Qajar Iran in the context of "Reuter concession"

Azerbaijan, officially the Republic of Azerbaijan, is a transcontinental and landlocked country at the boundary of Western Asia and Eastern Europe. It is a part of the South Caucasus region and is bounded by the Caspian Sea to the east, Russia's republic of Dagestan to the north, Georgia to the northwest, Armenia and Turkey to the west, and Iran to the south. Baku is the capital and largest city.

The territory of what is now Azerbaijan was ruled first by Caucasian Albania and later by various Persian empires. Until the 19th century, it remained part of Qajar Iran, but the Russo-Persian wars of 1804–1813 and 1826–1828 forced the Qajar Empire to cede its Caucasian territories to the Russian Empire; the treaties of Gulistan in 1813 and Turkmenchay in 1828 defined the border between Russia and Iran. The region north of the Aras was part of Iran until it was conquered by Russia in the 19th century, where it was administered as part of the Caucasus Viceroyalty.

Khan (/xɑːn/, /kɑːn/, /kæn/) is a historic Turkic and Mongolic title originating among nomadic tribes in the Central and Eastern Eurasian Steppe to refer to a king. It first appears among the Rouran and then the Göktürks as a variant of khagan (sovereign, emperor) and implied a subordinate ruler. In the Seljük Empire, it was the highest noble title, ranking above malik (king) and emir (prince). In the Mongol Empire it signified the ruler of a horde (ulus), while the ruler of all the Mongols was the khagan or great khan. It is a title commonly used to signify the head of a Pashtun tribe or clan.

The title subsequently declined in importance. During the Safavid and Qajar dynasty it was the title of an army general high noble rank who was ruling a province, and in Mughal India it was a high noble rank restricted to courtiers. After the downfall of the Mughals it was used promiscuously and became a surname. Khan and its female forms occur in many personal names, generally without any nobiliary of political relevance, although it remains a common part of noble names as well.

The Russo-Persian War of 1804–1813 was one of the many wars between the Persian Empire and Imperial Russia, and, like many of their other conflicts, began as a territorial dispute. The new Persian king, Fath Ali Shah Qajar, wanted to consolidate the northernmost reaches of his kingdom—modern-day Georgia—which had been annexed by Tsar Paul I several years after the Russo-Persian War of 1796. Like his Persian counterpart, the Tsar Alexander I was also new to the throne and equally determined to control the disputed territories.

The war ended in 1813 with the Treaty of Gulistan which ceded the previously disputed territory of Georgia to Imperial Russia, and also the undisputed Iranian territories of Dagestan, most of what is modern Azerbaijan, and minor parts of Armenia.

The Russo-Persian War of 1826–1828 was the last major military conflict between the Russian Empire and Qajar Iran, which was fought over territorial disputes in the South Caucasus region.

Initiated by Russian expansionist aims and intensified by Iranian resistance, the war witnessed significant military engagements, including the Battle of Ganja and Capture of Erivan. The Iranians were initially successful, catching the Russian forces of Yermolov off-guard. They were aided by local uprisings against Russian garrisons in Talish, Ganja, Shirvan, Shakki, and other areas. However Russian reinforcements under the newly appointed General Ivan Paskevich turned the war decisively in Russia's favor, capturing the important city of Tabriz in northwestern Iran.

The Treaty of Gulistan (also spelled Golestan: Russian: Гюлистанский договор, romanized: Gyulistanskiy dogovor; Persian: عهدنامه گلستان, romanized: Ahdnāme-ye Golestān) was a peace treaty concluded between the Russian Empire and Qajar Iran on 24 October 1813 in the village of Gulistan (now in the Goranboy District of Azerbaijan) as a result of the first full-scale Russo-Persian War (1804 to 1813). The peace negotiations were precipitated by the successful storming of Lankaran by General Pyotr Kotlyarevsky on 1 January 1813. It was the first of a series of treaties (the last being the Akhal Treaty) signed between Qajar Iran and Imperial Russia that forced Persia to cede the territories that formerly were part of Iran.

The treaty confirmed the ceding and inclusion of what is now Dagestan, eastern Georgia, most of the Republic of Azerbaijan, and parts of northern Armenia from Iran into the Russian Empire.

The Treaty of Turkmenchay was an agreement between Qajar Iran and the Russian Empire, which concluded the Russo-Persian War (1826–1828). It was second of the series of treaties (the first was the 1813 Treaty of Gulistan and the last, the 1881 Treaty of Akhal) signed between Qajar Iran and Imperial Russia that forced Iran to cede or recognize Russian influence over the territories that formerly were part of Iran.

The treaty was signed on 22 February 1828 (5 Sha'ban 1243) in Torkamanchay (a village between Tabriz and Tehran). It made Iran cede the control of several areas in the South Caucasus to Russia: the Erivan Khanate, the Nakhchivan Khanate and the remainder of the Talysh Khanate. The boundary between Russia and Iran was set at the Aras River. These territories are now Armenia, the south of the Republic of Azerbaijan, Nakhchivan and Iğdır Province (now part of Turkey).

The Great Game was a rivalry between the 19th-century British and Russian empires over influence in Central Asia, primarily in Afghanistan, Persia, and Tibet. The colonial empire and great land power (heartland state) used military interventions and diplomatic negotiations to acquire and redefine territories in Central and South Asia. Russia conquered Turkestan, and Britain expanded and set the borders of British India. By the early 20th century, a line of independent states, tribes, and monarchies from the shore of the Caspian Sea to the Eastern Himalayas were made into protectorates and territories of the two empires.

Though the Great Game was marked by distrust, diplomatic intrigue, and regional wars, it never erupted into a full-scale war directly between Russian and British colonial forces. However, the two nations battled in the Crimean War from 1853 to 1856, which affected the Great Game. The Russian and British Empires also cooperated numerous times during the Great Game, including many treaties and the Afghan Boundary Commission.

The Parsis or Parsees (/ˈpɑːrsiz/) are a Zoroastrian ethnic group in the Indian subcontinent. They are descended from Persian refugees who migrated to the Indian subcontinent during and after the Arab-Islamic conquest of Iran in the 7th century, when Zoroastrians were persecuted by the early Muslims. Representing the elder of the Indian subcontinent's two Zoroastrian communities, the Parsi people are culturally, linguistically, and socially distinct from the Iranis, whose Zoroastrian ancestors migrated to British-ruled India from Qajar-era Iran. The word Parsi is derived from the Persian language, and literally translates to Persian (پارسی, Pārsi).

According to the 16th-century Parsi epic Qissa-i Sanjan, fleeing persecution, the Zarthushti (Zoroastrian) Persians, citizens of the Sassanian empire sought refuge in the Indian subcontinent. This migration from different parts of the Sassanian empire continued between the 8th century and the 10th century. The earliest of these migrants settled among the Hindus of present-day Gujarat after being granted refuge by Rajput King Jadhav Rana, the king of Sanjan.
