The 1962 Constitution of Pakistan was a significant legal document that established the framework for the country's governance. It replaced the previous constitution of 1956 and aimed to create a more centralized government. The constitution introduced a presidential system, granting extensive powers to the President, while also outlining the roles of the legislature and judiciary. This constitution emphasized the importance of Islamic principles in governance and aimed to promote national unity. However, it faced criticism for concentrating power in the executive branch. The 1962 Constitution was eventually abrogated in 1969, leading to a period of political instability in Pakistan.
