Lahore is the capital and largest city of the Pakistani province of Punjab. It is the second-largest city in Pakistan, after Karachi, and 27th largest in the world, with a population of over 14 million. Lahore is one of Pakistan's major industrial, educational and economic hubs. It has been the historic capital and cultural centre of the wider Punjab region, and is a major socially liberal, progressive, and cosmopolitan city in the country.
The site of the city has been inhabited for around two millennia, although Lahore itself rose to prominence in the late 10th century. At times Lahore has served as the capital of several empires, including the Odi Shahis, Ghaznavid Empire and Delhi Sultanate. It was one of the principal cities in the Mughal Empire, being its capital city during the reign of Akbar. During this period, it was one of the largest cities in the world. In the 18th century Lahore fell into a period of decay while being contested among the Durranis and the Sikhs; it regained some of its former grandeur when it became capital of the Kingdom of Lahore in the early 19th century. It was annexed to the British Raj in 1849 and became the capital of Punjab Province. Lahore was central to the independence movements of British India, with the city being the site of both the Declaration of Indian Independence and the resolution for the establishment of Pakistan. It suffered rioting during the partition of British India in 1947. Following the independence of Pakistan, Lahore remained the capital of Punjab province.
Lahore is located in central-eastern Punjab, along the Ravi River, and has a strong cultural and political influence over the country being capital of its most populated province. It is a UNESCO City of Literature and major centre for Pakistan's publishing industry, and is as such a foremost centre of Pakistan's literary scene. The city is also a major centre of education, with some of the country's leading universities based there. Lahore is home to Pakistan's Punjabi film industry, and is a major centre of Qawwali music. The city hosts a significant portion of Pakistan's tourism industry, with major attractions including the Walled City, the Badshahi and Wazir Khan mosques, as well as several Sikh and Sufi shrines. Lahore is also home to the Lahore Fort and Shalimar Gardens, both of which are UNESCO World Heritage Sites.
The origin of Lahore's name is unclear. The city's name has been variously recorded by early Muslim historians as Luhawar, Lūhār, and Rahwar. The Iranian polymath and geographer, Abu Rayhan al-Biruni, referred to the city as Luhāwar in his 11th century work, Qanun, while the poet Amir Khusrow, who lived during the Delhi Sultanate period, recorded the city's name as Lāhanūr. Yaqut al-Hamawi records the city's name as Lawhūr, mentioning that it was famously known as Lahāwar. Persian historian Firishta mentions the city as Alahwar in his work, with al-Ahwar being another variation.
One theory suggests that Lahore's name is a corruption of the word Ravāwar, as R to L shifts are common in languages derived from Sanskrit. Ravāwar is the simplified pronunciation of the name Iravatyāwar, a name possibly derived from the Ravi River, known as the Iravati River in the Vedas. Another theory suggests the city's name may derive from the word Lohar, meaning "blacksmith".
According to a legend, Lahore's name derives from Lavpur or Lavapuri (City of Lava), and is said to have been founded by Prince Lava, the son of Sita and Rama. The same account attributes the founding of nearby Kasur to his twin brother Kusha, though it was actually established in the 16th century.
No definitive record of Lahore's early history exists, and its ambiguous historical background has given rise to various theories about its establishment and history.
Alexander the Great's historians make no mention of any city near Lahore's location during his invasion in 326 BCE, suggesting the city had not been founded by that point or was not noteworthy. Ptolemy mentions in his Geography a city called Labokla situated near the Chenab and Ravi rivers which may have been in reference to ancient Lahore, or an abandoned predecessor of the city. Chinese pilgrim Xuanzang gave a vivid description of a large and prosperous unnamed city that may have been Lahore when he visited the region in 630 CE during his tour of India.
The first document that mentions Lahore by name is the Hudud al-'Alam ("The Regions of the World"), written in 982 CE, in which Lahore is mentioned as a town which had "impressive temples, large markets and huge orchards".
Few other references to Lahore remain from before its capture by the Ghaznavid Sultan Mahmud in the 11th century. During this time, Lahore appears to have served as the capital of Punjab under Raja Anandapala of the Üdi Shahi empire, who moved his capital there from Waihind.
Sultan Mahmud conquered Lahore between 1020 and 1027, making it part of Ghaznavid Empire. He appointed Malik Ayaz as its governor in 1021. During the reign of Sultan Ibrahim Malik Ayaz rebuilt and repopulated the city, which had been devastated after the Ghaznavid invasion. He also erected city walls and a masonry fort in 1037–1040 on the ruins of a previous one. During his tenure a confederation of Hindu princes unsuccessfully laid siege to Lahore in 1043–44.
Lahore was formally made the eastern capital of Ghaznavid Empire during the reign of Khusrau Shah in 1152. After the fall of Ghazni in 1163, It became the sole capital. Under their patronage, poets and scholars from other cities of Ghaznavid Empire congregated in Lahore. The city became a cultural and academic centre, renowned for poetry. The entire city of Lahore during the Ghaznavid era was probably located west of the modern Shah Alami Bazaar and north of the Bhatti Gate.
Following the siege of Lahore in 1186, the Ghurid ruler Muhammad captured the city and imprisoned Khusrau Malik, thus ending Ghaznavid rule over Lahore. Lahore was the first capital of the Mamluk dynasty of what would later come to be known as the Delhi Sultanate following the assassination of Muhammad of Ghor in 1206. Under the reign of Mamluk sultan Qutb-ud-Din Aibak, Lahore attracted poets and scholars from medieval Muslim World. Lahore at this time had more poets writing in Persian than any other city. Following the death of Aibak, Lahore first came under the control of the governor of Multan, Nasir ad-Din Qabacha, and then was briefly captured in 1217 by the sultan in Delhi, Iltutmish.
In an alliance with local Khokhars in 1223, the Khwarazmian sultan Jalal al-Din Mangburni captured Lahore after fleeing from Genghis Khan's invasion of his realm. Mangburni then fled from Lahore to the city of Uch Sharif after Iltutmish's army re-captured Lahore in 1228.
The threat of Mongol invasions and political instability in Lahore caused future sultans to regard Delhi as a safer capital for the sultanate, even though Delhi was considered a forward base while Lahore was widely considered as the centre of Islamic culture in northeastern Punjab.
Lahore came under progressively weaker central rule under Iltutmish's descendants in Delhi, to the point that governors in the city acted with great autonomy. Actual Sultanate rule on Lahore lasted only a few decades until the locals reclaimed their autonomy. Lahore was sacked and ruined by the Mongol army in 1241, with the Mongols holding the city for a few years under the rule of the Mongol chief Toghrul.
In 1266, sultan Balban reconquered Lahore, but in 1287 under the Mongol ruler Temür Khan, the Mongols again overran northern Punjab. Because of Mongol invasions, Lahore region became a city on a frontier, with the region's administrative centre shifted south to Dipalpur. The Mongols again invaded northern Punjab in 1298, though their advance was eventually stopped by Ulugh Khan, brother of Sultan Alauddin Khalji of Delhi. The Mongols again attacked Lahore in 1305.
Lahore briefly flourished again under the reign of Ghiyath al-Din Tughlaq (Ghazi Malik) of the Tughluq dynasty between 1320 and 1325, though the city was again sacked in 1329 by Tarmashirin of the Central Asian Chagatai Khanate, and then again by the Mongol chief Hülechü. Khokhars seized Lahore in 1342, but the city was retaken by Ghazi Malik's son, Muhammad bin Tughluq. The weakened city then fell into obscurity and was captured once more by the Khokhar chief Shaikha in 1394. By the time the Mongol conqueror Timur captured the city in 1398 from Shaikha, he did not loot it because it was no longer wealthy.
