Samarkand in the context of "Siege of Gurganj"

Uzbekistan, officially the Republic of Uzbekistan, is a doubly landlocked country located in Central Asia. It is surrounded by five countries: Kazakhstan to the north, Kyrgyzstan to the northeast, Tajikistan to the southeast, Afghanistan to the south, and Turkmenistan to the southwest, making it one of only two doubly landlocked countries on Earth, the other being Liechtenstein. The country has a population of more than 37.6 million, making it the most populous country in Central Asia. Uzbekistan is a member of the Organization of Turkic States. Uzbek, spoken by the Uzbek people, is the official language and spoken by the majority of its inhabitants, while Russian and Tajik are significant minority languages. Islam is the predominant religion, and most Uzbeks are Sunni Muslims.

The first recorded settlers in the land of what is contemporary Uzbekistan were Eastern Iranian nomads, known as Scythians, who founded kingdoms in Khwarazm, Sogdiana, and Bactria in the 8th–6th centuries BC, as well as Fergana and Margiana in the 3rd century BC – 6th century AD. The area was incorporated into the Achaemenid Empire and, after a period of Greco-Bactrian rule and later by the Sasanian Empire, until the Muslim conquest of Persia in the seventh century. The early Muslim conquests and the subsequent Samanid Empire converted most of the people into adherents of Islam. During this period, cities began to grow rich from the Silk Road, and became a center of the Islamic Golden Age. The local Khwarazmian dynasty was destroyed by the Mongol invasion in the 13th century, leading to a dominance by Mongol peoples. Timur in the 14th century established the Timurid Empire. Its capital was Samarkand, which became a center of science under the rule of Ulugh Beg, giving birth to the Timurid Renaissance. The territories of the Timurid dynasty were conquered by Kipchak Shaybanids in the 16th century. Conquests by Emperor Babur towards the east led to the foundation of the Mughal Empire in India. Most of Central Asia was gradually incorporated into the Russian Empire during the 19th century, with Tashkent becoming the political center of Russian Turkestan. In 1924, national delimitation created the Uzbek Soviet Socialist Republic as a republic of the Soviet Union. It declared independence as the Republic of Uzbekistan in 1991.

Sogdia (/ˈsɒɡdiə/) or Sogdiana was an ancient Iranian civilization between the Amu Darya and the Syr Darya rivers, and in present-day Uzbekistan, Turkmenistan, Tajikistan, Kazakhstan, and Kyrgyzstan. Sogdiana was also a province of the Achaemenid Empire, and listed on the Behistun Inscription of Darius the Great. Sogdiana was first conquered by Cyrus the Great, the founder of the Achaemenid Empire, and then was annexed by the Macedonian ruler Alexander the Great in 328 BC. It would continue to change hands under the Seleucid Empire, the Greco-Bactrian Kingdom, the Kushan Empire, the Sasanian Empire, the Hephthalite Empire, the Western Turkic Khaganate, and the Muslim conquest of Transoxiana.

The Sogdian city-states, although never politically united, were centered on the city of Samarkand. Sogdian, an Eastern Iranian language, is no longer spoken. However, a descendant of one of its dialects, Yaghnobi, is still spoken by the Yaghnobis of Tajikistan. It was widely spoken in Central Asia as a lingua franca and served as one of the First Turkic Khaganate's court languages for writing documents.

The Timurid Empire was a late medieval, culturally Persianate, Turco-Mongol empire that dominated Greater Iran in the early 15th century, comprising modern-day Iran, Iraq, Afghanistan, much of Central Asia, the South Caucasus, and parts of contemporary Pakistan, North India, and Turkey. The empire had a syncretic culture and combined Turkic, Mongolic, and Persian influences, with the last members of the dynasty being regarded as "ideal Perso-Islamic rulers".

The empire was founded by Timur (Tamerlane), a warlord of Turco-Mongol lineage, who established the empire in 1370 and ruled it until his death in 1405. He saw himself as the great restorer of the Mongol Empire of Genghis Khan, regarding himself as Genghis's heir, and closely associated with the Borjigin. Timur continued to have strong trade relations with Ming China and the Golden Horde, with Chinese diplomats like Ma Huan and Chen Cheng regularly traveling west to Samarkand to conduct trade. The empire led to the Timurid Renaissance, particularly during the reign of astronomer and mathematician Ulugh Begh.

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.

Babur (Persian: ببر, Persian: [bɑː.βuɾ]; 14 February 1483 – 26 December 1530; born Zahīr ud-Dīn Muhammad) was the founder of the Mughal Empire in the Indian subcontinent. He was a descendant of Timur and Genghis Khan through his father and mother respectively. He was also given the posthumous name of Firdaws Makani ('Dwelling in Paradise').

Born in Andijan in the Fergana Valley (now in Uzbekistan), Babur was the eldest son of Umar Shaikh Mirza II (1456–1494, Timurid governor of Fergana from 1469 to 1494) and a great-great-great-grandson of Timur (1336–1405). Babur ascended the throne of Fergana in its capital Akhsikath in 1494 at the age of twelve and faced rebellion. He conquered Samarkand two years later, only to lose Fergana soon after. In his attempt to reconquer Fergana, he lost control of Samarkand. In 1501, his attempt to recapture both the regions failed when the Uzbek prince Muhammad Shaybani defeated him and founded the Khanate of Bukhara.

Mīrzā Muhammad Tarāghāy bin Shāhrukh (Chagatay: میرزا محمد تراغای بن شاهرخ; Persian: میرزا محمد طارق بن شاهرخ), better known as Ulugh Beg (Persian: الغ‌بیک; 22 March 1394 – 27 October 1449), was a Timurid sultan, as well as an astronomer and mathematician.

Ulugh Beg was notable for his work in astronomy-related mathematics, such as trigonometry and spherical geometry, as well as his general interests in the arts and intellectual activities. It is thought that he spoke five languages: Arabic, Persian, Chaghatai Turkic, Mongolian, and a small amount of Chinese. During his rule (first as a governor, then outright) the Timurid Empire achieved the cultural peak of the Timurid Renaissance through his attention and patronage. Samarkand was captured and given to Ulugh Beg by his father Shah Rukh.

The siege of Samarkand took place in March 1220 after Genghis Khan, founder of the Mongol Empire, had launched a multi-pronged invasion of the Khwarazmian Empire, ruled by Shah Muhammad II. The Mongols had laid siege to the border town of Otrar, but finding its defences obdurate, a large force commanded by Genghis and his youngest son Tolui detached from the vanguard and set off southwards, towards Transoxiana.

Samarkand was the Shah's capital and the pivot of his defence — the city's garrison was large and its battlements were one of the strongest in the empire. Genghis, however, managed to isolate it by capturing and destroying Bukhara in a surprise manoeuvre, and then laying waste to the nearby Transoxianan towns. After repelling relief forces, the Mongol army, now reinforced after the capture of Otrar, ambushed and massacred a sortie by the town's defenders. The citizens of the city soon surrendered at the instigation of the Muslim clergy; most were however enslaved or conscripted in traditional Mongol fashion.
