The struggle that broke out on February 21, 2026 between Afghanistan and Pakistan is a continuation of an previous war, the primary roots of which return to the colonial generation and the demarcation of the typical border in 1893, the well-known “Durand Line”.
Within the nineteenth century, the “Great Game” pitted the Russian Empire in Central Asia, whose regulate prolonged so far as former Turkestan – within the Turkmen, Uzbek and Tajik lands – to the British Crown, whose western border of the British Raj (British India) incorporated the Indus River, in present-day Pakistan.
Between those two spaces, the Emirate of Afghanistan used to be already a sovereign state, in part tribal, multi-ethnic with a majority of Pashtuns and a multi-religious state with a majority of Sunni Muslims.
A buffer zone between the Russian Empire and the British Reich
For the British, Afghanistan represented a buffer zone in opposition to the Russian expansionist possibility. Due to this fact, they attempted to take it by means of drive 3 times: between 1839 and 1842, between 1878 and 1880, then between Might and August 1919.
The First Warfare (1839-1842) used to be gained by means of the Afghans below Dost Mohammad Khan after the Combat of Gandamak in January 1842. The British troops engaged, in addition to their Indian auxiliaries, have been decimated. Simplest Dr. William Brydon, a military surgeon, survived and controlled to flee on horseback to record his tale to the government stationed in Jalalabad, Nangarhar province.
The Remnants of the Military, painted by means of Elizabeth Thompson in 1879, presentations an exhausted William Brydon getting back from the crisis at Gandamac.
The second one struggle (1878-1880) used to be one in every of revenge. The Congress of Berlin in July 1878 used to be marked by means of a diplomatic dating of energy between the Russian Empire and the British Crown for regulate of the Balkans and jap get right of entry to to the Mediterranean. After him, so as to deal with affect in Central Asia, Russian emissaries have been despatched to Kabul to Sher Ali Khan (son of Dost Mohammad Khan), which straight away provoked the response of Lord Lytton, the (British) Viceroy of India, who used to be frightened of Russian-Afghan collusion. In September 1878, Lytton despatched his diplomatic venture led by means of Neville Bowles Chamberlain to Kabul, nevertheless it used to be blocked by means of Afghan forces within the Khyber Go. The Emir, saddened by means of the hot loss of life of his younger son Prince Abdullah Yan, didn’t intend to offend the Russians by means of welcoming the British delegation, which he thought to be colonialist.
Lytton then formulated an ultimatum: Afghanistan will have to conform to host his venture ahead of November 1878, or he would pass at the offensive. And not using a reaction inside of that point, war broke out and this time the British gained. They then took regulate of Peshawar (within the Pashtun zone) and Quetta (in Baluchistan), at the borders of the respective territories of the combatants. This merit used to be formalized by means of the Treaty of Gandamak, signed on Might 26, 1879 by means of Louis Kawanyari, the British consultant, and Muhammad Yaqub Khan (son of Sher Ali Khan, who died in Mazar-e-Sharif whilst fleeing against the Russian border).
Two months later, in July 1879, Cavagnari used to be appointed everlasting consultant in Kabul. However Bala Hissar (“The Castle Above”), the seat of the British embassy, used to be temporarily besieged after which set on hearth by means of Afghan rebels difficult their pay, on September 3, 1879. Kavanjar and his whole delegation have been killed.
Litton’s response didn’t take lengthy. British troops, led by means of Frederick Roberts, then occupied Kabul. Mohammad Yakub Khan abdicated on October 12, 1879 and went into exile in India.
Civil struggle adopted below army career and the British supported the upward thrust to energy of Abdur Rahman Khan (nephew of Sher Ali Khan). He has, actually, agreed to desert his international coverage in change for troop withdrawals and promises to deal with regulate of inner affairs. It used to be on this context that Afghanistan and the British Raj have been separated by means of a border of two,430 kilometers, in line with the bilateral settlement of November 12, 1893 concluded between the Emir and Sir Henry Mortimer Durand: the well-known “Durand Line” used to be established, which nonetheless separates Afghanistan from Pakistan. It completely divided the Pashtun inhabitants within the north and, to a lesser extent, the Baloch inhabitants within the south.

The 3rd Anglo-Afghan Warfare, between Might and August 1919, introduced the Afghan venture to regain territorial regulate over the tribal areas. To begin with confined to the village of Bagh (within the Abbottabad area), this venture threatened to temporarily unfold to Peshawar the place Amanullah Khan, then ruling Afghanistan, was hoping for a well-liked rebellion.
The British regained intensive regulate of the border and bombarded Kabul, however, fearing additional stagnation after Global Warfare I, temporarily concluded the Rawalpindi Armistice Settlement on August 8, 1919, and amended it on November 22, 1921. They then identified Afghan sovereignty and prolonged Afghan sovereignty throughout the borders of Durren ter regulate. The preferred rise up in Waziristan (British aspect) did not anything: the frontier used to be now inviolable.
It survived the partition of India in 1947 in addition to the proclamation of the Republic of Pakistan in 1956 and won global popularity. From this painful historical past, two diametrically hostile understandings of the border will emerge.
For Afghanistan, “crossing the border”
From the Afghan viewpoint, Pakistan’s Federally Administered Pashtun Tribal Spaces, Federally Administered Tribal Spaces (FATA), grouped round seven “agencies” (Bajaur, Khyber, Kurram, Mohmand, Oraksai, North Waziristan and South Waziristan) and situated as of 2018 along the nationwide territory of Pakhtu Province and the Khyber Herbal Territory. are a compulsory passage at the Kabul-Jalalabad-Peshawar axis.

In spite of the period of the border, respectable crossings are uncommon, with transit of other people incessantly casual (reminiscent of Ghulam Khan in North Waziristan, Angoor Adda in South Waziristan or Karlachi in Kurram Company). There are few huge towns in Balochistan and the territories are reasonably arid: Chaman (in Pakistan), the neighboring the city of Spin Boldak (at the Afghan aspect, in Kandahar province) is the primary border publish within the space.
However it’s Torkham, within the north, within the Khyber Go, this is by means of a ways essentially the most frequented by means of vans and passengers. It’s due to this fact a very important business direction for Afghanistan. The realm is mountainous: the street is winding and standard caravans go within sight. Crossing the border by means of rail is now not allowed, the railway, now dilapidated, dates again to 1925.

In L’Utilization du monde (1963), the Genevan trip creator Nicolas Bouvier recounts his discuss with to those puts on December 5, 1954:
“After a 12 months and a part of trip I reached the foot of the go. The sunshine touched the foot of the Suleiman mountains and the Afghan customs fortress drowned in a mass of willows that glistened like husks within the solar. There have been no uniforms at the street blocked by means of a vibrant picket gate. I reached the place of job. I moved to the place of job. I moved to the place of job. smelled of thyme and buzzed with wasps. Sitting upright at the back of a bottle of crimson with paint, his eyes have been closed passport at the desk and I went to lunch.
Since then, and alongside the border, street delivery of products has taken position each day, with the Afghan financial system in particular depending on business with its neighbour.
For Pakistan, the “barrier border”
At the Pakistani aspect, the border used to be matter to larger controls and periodic closures (right through the breakdown of diplomatic members of the family between the 2 nations within the Sixties or right through the invasion of Afghanistan by means of the Soviet Union within the Eighties), in addition to transient re-opening (right through the primary takeover by means of the Taliban90 so long as the Taliban in A. the tricky barrier is satisfactory.
After Sept. 11, 2001, the Pakistani govt sought to forestall the infiltration of al-Qaeda and Taliban combatants fleeing the Western coalition offensive into its territory. All the way through 2003, then 2006-2007. and in 2008, bilateral diplomatic tensions accompanied by means of endemic conflicts ended in the transient closure of the strategic Chaman and Torkham border crossings, the established order of biometric controls and the development of portions of the obstacles managed by means of the army.
If the combat in opposition to terrorism used to be introduced as the primary function, for Islamabad it used to be additionally an issue of stopping drug trafficking and, in a much less glaring method, stemming the waft of displaced Afghans fleeing the struggle between the Western coalition and the Taliban, and even facilitating their compelled go back.
Following the withdrawal of Western troops from Afghanistan and the Taliban retaking energy in the summertime of 2021, tensions persevered to upward push till the declaration of “open war” by means of Khawaja Asif, Pakistan’s Minister of Protection, on February 26, 2026. In query, the Pakistani Taliban-T motion is supported by means of the Pakistani Taliban-T. Afghan Taliban and Islamic State terrorists in Khorasan, EI-Okay. A suicide assault claimed by means of the Islamic State (IS) and later attributed by means of Pakistan to the TTP and EI-Okay on February 6, 2026, centered the Shia mosque of Khadija Tul Kubra in Tarlai Kalan, southeast of Islamabad, leaving greater than thirty lifeless.
In retaliation, beginning on 21 February 2026, Pakistan bombed a number of places identified to harbor terrorist factions, in particular in Nangarhar province. After Afghanistan in flip attacked the border crossings, on February 26, 2026, Pakistan introduced Operation Ghazab Lil-Haq (“Righteous Fury”), which the next day to come, struck Kabul by means of air, in addition to Kandahar, the place of abode of the religious chief of the Taliban, Mullah Hayzadebat, Mullah Hayzadebat, Mullah Hayzabad. Paktia, Paktika or Laghman. Since then, the exchanges of fireside have now not stopped.
If the respectable goals are entrenched TTP camps, the United Countries Help Challenge in Afghanistan (MANUA) and non-governmental organizations (particularly Amnesty Global) have recorded a number of hundred lifeless (fighters and civilians) and 1000’s of displaced other people. Within the assault at the rehabilitation heart for drug addicts (at the territory of the previous Phoenix camp) in Kabul, on March 16, 2026, 143 other people died, along with the 76 civilian casualties already recorded in Afghanistan. The assault used to be reportedly performed based on the deaths of 4 civilians an afternoon previous in Bajaur district and a kid on March 8 in North Waziristan following mortar hearth from Afghanistan.
Chinese language mediation, opened in Urumqi (Xinjiang) in the beginning of April, after Qatar, Turkey and Saudi Arabia initiated it, hints at a imaginable discussion, in spite of the fragility of the location at the floor. In the meantime, this border war, with deep historic roots, continues to push Afghan civilians into the gravest humanitarian disaster they have got skilled because the Taliban’s go back to energy.
