Karachi is the largest city of Pakistan and the capital of Sindh province, a port metropolis on the Arabian Sea that serves as the country’s principal commercial and financial center. It is also home to Mazar-e-Quaid, the mausoleum of Muhammad Ali Jinnah, the founder of Pakistan.

Where Is Karachi Located?

Karachi sits on the Arabian Sea coast in southern Pakistan, in Sindh province, of which it is the capital. Its natural harbor made it the country’s principal seaport and, by extension, a central hub for national trade since Pakistan’s independence.

A Brief History of Karachi

From Fishing Settlement to Colonial Port

Karachi grew from a small fishing settlement into a major port under British colonial rule in the nineteenth century, after which it developed rapidly as Sindh’s principal commercial city, a growth pattern tied closely to its harbor’s expansion and improving rail and trade links to the rest of British India.

First Capital of Pakistan

When Pakistan became independent in 1947, Karachi served as the country’s first capital, a role it held until the capital moved to Islamabad in the 1960s. Even after that move, Karachi remained Pakistan’s largest city and its principal commercial and financial center.

Mazar-e-Quaid

The mausoleum of Muhammad Ali Jinnah, known as Mazar-e-Quaid, is Karachi’s most recognized monument and sits on a 131.71-acre site that includes Bagh-e-Quaid-i-Azam, a roughly 61-acre garden, according to the government body that manages it.^[1] Architect Yahya C. Merchant’s design was approved in December 1959 at the request of Mohtarma Fatima Jinnah, the founder’s sister, after designs submitted by other architects were not accepted.^[1] Construction began on 8 February 1960, with President Ayub Khan laying the foundation stone later that year; the building was completed on 2 June 1970, and President Yahya Khan inaugurated it on 15 January 1971.^[1] The structure is a square building with an octagonal main chamber beneath a 70-foot dome, faced in Mullaghori white marble, with Jinnah’s actual grave in the basement and a replica displayed in the main chamber above.^[1]

Culture and Economy

Karachi’s population draws on migration from across Pakistan and, following partition, from India, making it one of the most linguistically diverse cities in South Asia, with Urdu, Sindhi, Pashto, Punjabi, and Balochi all widely spoken. Its economy centers on its port, textile and manufacturing industries, and a financial sector anchored by the Pakistan Stock Exchange, reflecting its continuing role as the country’s commercial capital even without the seat of national government.

What Is Karachi Known For?

Karachi is known as Pakistan’s commercial and financial capital and for Mazar-e-Quaid, whose blend of traditional Muslim and modern architectural styles has made it the city’s defining civic monument.^[1] The mausoleum complex also includes the Aiwan-e-Quaid-e-Azam museum, which displays Jinnah’s personal relics, giving the site a role as both a monument and a public institution of national memory.^[1]

Why Karachi Matters

Karachi matters as Pakistan’s largest city, its busiest port, and the resting place of the country’s founder, a combination that has made it both the country’s principal economic engine and a central site of its national identity, even after losing its status as the political capital.
