Pakistan suffered from the crisis of democracy many times. Its history stands witness to the frequent dissolution of assemblies before the completion of their respective constitutional terms, the intermittent breakdown of the constitutions, take-over of military, disintegration and perpetual bad governance. The study attempts to unfold the rivalries behind the crisis of democracy that did not allow democracy to take roots in the period 1988 to 1999. It seeks to analyze that how the role of leadership both in government and in opposition through their mutual rivalries for political and economic gains generated a wave of political crisis that in turn gave birth to the crisis of democracy in the period and to what extent systemic factors played their role in deepening the crisis of democracy during 1990s. The state of affairs, in the period 1990s, was the result of the leadership and their personal gains and losses as well as of systemic factors out of their rivalries that made democracy suffered. The study attempted to analyze the role of leadership in the persons of Benazir and of Nawaz Sharif in their respective terms in office as the head of the government and the head of the opposition that how they played their role in the crisis of democracy in the period under study as well as the role of the President in the persons of Ghulam Ishaq Khan, of Farooq Ahmed Khan, and of General Pervaiz Musharruf. There were existed certain kinds of rivalries among them that was repeated and escalated and created crisis that gave way to an integrated group of elites to play their role in deepening the crises. Consequently, democracy was suffered in the period 1988-99. Systemic factors were an integrated group of elites that influenced the political system of Pakistan and played their role in deepening the crisis of democracy in the period. The group consisted of elites both political and non-political and played a decisive role in the crisis. Besides, it was a perpetual and manipulating factor in the crisis and worked as a group. The group collaborated with the man at the helm based on similar interests against the common rival. It was heterogeneous in the making consisting of political-religious-civil military-judicial elites. It remained united throughout the decade of democracy and played their role in deepening the crises. Consequently, democracy suffered from crisis in the period 1988-99. The popular and semi-academic discussion regarding civil- military tension and crisis of democracy generally lead to a conclusion that the institution of military is the main cause and politicians are the main victims in the derailment of democracy.
