This research paper evaluates the rise and fall of the Unionist Party since its formation to eventual breakdown in the Punjab province. The power base of the Unionist Party largely vested in landlords, the pirs and sajjadah nashins who played a pivotal role in the ups and downs of the party. In addition to this, the tug of war between the Unionist Party and the Muslim League has closely been taken into consideration to strengthen the argument that how the soaring fame of the latter proved to be a death-knell for the existence of the former. This study further re-assesses the mercurial loyalties of the major stakeholders along with political developments laced with their repercussions in the Punjab politics. Moreover, it also reflects the traditional ways of the rural politics to be an interesting phenomenon in the Colonial Punjab. Theoretically, this paper presents the complete course of the Unionist Party in the light of Ibn-e-Khaldun‟s theory of „Rise and Fall‟ that has been meticulously engaged to substantiate this research work. In fact, it provides a comprehensive account of the party‟s emergence, growth and ultimate collapse in the British Punjab.
