Mashhad in the context of "Tobacco Protest"

Isfahan or Esfahan (Persian: اصفهان [esfæˈhɒːn] ) is a city in the Central District of Isfahan County, Isfahan province, Iran. It is the capital of the province, the county, and the district. It is located 440 kilometres (270 miles) south of Tehran. The city has a population of approximately 2,237,990, making it the fourth-most populous city in Iran, after Tehran, Mashhad and Karaj, and the second-largest metropolitan area.

Isfahan is located at the intersection of the two principal routes that traverse Iran, north–south and east–west. Isfahan flourished between the 9th and 18th centuries. Under the Safavid Empire, Isfahan became the capital of Iran, for the second time in its history, under Abbas the Great. It is known for its Persian–Muslim architecture, grand boulevards, covered bridges, palaces, tiled mosques, and minarets. Isfahan also has many historical buildings, monuments, paintings, and artifacts. The fame of Isfahan led to the Persian proverb Esfahān nesf-e-jahān ast ('Isfahan is half the world'). Naqsh-e Jahan Square in Isfahan is one of the largest city squares in the world, and a UNESCO World Heritage Site.

The Guarded Domains of Iran, alternatively the Sublime State of Iran and commonly called Qajar Iran, Qajar Persia or the Qajar Empire, was the Iranian state under the rule of the Qajar dynasty, which was of Turkic origin, specifically from the Qajar tribe, from 1789 to 1925. The Qajar family played a pivotal role in the Unification of Iran (1779–1796), deposing Lotf 'Ali Khan, the last Shah of the Zand dynasty, and re-asserted Iranian sovereignty over large parts of the Caucasus. In 1796, Agha Mohammad Khan Qajar seized Mashhad with ease, putting an end to the Afsharid dynasty. He was formally crowned as Shah after his punitive campaign against Iran's Georgian subjects.

In the Caucasus, the Qajar dynasty permanently lost much territory to the Russian Empire over the course of the 19th century, comprising modern-day eastern Georgia, Dagestan, Azerbaijan, and Armenia. Despite its territorial losses, Qajar Iran reinvented the Iranian notion of kingship and maintained relative political independence, but faced major challenges to its sovereignty, predominantly from the Russian and British empires. Foreign advisers became powerbrokers in the court and military. They eventually partitioned Qajar Iran in the 1907 Anglo-Russian Convention, carving out Russian and British influence zones and a neutral zone.

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.

Karaj (Persian: کرج; pronounced [kæˈɾædʒ] ) is a city in the Central District of Karaj County, Alborz province, Iran, serving as capital of the province, the county, and the district. Earliest evidence of inhabitation in Karaj can be dated to the Bronze Age at Tepe Khurvin. The city was developed under the rule of the Safavid and Qajar Empire and is home to historical buildings and memorials from those eras. This city has a unique climate due to access to natural resources such as many trees, rivers, and green plains. After Tehran, Karaj is the largest immigrant-friendly city in Iran, so it has been nicknamed "Little Iran."

Although the county hosts a population around 1.97 million, as recorded in the 2016 census, most of the 1,419 km (548 sq mi) county is rugged mountain. The urban area is the fourth-largest in Iran, after Tehran, Mashhad, and Isfahan. Eshtehard County and Fardis County were split off from Karaj County since the previous census.

The Iran–Turkmenistan border is the national border separating the countries of Iran and Turkmenistan. It is 1,148 km (713 miles) in length and runs from the Caspian Sea to the tripoint with Afghanistan. The Turkmen capital Ashgabat is only 15 miles north of this boundary, and Mashhad (Iran's second largest city) is 47 miles south of it.

Iran has one of the highest urban population growth rates in the world. From 1950 to 2002, the urban proportion of the population increased from 27% to 60%. The United Nations (UN) predicts that by 2030 80% of the population will live in urban areas. Most internal migrants have settled near the cities of Tehran, Isfahan, Karaj, Ahvaz, Mashhad and Qom. Tehran, with a population of 8.7 million in 2016, is the largest city in Iran and is the nation's capital. Tehran is home to around 11% of Iran's population. It is the hub of Iran's communication and transport networks.

Mashhad, with a population of 4.2 million in 2019, is the second-largest Iranian city and the centre of the province of Razavi Khorasan. Mashhad is one of the holiest Shi'a cities in the world as it is the site of the Imam Reza shrine. It is the centre of tourism in Iran. Between 15 and 20 million pilgrims go to Imam Reza's shrine every year.

The Arab conquest of Iran, which culminated in the fall of the Sasanian Empire to the nascent Rashidun Caliphate, brought about a monumental change in Iranian society by purging Zoroastrianism, which had been Iran’s official and majority religion since the time of the Achaemenid Empire. Since the Rashidun invasion, Islam (in any form) has consistently held the status of Iran's official religion except for a short period in the 13th century, when the Mongol invasions and conquests destroyed the Abbasid Caliphate and smaller Islamic realms before resulting in the establishment of the Ilkhanate. The process by which Iranian society became integrated into the Muslim world took place over many centuries, with nobility and city-dwellers being among the first to convert, in spite of notable periods of resistance, while the peasantry and the dehqans (land-owning magnates) took longer to do so. Around the 10th century, most Persians had become Muslims.

Between the 7th century and the 15th century, Sunni Islam was the dominant sect in Iran, and Iranian academics of this period contributed greatly to the Islamic Golden Age. In the 16th century, the newly enthroned Safavid dynasty initiated a massive campaign to install Shia Islam as Iran's official sect, aggressively proselytizing the faith and forcibly converting the Iranian populace. The Safavids' actions triggered tensions with the neighbouring Sunni-majority Ottoman Empire, in part due to the flight of non-Shia refugees from Iran. It is estimated that by the mid-17th century, Iran had become a Shia-majority nation. Over the following centuries, with the state-fostered rise of an Iran-based Shia clergy, a synthesis was formed between Iranian culture and Shia Islam that marked each indelibly with the tincture of the other. Later, under the Pahlavi dynasty, Islamic influence on Iranian society was rolled back in order to assert a new Iranian national identity—one that focused on pre-Islamic Iran by shedding more light on Zoroastrian tradition and other aspects of ancient Iranian society, particularly during the Achaemenid era. However, in 1979, the Islamic Revolution brought about yet another monumental change by ending the historic Iranian monarchy and replacing it with an Islamic republic.

The Hazaras (Persian: هزاره, romanized: Hazāra; Hazaragi: آزره, romanized: Āzrə) are an ethnic group and a principal component of Afghanistan's population. They are one of the largest ethnic groups in Afghanistan, primarily residing in the Hazaristan (Hazarajat) region in central Afghanistan. Hazaras also form significant minority communities in Pakistan, mainly in Quetta, and in Iran, primarily in Mashhad. They speak Dari and Hazaragi, dialects of Persian. Dari, also known as Dari Persian, is an official language of Afghanistan, alongside Pashto.

Between 1888 and 1893, more than half of the Hazara population was massacred under the Emirate of Afghanistan, and they have faced persecution at various times over the past decades. Widespread ethnic discrimination, religious persecution, organized attacks by terrorist groups, harassment, and arbitrary arrest for various reasons have affected Hazaras. There have been numerous cases of torture of Hazara women, land and home seizures, deliberate economic restrictions, economic marginalization of the Hazara region and appropriation of Hazara agricultural fields and pastures leading to their forced displacement from Afghanistan.
