This research seeks to analyze historical development of federal demand in Pakistan’s constitutional history. Pakistan was established on 14th August 1947 after hard struggle of freedom movement. Pakistan faced territorial distance between its two wings and both wings had different federal perspective, East Pakistan demanded for the provincial autonomy while West Pakistan favored strong center. From the creation of Pakistan towards separation of East Pakistan, there had been tussle between the two parts. The three interim reports of BPC had been rejected by all political parties even some PML members also criticized its unfederal features. The East Pakistan denied all three reports for not accepting provincial autonomy and language demand. The constitution of 1956 and 1962 did not satisfied the federal political demand of East Pakistan during this phase Pakistan also faced two Martial Laws and unfortunately East Pakistan separated from West Pakistan. After missing half part now the west Pakistan seriously decided to draw a federal constitution which had provincial autonomy, equal share of provinces on population base, free judiciary etc. This was the constitution of 1973, this constitution also had been suspended twice Military Dictators twice through amendments and turned the constitution from democratic to presidential. In 2006 political leadership sought to revise the constitution in its real federal democratic shape. All leading political parties signed the historic Charter of Democracy to revise federal constitution. The Eighteenth Constitutional Amendment erased all undemocratic and unfederal features, reorganized the NFC, CCI and abolished the Concurrent legislative list. Subjects were divided between the center and provinces on equal basis to ensure province’s autonomy.
