The history of the port is intertwined with that of the city of Karachi. Several ancient ports have been attributed in the area including "Krokola", "Morontobara" (Woman's Harbour) (mentioned by
Nearchus),
Barbarikon (the
Periplus of the Erythraean Sea, and
Debal (a city captured by the Arab general
Muhammad bin Qasim in 712 CE). There is a reference to the early existence of the port of Karachi in the "
Umdah", by the Arab navigator
Sulaiman al Mahri (AD 1511), who mentions "
Ras al Karazi" and "
Ras Karashi" while describing a route along the coast from
Pasni to Ras Karashi. Karachi is also mentioned in the sixteenth century
Turkish treatise ''
Mir'ât ül Memâlik'' by the
Ottoman captain
Seydi Ali Reis, who warns sailors about whirlpools and advises them to seek safety in "
Kaurashi" harbour if they found themselves drifting dangerously. In 1728 heavy rains silted up the harbour at
Kharak, forcing merchants to relocate to the area of modern Karachi. In 1729, they built a new fortified town called
Kolachi (also known as
Kalachi-jo-Kun and
Kolachi-jo-Goth) on high ground north of Karachi bay, surrounded by a high mud and timber-reinforced wall with gun-mounted turrets and two gates. The gate facing the sea was called "
Kharadar" (
salt gate), and the gate facing the Lyari River was called "
Mithadar" (
sweet gate). From 1729 to 1783 the strategic location of Kolachi saw the town change hands several times between the
Khans of
Kalat and the rulers of Sind. In 1783, after two prolonged sieges the town fell to the
Talpur Mirs of Sind, who constructed
Manora Fort mounted with cannons on
Manora island at the harbour entrance. |alt= The British were concerned about Russian expansion towards the
Arabian Sea, so in 1839 they occupied Karachi and later the whole of the Sindh. The port served as a landing point for troops during the
First Afghan War. A number of British companies opened offices and warehouses in Karachi and the population increased rapidly. By 1852, Karachi was an established city with a population of 14,000 and a prosperous overseas trade. The modern port began to take shape in 1854, when the main navigation channel was dredged and a mole or
causeway was constructed to link the main harbour with the rest of the city. This was followed by construction of Manora breakwater, Keamari Groyne, the
Napier Mole Bridge and the
Native Jetty Bridge. The construction of the wharves started in 1882, and by 1914 the East Wharf and the Napier Mole Boat Wharf were complete while 1927 and 1944, the West Wharf, the lighterage berths and the ship-repair berths were constructed between 1927 and 1944. By 1899 Karachi was the largest wheat and cotton exporting port in South Asia. The period between 1856 and 1872 saw a marked increase in trade, especially during the
American Civil War when cotton from Sindh replaced American cotton as a raw material in the British textile industry and the opening of the
Suez Canal in 1869. Karachi was an important military base during the
First World War (1914–18) because it was the first
British Raj port of call for ships coming through the Suez Canal and was the gateway to Afghanistan and the Russian Empire. Karachi was again a military base and port for supplies to the Russian front during the
Second World War (1939–1945). In 1947, the British left the region and India and Pakistan were formed. In 1974, a bunch of terrorists seized a Greek ship and held the Greek crew for a number of hours. They wanted the Greek government to meet their demands. After this, the hostages were released and the terrorists fled the country. In November 2025, Pakistan's first-ever standardised
bunkering operations began at Karachi Port. ==Port Terminal Operators==
