Kuala Lumpur (KL), officially the Federal Territory of Kuala Lumpur, is the capital city and a federal territory of Malaysia. It is the most populous city in the country, covering an area of 243 km2 (94 sq mi) with a population of 2,111,536 as of 2026. Greater Kuala Lumpur, which itself includes the Klang Valley, is an urban agglomeration of 8.81 million people as of 2024. It is among the fastest growing metropolitan regions in Southeast Asia, in terms of both population and economic development.
The city serves as the cultural, financial, tourism, political and economic centre of Malaysia. It is also home to the Malaysian parliament (consisting of the Dewan Rakyat and the Dewan Negara) and the Istana Negara, the official residence of the monarch (Yang di-Pertuan Agong). Kuala Lumpur was first developed around 1857 as a town serving the tin mines of the region, and important figures such as Yap Ah Loy and Frank Swettenham were instrumental in the early development of the city during the late 19th century. It served as the capital of Selangor from 1880 until 1978. Kuala Lumpur was the founding capital of the Federation of Malaya and its successor, Malaysia. The city remained the seat of the executive and judicial branches of the Malaysian federal government until these were relocated to Putrajaya in early 1999. However, some sections of the political bodies still remain in Kuala Lumpur. The city is one of the three Federal Territories of Malaysia, enclaved within the state of Selangor, on the central west coast of Peninsular Malaysia.
Since the 1990s, the city has played host to many international sporting, political and cultural events, including the 1998 Commonwealth Games, 2001 Southeast Asian Games, 2017 Southeast Asian Games, Formula One, Moto GP and 1997 FIFA World Youth Championships. Kuala Lumpur has undergone rapid development in recent decades and is home to the tallest twin buildings in the world, the Petronas Towers, which have since become an iconic symbol of Malaysian development. Kuala Lumpur is well connected with neighbouring urban metro regions such as Petaling Jaya via the rapidly expanding Klang Valley Integrated Transit System. Residents of the city can also travel to other parts of Peninsular Malaysia as well as to Kuala Lumpur International Airport (KLIA) via rail through Kuala Lumpur Sentral station.
Kuala Lumpur was ranked the 6th most-visited city in the world on the Mastercard Destination Cities Index in 2019. The city houses three of the world's ten largest shopping malls. Kuala Lumpur ranks 70th in the world and second in Southeast Asia after Singapore in the Economist Intelligence Unit's Global Liveability Ranking and ninth in Asia-Pacific and second in Southeast Asia after Singapore in KPMG's Leading Technology Innovation Hub 2021. Kuala Lumpur was named World Book Capital 2020 by UNESCO. In 2025, Kuala Lumpur was ranked second for the best outstanding city in Southeast Asia, after Singapore, and 79th in the world by the Oxford Economic Papers' Global Cities Index.
Kuala Lumpur means "muddy confluence" in Malay: kuala is the point where two rivers join, or an estuary, and lumpur means "mud". One suggestion is that it was named after Sungai Lumpur ("muddy river"); in the 1820s, a place named Sungei Lumpoor was said to be the most important tin-producing settlement on the Klang River. However, Kuala Lumpur lies at the confluence of the Gombak and Klang rivers and therefore should be called Kuala Gombak, since the kuala is typically named after the river that joins a larger river or the sea. Some have argued that Sungai Lumpur extended to the confluence, therefore, the point where it joined the Klang River would be Kuala Lumpur. This Sungai Lumpur is speculated to be Treacher Valley Stream that joined the Klang River 1.5 kilometres (1 mile) upstream from the Gombak confluence near Bukit Nanas, or perhaps a river located to the north of the Batu Caves area.
It has also been proposed that Kuala Lumpur was originally named Pengkalan Lumpur ("muddy landing place"), but became corrupted into Kuala Lumpur. Another theory says that it was initially a Cantonese word, lam-pa, meaning "flooded jungle" or "decayed jungle". There is no firm contemporary evidence for these suggestions other than anecdotes, however. The name may also be a corrupted form of an earlier forgotten name.
The official account considers Kuala Lumpur to have been founded by the Malay Chief of Klang, Raja Abdullah, who sent Chinese miners into the region to open tin mines in 1857, although it is unclear who the first settlers were since there were likely settlements at the Gombak-Klang river confluence before that in the 1820s. The indigenous Temuan people may have inhabited the area for some time, Chinese miners were known to be involved in tin mining up the Selangor River in the 1840s about 16 kilometres (10 miles) north of present-day Kuala Lumpur, and Mandailing Sumatrans led by Raja Asal and Sutan Puasa were also involved in tin mining and trade in the Ulu Klang region before 1860, and Sumatrans may have settled in the upper reaches of Klang River in the first quarter of the 19th century, or possibly earlier. Kuala Lumpur was originally a small hamlet of just a few houses and shops at the confluence of the Sungai Gombak and Sungai Klang (Klang River). Kuala Lumpur became established as a town c. 1857, when Raja Abdullah bin Raja Jaafar, aided by his brother Raja Juma'at of Lukut, raised funds from Malaccan Chinese businessmen to hire Chinese miners from Lukut to open new tin mines there. The miners landed at Kuala Lumpur and continued on foot to Ampang, where they opened the first mine. Kuala Lumpur was the furthest point up the Klang River to which supplies could conveniently be brought by boat and therefore became a collection and dispersal point serving the tin mines.
Despite a high death toll from the malarial conditions of the jungle, the Ampang mines succeeded and exported the first tin in 1859. At that time, Sutan Puasa was already trading near Ampang. Two traders from Lukut, Hiu Siew and Yap Ah Sze, arrived in Kuala Lumpur and set up shops to sell provisions to miners in exchange for tin. The town, spurred on by tin-mining, started to develop around Old Market Square (Medan Pasar), with roads radiating out towards Ampang as well as Pudu and Batu (the destinations became the names of these roads: Ampang Road, Pudu Road, and Batu Road), where miners had also begun to settle in, and Petaling and Damansara. The miners formed gangs and the gangs frequently fought in this period, particularly factions of Kuala Lumpur and Kanching, mainly over control of the best tin mines. Leaders of the Chinese community were conferred the title of Kapitan Cina (Chinese headman) by the Malay chief, and Hiu Siew, the early Chinese trader, became the first Kapitan of Kuala Lumpur. The third Chinese Kapitan of Kuala Lumpur, Yap Ah Loy, was appointed in 1868.
After the mines were opened, Raja Abdullah then sent a garrison under the command of a Bugis lieutenant to man a stockade built at Bukit Nanas. Important Malay figures of early Kuala Lumpur also included Haji Mohamed Tahir, who became the Dato Dagang ("chief of traders"). The Minangkabaus of Sumatra became another important group who traded and established tobacco plantations in the area. Notable Minangkabaus included their headman, Dato' Sati, Utsman Abdullah, and Haji Mohamed Taib, who was involved in the early development of Kampung Baru. The Minangkabaus were also significant socio-religious figures, for example Utsman bin Abdullah was the first kadi of Kuala Lumpur, as well as Muhammad Nur bin Ismail.
Beginning of modern Kuala Lumpur
Early Kuala Lumpur was a small town that suffered from many social and political problems – the buildings were mostly made of wood and 'atap' (palm frond thatching). The buildings were prone to catching fire, and due to a lack of proper sanitation, the town was plagued with diseases. It also suffered from a constant threat of flooding due to its location. The town became embroiled in the Selangor Civil War in part over control of revenue from the tin mines. Yap Ah Loy allied himself with Tengku Kudin and the Hai San secret society, they fought against a rival secret society, Ghee Hin, who allied themselves with Raja Mahdi. Raja Asal and Sutan Puasa switched sides to Raja Mahdi, and Kuala Lumpur was captured in 1872 and burnt to the ground. Kudin escaped to Klang where he assembled another fighting force and recaptured Kuala Lumpur in March 1873, defeating Raja Mahdi's forces with the help of Pahang's military under Ahmad Muʽazzam. The war and other setbacks, such as dropping tin prices, led to a slump. A major outbreak of cholera caused many to flee. The slump lasted until late 1879, when rising prices for tin allowed the town to recover. In late 1881, the town was severely flooded, after a fire that had destroyed the entire town in January. With the town being rebuilt a few times and having thrived, this was due in large to Yap Ah Loy. Yap, together with Frank Swettenham who was appointed the Resident in 1882, were the two most important figures of early Kuala Lumpur with Swettenham credited with its rapid growth and development and its transformation into a major urban centre.
