Battle of Nowshera in the context of Nowshera, Khyber Pakhtunkhwa

Dost Mohammad Khan Barakzai, (23 December 1792 – 9 June 1863) nicknamed the Great Emir, was the founder of the Barakzai dynasty and one of the prominent rulers of Afghanistan during the First Anglo-Afghan War. With the decline of the Durrani dynasty, he succeeded his brother Sultan Mohammad Khan, and became the Emir of Afghanistan in 1826. An ethnic Pashtun, he belonged to the Mohammadzai branch of the Barakzai tribe. He was the 11th son of Payandah Khan, chief of the Barakzai Pashtuns, who was killed in 1800 by King Zaman Shah Durrani.

At the beginning of his rule, the Afghans lost their former stronghold of Peshawar Valley in March 1823 to the Sikh Khalsa Army of Ranjit Singh at the Battle of Nowshera. The Afghan forces in the battle were led by Mohammad Azim Khan, half-brother of Dost Mohammad Khan. By the end of his reign, he had reunited the principalities of Kandahar and Herat with Kabul. Dost had ruled for a lengthy 36 years, a span exceeded only by Mohammad Zahir Shah more than a century later.

The Emirate of Afghanistan, known internationally as the Emirate of Kabul until 1855, was an emirate in Central Asia that encompassed present-day Afghanistan, parts of present-day Iran, Pakistan, Turkmenistan and Tajikistan. The emirate emerged from its predecessor Durrani Empire, when the Barakzai dynasty prevailed in Kabul.

The history of the Emirate was dominated by the 'Great Game' between the Russian Empire and the British Empire for supremacy in Central Asia. This period was characterized by European influence in Afghanistan. The Emirate of Afghanistan continued the Durrani Empire's war with the Sikh Empire, losing control of the former Afghan stronghold of the Valley of Peshawar at the Battle of Nowshera on 14 March 1823. This was followed in 1838 by the First Anglo-Afghan War with British forces. The war eventually resulted in victory for Afghans, with the British withdrawal in 1842, and Dost Mohammad being reinstalled to the throne. However, during the Second Anglo-Afghan War (1878–1880), the British and Afghans signed the Treaty of Gandamak, which allowed the British to assume control of the Afghan territories within modern-day Pakistan as well as of Afghanistan's foreign affairs, on the condition that a subsidy be paid to the Afghans and the British military fully withdraw. Emir Amanullah Khan signed the Anglo-Afghan Treaty of 1919 following the Third Anglo-Afghan War, gaining full Afghan autonomy, and the removal of Afghanistan's status of being a de-jure British protectorate. In 1926, Amanullah Khan reformed the country as the Kingdom of Afghanistan, becoming its first King.

Bala Hissar (Pashto/Urdu/Hindko: قلعه بالاحصار), also spelt Bala Hisar, is an historic fortress located in Peshawar, Khyber Pakhtunkhwa, Pakistan. First mentioned by 7th-century explorer Xuanzang, the fort was used as a royal residence for the Durrani Empire since 1747, when the Afghan king, Ahmad Shah Durrani, conquered Peshawar. The Marathas briefly occupied it after capturing Peshawar in 1758 but it was soon retaken by the Afghans. The Sikhs destroyed and reconstructed the fort after capturing Peshawar in March 1823. In 1849, the British East India Company reconstructed the fort's outer walls.

The fort now serves as headquarters for Pakistan's Frontier Corps.
