Iran–Turkey border

The Iran–Turkey border ( fa, ; tr, İran–Türkiye sınırı) is in length, and runs from the tripoint with Azerbaijan in the north to the tripoint with Iraq in the south.

Description

The border starts in the north at the tripoint with Azerbaijan's Nakhchivan Autonomous Republic on the Aras river. The border then proceeds to the north-west along the Karasu Çayı river, thereby granting Turkey a sliver of territory linking it to Azerbaijan. The border then proceeds south-west and then south via a series of irregular overland lines, down to the Iraqi tripoint. The border region is extremely mountainous and is populated mostly by Kurds on both sides.

History

Ottoman era (1500s–1920)

The Ottoman Empire had conquered much of what is now Iraq from Safavid Persia in the Ottoman–Safavid War of 1532–1555. The war concluded with the Peace of Amasya, by which Ottoman rule over the region was confirmed. Ottoman control of Mesopotamia and eastern Turkey was confirmed following the Ottoman–Safavid War (1623–1639), which was ended by the Treaty of Zuhab. The Zuhab treaty stipulated that the boundary between the two empires would run between the Zagros Mountains and the Tigris River, though a precise lines was not drawn at that time.

During the Ottoman–Hotaki War (1722–1727) the Ottomans invaded Iran in league with Russia, gaining large parts of north-west Iran via the Treaty of Hamedan. Another war followed in the 1740s which was ended by the Treaty of Kerden in 1746, which restored Iran's western provinces and re-affirmed the 1639 Zuhab border.

The Ottoman–Persian War (1821–1823) ended with the signing of the First Treaty of Erzurum, which re-affirmed the 1639 Zuhab border. A boundary commission involving Iranian, Ottoman, Russian and British officials assisted with the boundary delimitation, resulting in the Second Treaty of Erzurum of 1847 which affirmed the 1639 border with some small modifications. The four-way boundary commission resumed its work in the following years, and after much work and cartographic disputation a detailed map was produced in 1869. Some small modification were made in the vicinity of Qotur as a result of the Treaty of Berlin (1878).

Despite the work of the commission, disputes concerning the precise boundary alignment continued. The Ottomans and Iran agreed to work on a more precise demarcation in 1911 at the urging of Russia and the Britain, both of whom had colonial aspirations in the region. From November 1913-October 1914 a boundary commission established the Constantinople Protocol, providing a detailed delimitation of the entire boundary. The four-nation boundary commission then surveyed the border on the ground and demarcated it with pillars (excluding the Qotur area which remained in dispute), producing a detailed series of map depicting the confirmed frontier.

Post–Ottoman era (1920–present)

During the First World War an Arab Revolt, supported by Britain, succeeded in removing the Ottomans from most of the Middle East. As a result of the secret 1916 Anglo-French Sykes-Picot Agreement Britain gained control of the Ottoman Vilayets of Mosul, Baghdad and Basra, which it organised into the mandate of Iraq in 1920.

By the 1920 Treaty of Sèvres Anatolian Turkey was to be partitioned, with the areas north of the Mosul Vilayet to be included within an autonomous or independent Kurdish state. Turkish nationalists were outraged at the treaty, contributing to the outbreak the Turkish War of Independence; the Turkish success in this conflict rendered Sèvres obsolete. By the 1923 Treaty of Lausanne Turkey's independence was recognised and a far more generous territorial settlement was agreed upon, albeit at the cost of Turkey formally renouncing any claim to Arab lands. In the east the former Ottoman-Iran boundary was retained, now forming the borders between Iran and Iraq, and also Iran and the new Republic of Turkey.

On 9 April 1929 a treaty was signed in Ankara between Turkey and Iran to further delimit their border, partly in response to the Kurdish Ararat rebellion; this was then finalised at the 1932 Tehran Convention, resulting in some small exchanges of territory in the vicinity of Little Ararat, Bazhergah and Qotur. The border was then demarcated and a final agreement signed in Tehran on 26 May 1937.

Crossings

There are three crossings along the entire border, two for vehicular traffic and one for vehicular and rail traffic. The busiest of three, Gürbulak, is among the busiest border checkpoints in the world.

Barrier

The Turkish government has expanded its plans to build a concrete wall along the Iranian border to cover the entirety of the frontier of , Van Governor Mehmet Emin Bilmez said on July 27, 2021.

The wall is high, and patrols have been reinforced in the light of the 2021 Fall of Afghanistan to Taliban.

Illegal crossings

With the 2021 fall of Afghanistan, a wave of refugees have been crossing Iran, then into Turkey. Both economic migrants looking for job opportunities and refugees fleeing Taliban violence or extorsions have been reported. Turkish border police have raised their efforts, violently massing those refugees at the border, pushing back into Iran, arresting them when they crossed, and deporting them without due process. Evidence of special efforts to prevent reporters from documenting this issue have been reported.
