West Pakistan
West Pakistan formed a block whose people seemed homogeneous (similar to each other). However, the new region included people of different ethnicities and languages. The "One Unit Policy" was regarded as a rational administrative reform which would reduce spending and eliminate provincial prejudices. However with the military coup of 1958, trouble loomed for the province when the office of Chief Minister was abolished and the President took over executive powers for West Pakistan. The province of West Pakistan was dissolved in July 1970 by President Yahya Khan.
