The Khyber Pass, (Pashto: د خیبر درہ, Urdu/Persian: درۂ خیبر) (altitude: 1,070 m or 3,510 ft) is a mountain pass connecting Afghanistan and Pakistan, cutting through the northeastern part of the Spin Ghar mountains. An integral part of the ancient Silk Road, it is one of the oldest known passes in the world. Throughout history it has been an important trade route between Central Asia and South Asia and a strategic military location. The summit of the pass is 5 kilometres (3.1 mi) inside Pakistan at Landi Kotal.

Well known invasions of the area have been predominantly through the Khyber Pass, such as the invasions by Darius I and Alexander the Great and also include Genghis Khan and later Mongols such as Duwa, Qutlugh Khwaja and Kebek. Among the Muslim invasions of South Asia, the famous invaders coming through the Khyber Pass are the Turks such as Mahmud Ghaznavi, Muhammad Ghori and the Turkic-Mongols such as Timur Lane and Babur whose invasion resulted in the establishment of the celebrated Mughul Empire (1526-1857). During the Mughal Period India was again invaded by the Persians under Nadir Shah and later by the Afghans under Ahmad Shah Durrani; all these invasions coming through the Khyber Pass. The British invaded Afghanistan from India via the pass and fought three Afghan Wars in 1839-42, 1878-80, and 1919. George Molesworth, a member of the British force of 1919, summarized: "Every stone in the Khyber has been soaked in blood." Rudyard Kipling called it "a sword cut through the mountains."

Hari Singh Nalwa (1791–1837) was Commander-in-chief of the Khalsa, the army of the Sikh Empire. He is known for his role in the conquests of Kasur, Sialkot, Multan, Kashmir, Attock, Peshawar and Jamrud. In 1813 he accompanied Diwan Mohkam Chand on an expedition to Kashmir which helped Maharaja Ranjit Singh to become the master of the Koh-i-Noor diamond.

Hari Singh Nalwa was responsible for expanding the frontier of Sikh Empire to beyond the Indus River right up to the mouth of the Khyber Pass. In 1831, he opposed moves by Ranjit Singh to appoint Kharak Singh as his successor as Maharaja of the Sikh Empire. At the time of his death, the western boundary of the Sikh Kingdom was Jamrud. His frontier policy of holding the Khyber Pass was later used by the British Raj.

He served as governor of Kashmir, Peshawar and Hazara and established a mint on behalf of the Sikh Empire to facilitate revenue collection.

Hari Singh's ancestors came to Majitha and served the Sukerchakia Misl. His grandfather, Hardas Singh, was killed in action in 1762. His father, Gurdial Singh, served under Charat Singh and Maha Singh as a Risaldar and received the Jagir of Balloki, a village in the modern day Kasur District of Pakistan.

Maharaja Hari Singh (23 September 1895, Jammu–26 April 1961, Bombay) was the last ruling Maharaja of the princely state of Jammu and Kashmir in India.

He was married four times. With his fourth wife, Maharani Tara Devi (1910–1967), he had one son, Yuvraj (Crown Prince) Karan Singh.

Hari Singh was born on 23 September 1895 at the palace of Amar Mahal, Jammu, the only surviving son of General Raja Sir Amar Singh (14 January 1864-26 March 1909), the younger son of General Maharajadhiraj Sri Sir Ranbir Singh and the brother of Lieutenant-General Maharajadhiraj Sri Sir Pratap Singh, the then Maharaja of Jammu and Kashmir.

In 1903, Hari Singh served as a Page of Honour to Lord Curzon at the grand Delhi Durbar. At the age of 13, Hari Singh was dispatched to Mayo College in Ajmer. A year later in 1909, when his father died, the British took a personal interest in his education and appointed Major H.K. Brar as his guardian. After Mayo College the ruler-in-waiting went to the Imperial Cadet Corps at Dehra Dun for military training, imbibing its British upper-crust atmosphere and polishing his English to a high gloss, and by the age of 20 he had been appointed commander-in-chief of the Jammu and Kashmir state forces.
