Karachi

Karachi ( Sindhi: ڪراچي, Urdu: کراچی) is the provincial capital of Sindh province and the largest city in Pakistan. Karachi is the world's second largest city proper behind Mumbai in terms of population, which exceeds 12 million. In terms of population, it is one of the largest cities in the world, and is Pakistan's premier centre of banking, industry, and trade. Karachi is also the home of Pakistan's largest corporations that are involved in entertainment, publishing, software development, medical research. It also serves as a major hub of higher education in South Asia, and the wider Islamic World.
Karachi was the original capital of Pakistan until the construction of Islamabad, and is the location of Karachi Port, one of the regions largest and busiest ports. The city's population has since increased dramatically after the partition of British India forced hundreds of thousands of Urdu and Gujrati speaking "Mohajirs"(refugees) to settle in the city. Since independence from Britain in 1947, the city's vibrant economy has attracted migrants from all over Pakistan, and beyond. Despite a history of political turmoil, the city continues to attract those seeking prosperity.
Karachi city is expansive, and is over 3,530 square kilometres (1,363 sq mi) in area. It is locally known as the "City of Lights" (روشنين جو شهر) for its liveliness, and the "City of the Quaid" (شهرِ قائد), having been the birth and burial place of Quaid-e-Azam Muhammad Ali Jinnah, the founder of Pakistan, who also made the city his home after Pakistan's independence.
