Khwarazm in the context of "Karakalpakstan"

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.

Between 1219 and 1221, the Mongol forces under Genghis Khan invaded the lands of the Khwarazmian Empire in Central Asia. The campaign, which followed the annexation of the Qara Khitai Khanate, saw widespread devastation and atrocities. The invasion marked the completion of the Mongol conquest of Central Asia, and began the Mongol conquest of Persia.

Both belligerents, although large, had been formed recently: the Khwarazmian dynasty had expanded from their homeland to replace the Seljuk Empire in the late 1100s and early 1200s; nearly simultaneously, Genghis Khan had unified the Mongolic peoples and conquered the Western Xia dynasty. Although relations were initially cordial, Genghis was angered by a series of diplomatic provocations. When a senior Mongol diplomat was executed by Khwarazmshah Muhammed II, the Khan mobilized his forces, estimated to be between 90,000 and 200,000 men, and invaded. The Shah's forces were widely dispersed and probably outnumbered—realizing his disadvantage, he decided to garrison his cities individually to bog the Mongols down. However, through excellent organization and planning, the Mongols were able to isolate and conquer the Transoxianan cities of Bukhara, Samarkand, and Gurganj. Genghis and his youngest son Tolui then laid waste to Khorasan, destroying Herat, Nishapur, and Merv, three of the largest cities in the world. Meanwhile, Muhammed II was forced into flight by the forces of Mongol generals Subutai and Jebe; unable to reach any bastions of support, he died destitute on an island in the Caspian Sea. His son and heir Jalal-al Din managed to mobilize substantial forces, defeating a Mongol general at the Battle of Parwan, but these were crushed by Genghis at the Battle of the Indus a few months later.

Transoxiana or Transoxania (lit. 'Land beyond the Oxus', now called the Amu Darya) is the Latin name for the region and civilization located in lower Central Asia roughly corresponding to eastern Uzbekistan, western Tajikistan, parts of southern Kazakhstan, parts of Turkmenistan and southern Kyrgyzstan. The name was first coined by Alexander the Great in the 4th century BC when Alexander's troops conquered the region. The region may have had a similar Greek name in the days of Alexander the Great, but the earlier name is no longer known. Geographically, it is the region between the rivers Amu Darya to its south and the Syr Darya to its north.

The region of Transoxiana was one of the satrapies (provinces) of the Achaemenid Empire of Persia under the name Sogdia. It was defined within the classical world of Persia to distinguish it from Iran proper, especially its northeastern province of Khorasan, a term originating with the Sasanians, although early Arab historians and geographers tended to subsume the region within the loosely defined term "Khorasan" designating a much larger territory. The territories of Khwarazm, Sogdiana, Chaghaniyan, and Khuttal were located in the southern part of Transoxiana; Chach, Osrushana, and Farghana were located in the northern part.

Abu al-Qasim Mahmud ibn Sabuktigin (Persian: ابوالقاسم محمود بن سبکتگین, romanized: Abu al-Qāṣim Maḥmūd ibn Sabuktigīn; 2 October 971 – 30 April 1030), usually known as Mahmud of Ghazni or Mahmud Ghaznavi (محمود غزنوی), was Sultan of the Ghaznavid Empire, ruling from 998 to 1030. During his reign and in medieval sources, he is usually known by his honorific title Yamin al-Dawla (یمین‌ الدوله, lit. 'Right Hand of the State'). At the time of his death, his kingdom had been transformed into an extensive military empire, which extended from present-day northwestern Iran proper to the Punjab in the Indian subcontinent, Khwarazm in Transoxiana, and Makran.

Highly Persianized, Mahmud continued the bureaucratic, political, and cultural customs of his predecessors, the Samanids. He established the ground for a future Persianate state in Punjab, particularly centered on Lahore, a city he conquered. His capital of Ghazni evolved into a significant cultural, commercial, and intellectual centre in the Islamic world, almost rivalling the important city of Baghdad. The capital appealed to many prominent figures, such as al-Biruni and Ferdowsi.

The Anushtegin dynasty or Anushteginids (English: /ænuʃtəˈɡinid/, Persian: خاندان انوشتکین), also known as the Khwarazmian dynasty (Persian: خوارزمشاهیان) was a Sunni Muslim dynasty of Turkic mamluk origin from the Bekdili clan of the Oghuz Turks. The Anushteginid dynasty ruled the Khwarazmian Empire, consisting in large parts of present-day Central Asia, Afghanistan and Iran in the approximate period of 1077 to 1231, first as vassals of the Seljuks and the Qara Khitai (Western Liao), and later as independent rulers, up until the Mongol conquest of the Khwarazmian Empire in the 13th century.

The dynasty was founded by commander Anushtegin Gharchai, a former Turkic slave of the Seljuq sultans, who was appointed as governor of Khwarazm. His son, Qutb ad-Din Muhammad I, became the first hereditary Shah of Khwarazm. Anush Tigin may have belonged to either the Begdili tribe of the Oghuz Turks or to Chigil, Khalaj, Qipchaq, Qangly, or Uyghurs.

Abu Rayhan Muhammad ibn Ahmad al-Biruni, known as al-Biruni (c. 973 – c. 1050) was a Khwarazmian Iranian scholar and polymath during the Islamic Golden Age. He has been called variously "Father of Comparative Religion", "Father of modern geodesy", Founder of Indology and the first anthropologist.

Al-Biruni was well versed in physics, mathematics, astronomy, and natural sciences; he also distinguished himself as a historian, chronologist, and linguist. He studied almost all the sciences of his day and was rewarded abundantly for his tireless research in many fields of knowledge. Royalty and other powerful elements in society funded al-Biruni's research and sought him out with specific projects in mind. Influential in his own right, al-Biruni was himself influenced by the scholars of other nations, such as the Greeks, from whom he took inspiration when he turned to the study of philosophy. A gifted linguist, he was conversant in Khwarezmian, Persian, Arabic, and Sanskrit, and also knew Greek, Hebrew, and Syriac. He spent much of his life in Ghazni, then capital of the Ghaznavids, in modern-day central-eastern Afghanistan. In 1017, he travelled to the Indian subcontinent and wrote a treatise on Indian culture entitled Tārīkh al-Hind ("The History of India"), after exploring the Hindu faith practiced in India. He was, for his time, an admirably impartial writer on the customs and creeds of various nations, his scholarly objectivity earning him the title al-Ustadh ("The Master") in recognition of his remarkable description of early 11th-century India.

The Treaty of Akhal (Russian: Ахалский договор, Persian: پیمان آخال), also known as Akhal-Khorasan Boundary Convention, was an agreement signed between Qajar Iran and Imperial Russia on 21 September 1881 to mark Iran's official recognition of Khwarazm's (mostly the territory of present-day Turkmenistan) annexation by the Russian Empire.

The title of the treaty is derived from the name of the vast region north of Khorasan where the Turkmen tribe of Tekke lived – Akhal.
