Islamabad
Islamabad (; ) is the capital city of Pakistan, and is federally administered as part of the Islamabad Capital Territory. Built as a planned city in the 1960s to replace Karachi as Pakistan's capital, Islamabad is noted for its high standards of living, safety, and abundant greenery.
History of Karachi
Karachi was chosen as the capital city of Pakistan. After the independence of Pakistan, the city population increased dramatically when hundreds of thousands of Muslim Muhajirs from India fleeing from anti-Muslim pogroms and from other parts of South Asia came to settle in Karachi. As a consequence, the demographics of the city also changed drastically. The Government of Pakistan through Public Works Department bought land to settle the Muslim refugees. However, it still maintained a great cultural diversity as its new inhabitants arrived from the different parts of the South Asia. In 1959, the capital of Pakistan was shifted from Karachi to Islamabad and Karachi became the capital of Sindh.
