The Sikh Empire was a regional power based in the Punjab region of the Indian subcontinent. It existed from 1799, when Maharaja Ranjit Singh captured Lahore, to 1849, when it was defeated and conquered by the British East India Company in the Second Anglo-Sikh War. It was forged on the foundations of the Khalsa from a collection of autonomous misls. At its peak in the 19th century, the empire extended from Gilgit and Tibet in the north to the deserts of Sindh in the south and from the Khyber Pass in the west to the Sutlej in the east as far as Oudh. It was divided into four provinces: Lahore, which became the Sikh capital; Multan; Peshawar; and Kashmir from 1799 to 1849. Religiously diverse, with an estimated population of 4.5 million in 1831, it was the last major region of the Indian subcontinent to be annexed by the British Empire.

The Khyber Pass is a mountain pass in the Khyber Pakhtunkhwa province of Pakistan, on the border with the Nangarhar Province of Afghanistan. It connects the town of Landi Kotal to the Valley of Peshawar at Jamrud by traversing part of the White Mountains. Since it was part of the ancient Silk Road, it has been a vital trade route between Central Asia and the Indian subcontinent and a strategic military choke point for various states that controlled it. The Khyber Pass is considered one of the most famous mountain passes in the world.
