Historical Trajectory
Phase I: Rise
Pakistan came into existence on 14 August 1947 following the British Parliament's passage of the Indian Independence Act 1947, which partitioned British India and simultaneously created the Dominion of India. The new dominion comprised provinces and presidencies allocated to it under the Partition of India. In the year following independence, numerous princely states that had held subsidiary alliances with the British signed Instruments of Accession, joining the dominion one by one.
Phase II: Zenith
During its existence as a dominion, Pakistan consolidated a new national administration across two geographically separate regions: West Pakistan and East Pakistan. The government worked to integrate the former princely states, which enjoyed special status within the dominion for several years before gradual incorporation into the provinces. Karachi served as the capital and principal administrative centre, managing the complex task of building state institutions from the foundations of former British colonial governance.
Phase III: Decline
The dominion period ended on 23 March 1956 when Pakistan's first constitution came into force, transforming the country into an Islamic republic and ending its status as a Commonwealth dominion under the Crown. The constitution formally recognised the administrative division into West Pakistan and East Pakistan. These two wings remained part of one republic until 1971, when East Pakistan broke away following a war of independence to become the independent nation of Bangladesh.
