:Ottoman–Persian War (1821–1823)

Tensions between the two empires had been rising due to the Ottoman Empire's harboring of rebellious tribesmen from the Iranian Azerbaijan Province.{{sfn|Tucker|2010|p=1140}} The issues concerning the Kurdish borderland tribes such as the Haydaran and Sipki tribes had complicated the relations between the two empires. For instance, Iran launched a military campaign against Dervish Pasha, the muhafiz of Van, when he refused to return the Sipki Kurdish who took refuge and settled in Archesh.{{sfn|Ateş|2013|p=49}}

The Ottoman-Iranian War that began in 1821 was also part of a series of wars between the two empires, which was attributed to the influences of foreign powers, particularly Great Britain and the Russian Empire.{{sfn|Sorkhabi|2017|p=43-44}} The Iranians and the Ottomans were within their respective spheres of influence and were drawn to their rivalry. The Russian Empire was attempting to put pressure on the Ottoman Empire, which was then at war with the Greeks.{{sfn|Tucker|2010|p=1140}}

Crown Prince Abbas Mirza of Iran, at the instigation of the Russian Empire, invaded Western Armenia and the areas surrounding the Iranian province of Azerbaijan.{{sfn|Tucker|2010|p=1140}} On 10 September 1821, the Iranian forces marched out of Tabriz towards the border.{{Cite thesis|title=The grand strategy of the Russian Empire in the Caucasus against its southern rivals (1821-1833)|url=http://etheses.lse.ac.uk/3512/|publisher=The London School of Economics and Political Science (LSE)|date=October 2016|degree=phd|language=en|first=Serkan|last=Keçeci}} On 16 September, Iranian forces crossed the border at Gürbulak and stormed the Bayezid Fortress in November 1821, securing Iranian supply routes. As the Iranian army marched into the region, they went after the Heydaran tribesmen, who would flee to Diyarbakir.{{Cite thesis |title=Fragile alliances in the Ottoman East: the Heyderan Tribe and the empire, 1820 - 1929 |url=http://hdl.handle.net/11693/46654 |publisher=Bilkent University |date=April 2018 |language=English |first=Erdal |last=Çiftçi|hdl=11693/46654 }}

After Abbas Mirza's successful winter campaign, he withdrew most of his forces to Tabriz while leaving garrisons in significant towns and cities.{{Cite book |url=http://worldcat.org/oclc/1294638373 |title=War and peace in Qajar Persia: Implications Past and Present |date=30 January 2008 |isbn=978-1-134-10307-2 |editor-last=Farmanfarmaian |editor-first=Roxane |oclc=1294638373}} The Turks began to organize a counterattack, organized under the new serasker, Mohammad Amin Rauf Pasha. They planned to steamroll the garrisons in Eastern Anatolia and occupy parts of Azerbaijan to prevent Iran from gathering their troops, and force a peace on Ottoman terms. However, the fortress of Toprah Kaleh stood in the way of Ottoman plans due to its strategic location. The Sardar of Erevan kept raiding Ottoman positions around Toprah Kaleh, allowing Abbas Mirza precious time to recover forces to relieve the fortress. The resulting battle in May 1822 was a defeat for the Ottomans, but the Iranians were unable to take advantage of their success.

A second counter attacked was organized by the Ottoman "wali" (governor) of Baghdad, Dawud Pasha, who invaded Iran. The invasion was unsuccessful and he was pursued by the Qajar army under the lead of the Shah's oldest son, prince Mohammad Ali Mirza.{{cite web |last= |first= |title=Turko–Iranian War (1821–1823) |work=Cengage Group |via=Encyclopedia.com |access-date=2025-03-02 |url=https://www.encyclopedia.com/humanities/encyclopedias-almanacs-transcripts-and-maps/turko-iranian-war-1821-1823 }} The Ottomans retreated back to their own territory, while the Iranians took Shahrezur along the Sirvan River, supported by Feili Kurds and Lurs who defeated the Ottoman opposition and forced them to further retreat to Kirkuk.{{cite book |last=Farrokh |first=Kaveh |title=Iran At War 1500-1988 |publisher=Osprey Publishing |year=2011 |page=204 |url=https://archive.org/details/ogm-iran-at-war-1500-1988/page/204/mode/2up?q=1821 }} Mohammad Ali Mirza conquered Sulayméniyah and following the capture of Samarra, besieged Baghdad with 40,000 infantry and artillery. The Ottoman retreat ended here, as Dawud Pasha successfully defended the city with 3,900 infantry and 8,800 cavalry, preventing the Qajars from taking strategically important Baghdad. Combined with the effects of a cholera outbreak, Mohammad Ali Mirza was ultimately forced to lift the siege.Azap, Eralp Yaşar. “The Epidemic that Emerged during the 1820-1823 Ottoman-Iran War and Its Impact on the War.” Hazine-I Evrak Arşiv ve Tarih Araştırmaları Dergisi 2, no. 2 (December 2020): 84-88Al-Bustani, 1979, p. 65Azap, E.

Mohammad Ali Mirza himself caught the disease during the siege, and died on November 22, while in Ctesiphon.{{cite book |last=Hambly |first=Gavin R.

Meanwhile, Abbas Mirza marched into eastern Anatolia with 30,000 troops and met an Ottoman army of 50,000 at the Battle of Erzurum.{{when|date=March 2025|reason=When exactly did the battle take place?}} Abbas Mirza scored a crushing victory over the Ottomans despite being severely outnumbered and his army suffering from a cholera epidemic.{{sfn|Tucker|2010|p=1140}}

Peace was not concluded until the Treaty of Erzurum two years later;{{sfn|Williamson|2008|p=108}} both sides recognized the previous borders established by the Treaty of Zuhab in 1639,{{sfn|Mikaberidze|2011|p=301}} with no territorial changes. Also included in the treaty, was the guaranteed access for Persian pilgrims to the holy sites of Mecca and Medina within the Ottoman Empire.{{sfn|Tucker|2010|p=1140}}
