Ghana achieved Independence on 6th March, 1957. The political struggles that preceded this historic event date back over a hundred years. In 1957, when Ghana achieved full political Independence the constitution was fashioned after the Westminster model. In June, 1960, ten women were elected by the National Assembly to fill specially created seats. This was done to expose women to parliamentary life. This system of election was not intended to be permanent. The Act made no provision for filling a vacancy caused by death, resignation or expulsion of a woman Member. On 1st July, 1960 Ghana became a sovereign unitary Republic. In February, 1964 Ghana adopted a one-party system of Government. The First National Assembly of the Republic was , dissolved in 1965 and a general election in which all the 198 Members, all of them Members of the national party, the convention People''s Party (C.P.P.) were elected unopposed.The 1964 Constitutional Amendments among other things increased the powers and prerogatives of the President. In February, 1966 the First Republican Government was overthrown by a military coup which installed a military government that remained in power up to September, 1969, when, on its own volition, it handed over power to another constitutionally elected government, and thereby restored parliamentary rule once again. After only 22 months in office the second parliamentary democracy also succumbed to another military rule between January 1972 and October 1979, when under much political pressure, that military government was compelled to usher in the Third Republican parliamentary system. In December 1981 parliamentary democracy was once more thrown into cold storage as a result of yet another military coup. However, the country returned to constitutional rule again on 7th January, 1993.
