Gujranwala is known as the City of Wrestlers, a nickname reflecting a deep cultural tradition where physical strength and wrestling have been central to the local identity for generations. This moniker distinguishes the city from other major urban centers in Pakistan based on its unique cultural heritage.
Gujranwala was founded by Gurjars in the eighteenth century, though the exact origins of the city remain unclear. It may have been established as a village in the middle of the 16th century, making it a relatively modern city compared to nearby ancient cities like Sialkot and Lahore.
Ranjit Singh, the founder of the Sikh Empire, was born in 1780 in Gujranwala's Purani Mandi market. He maintained Gujranwala as his capital initially after rising to power in 1792 before moving the capital to Lahore in 1799.
Following the Partition of British India in 1947, Gujranwala was the site of some of the worst rioting in Punjab with large swathes of Hindu and Sikh localities attacked or destroyed. By March 1948, over 300,000 refugees had been resettled in Gujranwala District, drastically altering the city's form and demographics.
Gujranwala was incorporated as a municipality in 1867, and the city's Brandreth, Khiyali, and Lahori Gates built atop the site of Sikh-era gates were completed in 1869. A new clocktower was built in central Gujranwala to mark the city's center in 1906.
Today, Gujranwala is Pakistan's third largest industrial center after Karachi and Faisalabad, and contributes 5% to 9% to Pakistan's national GDP. The city forms part of the Golden Triangle of industrial cities along with Sialkot and Gujrat, featuring export-oriented economies.
