remained at their posts and committees of civil servants were established to handle the administration of the country. Ghana's Government returned to civilian authority under the Second Republic in October 1969 after a parliamentary election in which the Progress Party, led by Kofi A. Busia, won 105 of the 140 seats. Until mid-1970, the powers of the chief of state were held by a presidential commission led by Brigadier A.A. Afrifa. In a special election on August 31, 1970, former Chief Justice Edward Akufo-Addo was chosen president, and Dr. Busia became prime minister.
Faced with mounting economic problems, Prime Minister Busia's government undertook a drastic devaluation of the currency in December 1971. The government's inability to control the subsequent inflationary pressures stimulated further discontent, and military officers seized power in a bloodless coup on January 13, 1972.
The coup leaders, led by Col. I.K. Acheampong, formed the National Redemption Council (NRC) to which they admitted other officers, the head of the police, and one civilian. The NRC promised improvements in the quality of life for all Ghanaians and based its programs on nationalism, economic development, and self-reliance. In 1975, a government reorganization resulted in the NRC's replacement by the Supreme Military Council (SMC), also headed by now-General Acheampong.
Unable to deliver on its promises, the NRC/SMC became increasingly marked by mismanagement and rampant corruption. In 1977, General Acheampong brought forward the concept of union government (UNIGOV), which would make Ghana a non-party state. Perceiving this as a ploy by Acheampong to retain power, professional groups and students launched strikes and demonstrations against the government in 1977 and 1978. The steady erosion in Acheampong's power led to his arrest in July 1978 by his chief of staff, Lt. Gen. Frederick Akuffo, who replaced him as head of state and leader of what became known as the SMC-2.
Akuffo abandoned UNIGOV and established a plan to return to constitutional and democratic government. A Constitutional Assembly was established, and political party activity was revived. Akuffo was unable to solve Ghana's economic problems, however, or to reduce the rampant corruption in which senior military officers played a major role. On June 4, 1979, his government was deposed in a violent coup by a group of junior and noncommissioned officers--Armed Forces Revolutionary Council (AFRC)--with Flt. Lt. Jerry John Rawlings as its chairman.
The AFRC executed eight senior military officers, including former chiefs o
