Karachi

Karachi is the biggest city in Pakistan. It is beside the Arabian Sea. Ships come to its port.

Karachi is the largest city in Pakistan and the capital of Sindh province, on the coast of the Arabian Sea west of the Indus River delta. It grew from a small settlement of 1729 into the country's main port, and it was Pakistan's first capital. The 2023 census counted about 18.9 million people.

Karachi, capital of Sindh and by far Pakistan's largest city, grew from the settlement of Kolachi (1729) into a colonial port after British rule came in the late 1830s and 1840s, then into the capital of the new state of Pakistan from 1947 until the government moved north at the end of the 1950s. The 2023 census counted 18,868,021 people in the city, including its cantonments.

Discover Karachi

Karachi is a very big city in Pakistan. Millions and millions of people live there.

It sits by the sea. Ships, boats and fishers use its port.

Karachi is the largest city in Pakistan and the capital of Sindh, one of the country's provinces. It lies on the coast of the Arabian Sea, to the west of the delta where the Indus River meets the sea.

Pakistan's 2023 census counted 18,868,021 people in Karachi, up from 14,884,402 in 2017. Encyclopaedia Universalis notes that the city had only about 400,000 people in 1947, so it has grown very fast.

Karachi is the capital of Sindh province and, in the words of Encyclopaedia Universalis, by far the largest city in Pakistan. It is the country's main port and a center of industry and finance. The city spreads between the sea and the desert, taking in districts such as Clifton and Nazimabad, according to the Gran Enciclopèdia Catalana.

Its growth has been unusually rapid, fed by waves of immigration and by people moving in from the countryside. Universalis gives about 400,000 people in 1947 and a little over 5.2 million in 1981. The censuses counted 14,884,402 people in 2017 and 18,868,021 in 2023, including the cantonments.

A white marble mausoleum, a market and the harbor

Karachi has a big white building with a round dome. It honors the man who founded Pakistan.

Around it is a large park.

The Mazar-e-Quaid is the mausoleum of Muhammad Ali Jinnah, the founder of Pakistan. Its building, faced with white marble and topped by a 70-foot dome, was designed by the architect Yahya C. Merchant and finished in 1970. It stands in a large park, the Bagh-e-Quaid-i-Azam.

Empress Market, a marketplace, appears on an old map of the city's tram lines, which ran from the market to the wharves and cotton presses of the harbor.

The Quaid-i-Azam Mazar Management Board records that an international tender for the design of Jinnah's mausoleum was opened in 1958 and the work was eventually entrusted to the architect Yahya C. Merchant. Work began on 8 February 1960, the foundation stone was laid on 31 July 1960, the marble work started in 1966, and the mausoleum was completed on 2 June 1970. Its builders used 21,200 cubic feet of marble; of the 131.71 acres set aside for it, about 61 acres became the Bagh-e-Quaid-i-Azam park.

An undated map of the Karachi tramways in the Library of Congress shows lines from Empress Market to the wharves and cotton presses, and to McLeod Station, the terminus of the Scinde, Punjaub and Delhi Railway.

From a small settlement to Pakistan's first capital

Long ago, Karachi was a small place by the sea, called Kolachi.

Ships came to trade, and the town grew and grew. Later it became Pakistan's first capital city.

The Library of Congress dates the small settlement of Kolachi, on the Arabian Sea, to 1729. The British East India Company took control of the town in 1838, and in 1843 the whole province of Sindh came under British rule. Trade through the port grew, especially in cotton.

In 1947 British rule in South Asia ended and Pakistan became a new country. Karachi was its first capital, and many people moved to the city from India. At the end of the 1950s the government moved north, first to Rawalpindi and later to Islamabad, but Karachi kept growing.

According to the Library of Congress, Kolachi was established in 1729; in 1800 the British East India Company received permission from local authorities to set up a trading post, and in 1838 it took control of the town. Encyclopaedia Universalis explains why Karachi was slow to rival Bombay: its site was awkward, sheltered only by the Manora spit and the small island of Keamari, and it had little hinterland until Sindh came under British rule in 1843 and cotton growing in the Indus valley expanded during the American Civil War.

Conditions changed sharply after 1948, Universalis says. As capital and then as the main port of West Pakistan and later of Pakistan, Karachi drew industry and many refugees from India. Universalis dates the capital period from 1948 to 1959, the Library of Congress to 1960, when the seat of government moved north to Rawalpindi and then Islamabad. Growth continued after the move.

Through the years

A busy port, early trams and an international airport

Karachi has a big port where ships load and unload.

Long ago, horses pulled trams through the streets. Now planes fly from an international airport.

Karachi's harbor is sheltered by a long, narrow strip of land called Manora and a small island called Keamari. The port was built along a causeway joining Keamari to the mainland. Together with nearby Port Qasim, Encyclopaedia Universalis says, it handles almost all of Pakistan's sea trade.

In the early 1900s, a tram company replaced horse-drawn trams with gas-powered ones. The city also has an international airport, named after Jinnah.

Universalis describes a difficult natural site at the edge of the Indus delta, where the Manora peninsula and the small island of Keamari give shelter; the port was built along a causeway linking Keamari to the mainland. With the neighboring Port Qasim, it says, the port of Karachi carries almost all of Pakistan's maritime trade, as well as that of landlocked Afghanistan.

On land, the Library of Congress recounts that the East India Tramways Company, formed in 1902, steadily replaced horse-drawn trams with gas-powered engines; by 1912 the new trams carried about 46 passengers at 18 mph. The city is also served by Jinnah International Airport.

Hot and very dry, with summer rain

Karachi is warm in winter and hot in summer.

It hardly ever rains. Most rain comes in July and August.

Karachi has warm days all year and is very dry. World Meteorological Organization averages for 1981 to 2010 give January days of about 26 °C and nights of about 12 °C. From May to October, days average 32 to 36 °C.

A whole year brings only about 176 millimeters of rain, and July and August together bring about 121 of them. May gets almost none: just 0.2 millimeters on average.

WMO normals for Karachi (1981–2010) give average highs and lows of 26.3 °C and 11.5 °C in January, the coolest month, rising to 35.5 °C and 26.6 °C in May and 35.4 °C and 28.3 °C in June. October's days are as hot as May's (35.5 °C), though its nights are cooler (21.9 °C).

The monthly rainfall averages add up to only about 176 mm. July (60.1 mm) and August (61.0 mm) bring about two-thirds of it, while May averages 0.2 mm and November 0.5 mm; no other month averages more than about 11 mm.

Fishing, trade and a city of many people

Fishing is still important in Karachi. Many people also work in shops, offices and factories.

Families came to Karachi from many places to live and work.

Fishing has long mattered in Karachi, and Encyclopaedia Universalis says it is still important. Factories, trade, banks and the stock exchange have also brought the city prosperity, and more recently television, film and computer companies have grown.

People have moved to Karachi from all over Pakistan and beyond, which is one reason it has grown so large. The Gran Enciclopèdia Catalana also calls it a cultural center of the country.

Encyclopaedia Universalis traces Karachi's prosperity first to fishing, still important, then to industry (today textiles, pharmaceuticals, steel and cars) and trade, with services now playing a large role through banks, insurance companies and the stock exchange; audiovisual media and information technology have become significant too. Quoting the French geographer Robert Ferras, it calls Karachi a relay through which foreign firms reach Pakistan.

The Gran Enciclopèdia Catalana describes a city that spread between the sea and the desert, absorbing districts such as Clifton, Ghizri, Drigh Road, Lalukhet and Nazimabad, and calls Karachi a cultural center of Pakistan. Both encyclopedias link its growth to migration, from rural areas and, after 1947, from India.
