Nader Shah in the context of "Ahmad Shah Durrani"

The Durrani Empire, colloquially known as the Kingdom of Afghanistan, Afghan Empire or the Sadozai Kingdom, was an Afghan empire founded by the Durrani tribe of Pashtuns under Ahmad Shah Durrani in 1747, which spanned parts of Central Asia, the Iranian plateau, and the Indian subcontinent. At its peak, it ruled over present-day Afghanistan, much of Pakistan, parts of northeastern and southeastern Iran, eastern Turkmenistan, and northwestern India. Next to the Ottoman Empire, the Durrani Empire is considered to be among the most significant Islamic empires of the second half of the 18th century.

Ahmad was the son of Muhammad Zaman Khan (an Afghan chieftain of the Abdali tribe) and the commander of Nader Shah Afshar. Following Afshar's death in June 1747, Ahmad secured Afghanistan by taking Kandahar, Ghazni, Kabul, and Peshawar. After his accession as the nation's king, he changed his tribal name from Abdali to Durrani. In 1749, the Mughal Empire had ceded sovereignty over much of northwestern India to the Afghans; Ahmad then set out westward to take possession of Mashhad, which was ruled by the Afsharid dynasty under Shahrokh Shah, who also acknowledged Afghan suzerainty. Subsequently, Ahmad sent an army to subdue the areas north of the Hindu Kush down to the Amu Darya, and in short order, all of the different Afghan tribes began to join his cause. Under Ahmad, the Afghans invaded India on eight occasions, subjugating parts of Kashmir and the majority of Punjab. In early 1757, he sacked Delhi, but permitted Mughal emperor Alamgir II to remain in nominal control as long as he acknowledged Afghan suzerainty over the regions south of the Indus River, till Sutlej river.

Lahore is the capital and largest city of the Pakistani province of Punjab. It is the second-largest city in Pakistan, after Karachi, and 27th largest in the world, with a population of over 14 million. Lahore is one of Pakistan's major industrial, educational and economic hubs. It has been the historic capital and cultural centre of the wider Punjab region, and is one of Pakistan's most socially liberal, progressive, and cosmopolitan cities.

Lahore's origin dates back to antiquity. The city has been inhabited for around two millennia, although it rose to prominence in the late 10th century with the establishment of the Walled City, its fortified interior. Lahore served as the capital of several empires during the mediaeval era, including the Hindu Shahis, Ghaznavid Empire and Delhi Sultanate. It reached the height of its splendour under the Mughal Empire between the late 16th and early 18th centuries, being its capital city for many years. During this period, it was one of the largest cities in the world. The city was captured by the forces of the Afsharid ruler Nader Shah in 1739. Although the Mughal authority was re-established, it fell into a period of decay while being contested among the Afghans and the Sikhs between 1748 and 1798, eventually becoming capital of the Sikh Empire in the early 19th century. Lahore was annexed to the British Raj in 1849 and became the capital of British Punjab. Lahore was central to the independence movements of British India, with the city being the site of both the Declaration of Indian Independence and the resolution calling for the establishment of Pakistan. It experienced some of the worst rioting during the partition of British India preceding Pakistan's establishment. Following the success of the Pakistan Movement and the subsequent partition in 1947, Lahore was declared the capital of Pakistan's Punjab province.

The sack of Delhi occurred from 28 January to 22 February 1757, carried out by the Durrani Empire under the Afghan king Ahmad Shah Durrani. Delhi, the capital of the Mughal Empire, experienced multiple invasions by the Afghans during the 18th century.

The decline of the Mughal Empire began with the death of Emperor Aurangzeb on 3 March 1707. The Mughals faced numerous invasions from the Maratha Confederacy and internal conflicts over succession. The Mughals continued declining under Muhammad Shah, allowing adventurers such as Nader Shah to invade Mughal territories and sack Delhi. Following Nader Shah's death, his eastern domains were taken over by Ahmad Shah Durrani, who formed the Durrani Empire and centered his power base in Kandahar, Afghanistan. After three invasions by the Afghans, the Mughals lost numerous territories including Kashmir, Punjab, and Sindh.

The Khanate of Bukhara was an Uzbek monarchy in Central Asia from 1501 to 1785, founded by the Shaybanid dynasty, a branch of the Abu'l-Khayrids. Muhammad Shaybani, grandson of the steppe ruler Abu'l Khayr Khan, conquered the major cities of Mawarannahr (Transoxiana) — Balkh, Bukhara, Samarkand, and Tashkent — and established his rule in the region. In its earliest years, the Khanate was alternately governed from each of these cities before Abdullah Khan II (r. 1557–1598) established Bukhara as its permanent capital by 1562.

In the 17th and 18th centuries, the Khanate was ruled by the Janid dynasty (also referred to as Ashtarkhanids or Toqay Timurids). They were the last Chingissid dynasty to rule Bukhara. In 1740, it was conquered by Nader Shah, the Shah of Iran. After his death in 1747, the Khanate was controlled by the non-Chingissid descendants of the Uzbek emir Khudayar Bi, through the prime ministerial position of ataliq. In 1785, his descendant, Shah Murad, formalized the family's dynastic rule (Manghit dynasty), and the Khanate became the Emirate of Bukhara. The Manghits were non-Chingissid and took the Islamic title of emir instead of khan since their legitimacy was not based on descent from Genghis Khan.

Afshar (Azerbaijani: Əfşar افشار; Turkish: Avşar, Afşar; Turkmen: Owşar اوْوشار; Persian: افشار, romanized: Afshār) is a tribe of Oghuz Turkic origin that split into several groups in Iran, Turkey and Afghanistan.

Afshar means "obedient". According to Rashid-al-Din Hamadani, Afshar, the eponymous founder of the tribe, was a son of Yildiz Khan, the third son of Oghuz Khan. During the Seljuk conquests of the 11th century, they moved from Central Asia into the Middle East. They are noted in history for being one of the Qizilbash tribes that helped establish the Safavid and later the Afsharid dynasty of Iran. Nader Shah, who became the monarch of Iran in 1736, was from the Qereklu clan (Persian: قرخلو) of Afshars. The founders of the Germiyanids, and the Khalkhal Khanate were also of Afshar descent. The founder of the Karamanids may have also been of Afshar descent.

Heraclius II, also known as Erekle II (Georgian: ერეკლე II) and The Little Kakhetian (Georgian: პატარა კახი [pʼatʼaɾa kʼaχi]; 7 November 1720 or 7 October 1721 [according to C. Toumanoff] – 11 January 1798), of the Bagrationi dynasty, was the king (mepe) of the Kingdom of Kakheti from 1744 to 1762, and of the Kingdom of Kartli-Kakheti from 1762 until his death in 1798. In the contemporary Persian sources he is referred to as Erekli Khan (ارکلی خان), while Russians knew him as Irakly (Ираклий). Heraclius is the Latinized form of his name.

From being granted the kingship of Kakheti by his overlord Nader Shah in 1744 as a reward for his loyalty, to becoming the penultimate king of the united kingdoms of Kakheti and Kartli in eastern Georgia, his reign is regarded as the swan song of the Georgian monarchy. Aided by his personal abilities and the unrest in Iran following Nader Shah's death, Heraclius established himself as a de facto autonomous ruler, unified eastern Georgia politically for the first time in three centuries, and attempted to modernize the government, economy, and military. Overwhelmed by the internal and external menaces to Georgia's precarious independence and its temporary hegemony in eastern Transcaucasia, he placed his kingdom under the formal Russian protection in 1783, but the move did not prevent Georgia from being devastated by the Persian invasion in 1795. Heraclius died in 1798, leaving the throne to his moribund heir, George XII.

The Kingdom of Kartli-Kakheti (Georgian: ქართლ-კახეთის სამეფო, romanized: kartl-k'akhetis samepo) was created in 1762 by the unification of the two eastern Georgian kingdoms of Kartli and Kakheti. From the early 16th century, according to the 1555 Peace of Amasya, these two kingdoms were under Iranian control. In 1744, Nader Shah granted the kingship of Kartli to Teimuraz II and that of Kakheti to his son Heraclius II, as a reward for their loyalty. When Nader Shah died in 1747, Teimuraz II and Heraclius II capitalized on the instability in Iran proper, and declared de facto independence. After Teimuraz II died in 1762, Heraclius succeeded him as ruler of Kartli, thus unifying the two kingdoms.

Heraclius was able, after centuries of Iranian suzerainty over Georgia, to guarantee the autonomy of his kingdom throughout the chaos that had erupted following Nader Shah's death. He became the new Georgian king of a politically united eastern Georgia for the first time in three centuries. Though Heraclius tendered his de jure submission to the newly established Zand dynasty quickly after the unification in 1762, the kingdom remained de facto autonomous for the next three decades to come. In 1783, Heraclius signed the Treaty of Georgievsk with the Russian Empire, by which he formally laid Kartli-Kakheti's investiture in the hands of the Russian monarch, and made the kingdom a Russian protectorate. Amongst others, this provided the nominal guarantee for protection against new Iranian attempts, or by any others, to (re)conquer or attack eastern Georgia. By the 1790s, a new strong Iranian dynasty, the Qajar dynasty, had emerged under Agha Mohammad Khan Qajar, which would prove pivotal in the history of the short-lived kingdom.

The Nakhichevan Khanate (Persian: خانات نخجوان, romanized: Khānāt-e Nakhjavān) was a khanate under Iranian suzerainty, which controlled the city of Nakhichevan and its surroundings from 1747 to 1828. It was established by Heydar Qoli Khan after death of Nader Shah and was abolished following Treaty of Turkmenchay.

The territory of the khanate corresponded to most of the present-day Nakhchivan Autonomous Republic and Vayots Dzor Province of present-day Armenia.

The Afsharid dynasty (Persian: افشاریان) was an Iranian dynasty founded by Nader Shah (r. 1736–1747) of the Qirqlu clan of the Turkoman Afshar tribe, ruling over the Afsharid Empire.
