In short: In 1739, the Mughal Emperor Muhammad Shah sought safety within the fortified walls of Karnal. Instead, he found a tactical trap. By cutting off his supplies, the Persian invader Nader Shah forced a surrender that fundamentally shifted the balance of power in India.

Karnal’s strategic importance is rooted in its geography. Situated midway between New Delhi and Chandigarh on National Highway 44, it has served as a vital corridor for centuries. This positioning made it a primary theater for major historical shifts, from the 6th-century rule of the Vardhanas to the 10th-century rise of the Tomaras, who established the nearby capital of Delhi.

The city's most dramatic turning point occurred during the Persian invasion of 1739. Nader Shah moved toward Karnal after capturing Sirhind, facing an army of 5,000 infantry and 2,000 cavalry led by Rao Bal Kishan. Though the Mughals held a strongly fortified camp, they were starved into submission as their supplies were severed. This decisive defeat drastically weakened the Mughal Empire and paved the way for the eventual establishment of the British Raj.

Beyond warfare, Karnal has evolved into a hub of modern Indian infrastructure and science. It was ranked 24th in the 2019 Swachh Survekshan as one of India's cleanest cities and was selected for the Smart Cities Mission. Today, it hosts critical research institutions, including the National Dairy Research Institute, which was granted Deemed University status in March 1989, and the National Bureau of Animal Genetics and Resources, established in 1984 to conserve animal genetic resources.

The city also holds deep cultural and political significance. Local tradition links its name to Karna, a figure from the Mahabharata. During the Indian independence movement, it hosted a district political conference chaired by Lala Lajpat Rai. Today, it remains a key administrative and educational center in Haryana, supported by major universities and medical colleges.
