Iran–Turkey relations
Iran–Turkey relations are the bilateral relations between the Islamic Republic of Iran and the Republic of Turkey. The two states have a complex relationship, by competing over influence in Syria and the Caucasus through supporting opposing proxies as part of a proxy conflict. However, both countries also have some shared interests, as both are trade and economic partners. Their relationship is centuries old, dating to the 16th century when Sunni Ottoman Empire and the Shia Safavid empire fought each other for centuries. The two countries are also major trade partners and are perceived as mutually interdependent due to geographical proximity as well as historically shared cultural, linguistic, and ethnic traits.
Historically, the region has shared empires and conquests by the Achaemenids, Parthians, Macedonians, Seljuks, the Mongols and the Timurids.
Iran and Turkey have long been at odds over conflicts such as those in Syria, Libya, and the South Caucasus. However, they also have shared common interests in some instances, such as the issue of Kurdish separatism and the Qatar diplomatic crisis.
Turkey has an embassy in Tehran and consulates in Mashhad, Tabriz and Urmia, while Iran has an embassy in Ankara and consulates in Istanbul, Erzurum and Trabzon.
History
Numerous times throughout the millennia-long history shared by the two neighboring nations, parts of the territory of Anatolia were conquered by the various empires based in modern-day Iran, including the Median Empire, the Achaemenid Empire, the Parthian Empire, the Sasanian Empire, the Safavid Iran, and the Afsharid Iran, amongst others. In ancient times, the Asia Minor formed one of the core regions of the Achaemenid Empire, with the cities of Sardis and Smyrna in western Anatolia being the most notable. Iğdır Province, in what is now Eastern Anatolia, formed part of Qajar Iran up to the outcome of the Russo-Persian War and the ratified Treaty of Turkmenchay.Turks and Iranians share a common cultural heritage, known as the Turco-Persian tradition, which was a prominent characteristic of the Ghaznavid, Seljuk, Sultanate of Rum, Ottoman, Timurid, Qara Qoyunlu, Aq Qoyunlu, and Safavid Empires.
The Ottomans frequently imposed trade embargoes on the Safavid Empire to assert dominance over their eastern rival. Following the Ottoman victory at Chaldiran in 1514 and subsequent territorial gains, Selim I restricted trade routes for Safavid silk merchants and ordered the arrest of those entering Ottoman territory from Safavid lands. These measures, including the detention of Safavid-associated intellectuals, were lifted under Suleiman the Magnificent. A renewed embargo in 1603 was aimed at countering the resurgence of Safavid power, was less effective.

The Ottoman-Iranian wars, lasting from the late 18th to the mid-19th century, were caused in part by sectarian tensions between Sunni Ottomans and Shia Iranians, territorial disputes, and competition over trade routes. The war of 1789 centered on the strategic Mount Ararat, where both empires sought to assert control. Iran's military offensives often targeted Ottoman fortifications, but the Ottomans, adopting defensive strategies, managed to repel these efforts. The Iranians and Ottomans clashed in 1789, 1821–1823, and 1830–1833. The Ottoman Empire won every war, defeating the Iranians. In the war of 1821-23, the Ottomans were led by Hafiz Ismail Pasha. solidifying its dominance in the region.
The period between 1789 and 1876 saw significant rivalry between the Ottoman Empire and Iran, particularly in their efforts to assert dominance in the region. Territorial disputes were a recurring source of conflict, exemplified by the Gok Tepe War, which concluded with Iran's significant territorial losses under the Treaty of Gulistan. Following Iranian defeat, Iran reapproached the Ottomans in order to counter Russia.
Iran's intelligence network also included the monitoring of Iranian minorities within Ottoman territories, aiming to protect their interests and undermine Ottoman authority. Information gathered through espionage was leveraged to strengthen Iran's defensive strategies and occasionally used in collaboration with European powers to counter Ottoman influence.
The Treaty of Kasr-i Shirin in 1876 officially ended the wars, but there were still border disputes between the countries. Issues such as the ownership of Mount Ararat remained a source of tension well into the 20th century. According to Qayum, the Ottoman-Iranian wars still influence contemporary regional rivalries. According to Qayum the modern day cases of Syria and Iraq are examples of where sectarian and political divisions between contemporary Iran and Turkey, echo the historic tensions between the former empires.
20th century
On 22 April 1926, the First "Treaty of Friendship" between Iran and Turkey was signed in Tehran. The basic principles included friendship, neutrality and non-aggression towards each other. The agreement also included possible joint action against groups who would try to disturb peace and security or who would try to overthrow either country's government. This policy was indirectly aimed at the internal problems both countries had with their Kurdish minorities.On 23 January 1932, the first definitive frontier treaty between Turkey and Iran was signed in Tehran. The border between Turkey and Iran is one of the oldest in the world and has stayed more or less the same since the Battle of Chaldiran in 1514, and the Treaty of Zuhab. The 1932 treaty thus formalized a centuries-old status quo. On the same day, the countries signed a new Treaty of Friendship, as well as a Treaty of Conciliation, Judicial Settlement and Arbitration.

Between 16 June and 2 July 1934, Reza Shah Pahlavi visited Turkey with several high-ranking officials, including General Hasan Arfa. Several regions in Turkey were visited and attempts at close friendship and cooperation between the two leaders were made. Reza Shah was reportedly impressed by the republic's modernization reforms and he saw this as an example for his own country.
On 8 July 1937, a non-aggression pact was signed between Turkey, Iran, Iraq and Afghanistan, which later became known as the Treaty of Saadabad. The purpose of this agreement was to ensure security and peace in the Middle East.
In August 1955, the Central Treaty Organization, a mutual security pact between Iran, Turkey, Iraq, Pakistan and Britain was established.
In July 1964, the Regional Cooperation for Development, aimed at joint economic projects between Iran, Turkey and Pakistan, was established.
In 1964, Ruhollah Khomeini was sent to exile in Bursa and he stayed there for eleven months. On 5 September 1965, Khomeini left Turkey and went to Najaf in Iraq.
A period of coldness passed after the 1979 Iranian Revolution which caused major changes in Iran and the Middle Eastern status quo. Today, Iran and Turkey closely cooperate in a wide variety of fields, such as fighting terrorism, drug trafficking, and promoting stability in Iraq and Central Asia. However, the two countries have competed for influence since the 1990s; this has been escalating since the 2010s in various fronts across MENA and South Asia.
Iranian nuclear program
In May 2010, Turkish Prime Minister Recep Tayyip Erdogan made an unscheduled trip to Tehran in coordination with Brazilian President Lula da Silva to make an agreement to outsource Iranian uranium enrichment to his country to avoid further sanctions on Iran.The decision of Turkey to host a radar system to track missiles launched from Iran has been seen by the Iranians as a serious break in relations.
In a 2012 Pew Research Global Attitudes Survey, 54% of Turks oppose Iran's acquisition of nuclear weapons, 46% consider a nuclear-armed Iran somewhat of a threat and 26% support the use of military force to prevent Iran from developing nuclear weapons. 37% of Turks believe that Iran is a minor threat/no threat at all, the lowest percentage between surveyed countries in MENA region. But only 34% of Turkey's population approves of tougher sanctions on Iran, compared to 52% of Turks disapproving of sanctions.
NATO missile shield crisis
Turkey, the largest NATO member in the region, hosted the establishment of a NATO missile shield in September 2011 which has caused a crisis between Turkey and Iran. Iran claimed that the missile shield is a US plot to protect Israel from any counter-attack should Israel target Iran's nuclear facilities. In addition, Ayatollah Ali Khamenei stated that Turkey should rethink its policies over Syria, the missile shield, and promotion of secularism over the Arab world following the Arab Spring.Iranian Major General Yahya Rahim Safavi also expressed his opinion over the situation: "the behaviour of Turkish statesmen towards Syria and Iran is wrong and, I believe, they are acting in line with the goals of America," adding that "if Turkey does not distance itself from this unconventional political behavior it will have both the Turkish people turning away from it domestically and the neighboring countries of Syria, Iraq and Iran reassessing their political ties."
Turkey stated that the NATO missile system neither causes a threat or targets any particular nation. Turkish Minister of National Defense, İsmet Yılmaz, insisted that the system's aim is to secure Europe, as well as for the security of Turkey.
On 23 October 2011, US Secretary of State Hillary Clinton warned Iran over the United States' presence in Turkey, saying that "Iran would be badly miscalculating if they did not look at the entire region and all of our presence in many countries, both in bases and in training with NATO allies, like Turkey.”
In November 2011, the head of the Revolutionary Guard's aerospace division threatened to strike Turkey if other countries attacked Iran.
