Treaty of Gulistan in the context of "Treaty of Turkmenchay"

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.

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.

Azerbaijanis (/ˌæzərbaɪˈdʒæni, -ɑːni/; Azerbaijani: Azərbaycanlılar, آذربایجانلیلار), Azeris or Azerbaijani Turks (Azərbaycan türkləri, آذربایجان تۆرکلری) are a Turkic ethnic group living mainly in the Azerbaijan region of northwestern Iran and the Republic of Azerbaijan. They are predominantly Shia Muslims. They comprise the largest ethnic group in the Republic of Azerbaijan and the second-largest ethnic group in neighboring Iran and Georgia. They speak the Azerbaijani language, belonging to the Oghuz branch of the Turkic languages.

Following the Russo-Persian Wars of 1813 and 1828, the territories of Qajar Iran in the Caucasus were ceded to the Russian Empire and the treaties of Gulistan in 1813 and Turkmenchay in 1828 finalized the borders between Russia and Iran. After more than 80 years of being under the Russian Empire in the Caucasus, the Azerbaijan Democratic Republic was established in 1918 which defined the territory of the Republic of Azerbaijan.

Fath-Ali Shah Qajar (Persian: فتحعلى‌شاه قاجار, romanized: Fatḥ-ʻAli Šâh Qâjâr; 5 August 1772 – 24 October 1834) was the second Shah of Qajar Iran. He reigned from 17 June 1797 until his death on 24 October 1834. His reign saw the irrevocable ceding of Iran's northern territories in the Caucasus, comprising what is nowadays Georgia, Dagestan, Azerbaijan, and Armenia, to the Russian Empire following the Russo-Persian Wars of 1804–1813 and 1826–1828 and the resulting treaties of Gulistan and Turkmenchay. These two treaties are closely tied to Fath-Ali Shah's legacy amongst Iranians, who often view him as a weak ruler.

Fath-Ali Shah successfully restructured a mostly Turkic tribal khanship into a centralized and stable monarchy based on the old imperial design. This brought to Iran a relatively calm and prosperous period, secured a mutually beneficial relationship between state and religion, established foundational principles of state administration, and supported cultural and artistic revival which remained a distinctive feature of the Qajar dynasty. At the end of his reign, his mounting economic problems and declining military power took Iran to the verge of ruin, the situation was made worse by the subsequent struggle for the throne which ensued after his death.

Derbent, also historically known as Darband, or Derbend, is the southernmost city in Russia. It is situated along the southeastern coast of the Republic of Dagestan, occupying the narrow gateway between the Caspian Sea and the Caucasus Mountains, and connecting the Eurasian Steppe to the north and the Iranian Plateau to the south. Derbent covers an area of 69.63 square kilometres (26.88 sq mi) with a population of roughly 120,000 residents.

Derbent is considered the oldest city in Russia, with historical documentation dating to the 8th century BC, making it one of the oldest continuously inhabited cities in the world. Due to its strategic location, over the course of history, the city changed ownership many times, particularly among the Persian, Arab, Mongol, Timurid, and Shirvan kingdoms. In the early 19th century, the city came under control of the Russian Empire through the Treaty of Gulistan signed with Qajar Iran.

The Battle of Ganja or Elisavetpol (also Elizabethpol, Yelisavetpol, &c.) took place on 25 September 1826/13 September 1826, during the Russo-Persian War of 1826–1828.

Crown prince and commander-in-chief Abbas Mirza had launched a successful campaign in the summer of 1826, which resulted in the recapture of many of the territories that were lost to the Russians by virtue of the Treaty of Gulistan (1813). Noticing the approach of the Iranian army, many of the locals that had recently come under formal Russian jurisdiction, quickly switched sides. Amongst the swiftly recaptured territories by the Iranians were the important cities of Baku, Lankaran and Quba.
