Nomadic empire in the context of "Old Great Bulgaria"

Mongolia is a landlocked country in East Asia. Bordered by Russia to the north and China to the south and southeast, it covers an area of 1,564,116 square kilometres (603,909 square miles), making it the 18th-largest country in the world and the second largest landlocked country after Kazakhstan, as well as the largest landlocked country that does not border an inland sea. With a population of 3.5 million, it is the world's most sparsely populated sovereign state. The country constitutes a significant portion of the Mongolian Plateau, and its natural environment is characterized by grassy steppe, mountains to the north and west, and the Gobi Desert to the south. Ulaanbaatar, the capital and largest city, is home to roughly half of the country's population.

The territory of modern-day Mongolia has been ruled by various nomadic empires, including the Xiongnu, the Xianbei, the Rouran, the First Turkic Khaganate, the Second Turkic Khaganate, the Uyghur Khaganate and others. In 1206, Genghis Khan founded the Mongol Empire, which became the largest contiguous land empire in history. His grandson Kublai Khan conquered China proper and established the Yuan dynasty. After the collapse of the Yuan, the Mongols retreated to Mongolia and resumed their earlier pattern of factional conflict, except during the era of Dayan Khan and Tumen Zasagt Khan.

Various nomadic empires, including the Xiongnu (3rd century BC–1st century AD), the Xianbei state (c. AD 93–234), the Rouran Khaganate (330–555), the First (552–603) and Second Turkic Khaganates (682–744) and others, ruled the area of present-day Mongolia. The Khitan people, who used a para-Mongolic language, founded an empire known as the Liao dynasty (916–1125), and ruled Mongolia and portions of North China, northern Korea, and the present-day Russian Far East.

In 1206, Genghis Khan was able to unite the Mongol tribes, forging them into a fighting force which went on to establish the largest contiguous empire in world history, the Mongol Empire (1206–1368). After the fragmentation of the Mongol Empire, Mongolia came to be ruled by the Yuan dynasty (1271–1368) based in Khanbaliq (modern Beijing) and administered as part of the Lingbei Province. Buddhism in Mongolia began with the Yuan emperors' conversion to and dissemination of Tibetan Buddhism.

The Eurasian Steppe, also called the Great Steppe or The Steppes, is the vast steppe ecoregion of Eurasia in the temperate grasslands, savannas and shrublands biome. It stretches through Manchuria, Mongolia, Xinjiang, Kazakhstan, Siberia, European Russia, Ukraine, Moldova, Romania, Bulgaria, Hungary and Slovakia.

Since the Paleolithic age, the Steppe Route has been the main overland route between Eastern Europe, North Asia, Central Asia and East Asia economically, politically, and culturally. The Steppe route is a predecessor not only of the Silk Road, which developed during antiquity and the Middle Ages, but also of the Eurasian Land Bridge in the modern era. It has been home to nomadic empires and many large tribal confederations and ancient states throughout history, such as the Xiongnu, Scythia, Cimmeria, Sarmatia, Hunnic Empire, Sogdia, Xianbei, Mongol Empire, Magyar tribes, and Göktürk Khaganate.

The Khazars (/ˈxɑːzɑːrz/) were a semi-nomadic Turkic people who established a major commercial empire in the late 6th century CE spanning modern southeastern Russia, southern Ukraine, and western Kazakhstan. It was the most powerful polity to emerge from the break-up of the Western Turkic Khaganate. Astride a major artery of commerce between Eastern Europe and Southwestern Asia, Khazaria became one of the foremost trading empires of the early medieval world, commanding the western marches of the Silk Road and playing a key commercial role as a crossroad between China, the Middle East, and Kievan Rus'. For some three centuries (c. 650–965), the Khazars dominated the vast area extending from the Volga-Don steppes to the eastern Crimea and the northern Caucasus.

Although they were likely a confederation of different Turkic-speaking peoples, the precise origins and nature of the Khazars are uncertain, since there is no surviving record in the Khazar language and the state was multilingual and polyethnic. Their native religion is thought to have been Tengrism, like that of the North Caucasian Huns and other Turkic peoples, although their multiethnic population seems to have included pagans, Jews, Christians, and Muslims. Although there is evidence that the ruling elite of the Khazars had converted to Rabbinic Judaism in the 8th century, the scope of the conversion to Judaism within the khanate remains uncertain.

A border barrier, border fence or border wall is a separation barrier that runs along or near an international border. Such barriers are typically constructed for border control purposes such as curbing illegal immigration, human trafficking, and smuggling. Some such barriers are constructed for defence or security reasons. In cases of a disputed or unclear border, erecting a barrier can serve as a de facto unilateral consolidation of a territorial claim that can supersede formal delimitation. A border barrier does not usually indicate the location of the actual border, and is usually constructed unilaterally by a country, without the agreement or cooperation of the other country.

Examples of border walls include the ancient Great Wall of China, a series of walls separating China from nomadic empires to the north. The construction of border barriers increased in the early 2000s; half of all the border barriers built since World War II, which ended in 1945, were built after 2000.

A khanate (/ˈxɑːneɪt, -ət/ KHAHN-ayt, -⁠ət) or khaganate was a polity ruled by a khan, khagan, khatun, or khanum. Khanates were typically nomadic Mongolic and Turkic societies located on the Eurasian Steppe, and politically equivalent in status to kinship-based chiefdoms and feudal monarchies. Khanates and khaganates were organised tribally, where leaders gained power on the support and loyalty of their warrior subjects, gaining tribute from subordinates as realm funding. In comparison to a khanate, a khaganate, the realm of a khagan, was a large nomadic state maintaining subjugation over numerous smaller khanates. The title of khagan, translating as "Khan of the Khans", roughly corresponds in status to that of an emperor.

The Dzungar genocide (Chinese: 準噶爾滅族; pinyin: Zhǔngáěr mièzú) was the mass extermination of the Dzungar people (Oirat Mongols) by the Qing dynasty. The Qianlong Emperor ordered the genocide after the rebellion in 1755 by Dzungar leader Amursana against Qing rule, after the dynasty first conquered the Dzungar Khanate with Amursana's support. The genocide was perpetrated by Manchu and Han generals of the Qing army, supported by Turkic oasis dwellers (now known as Uyghurs) who rebelled against Dzungar rule.

The Dzungar Khanate was a confederation of several Tibetan Buddhist Oirat Mongol tribes that emerged in the early 17th century, and the last great nomadic empire in Asia. Some scholars estimate that about 80% of the Dzungar population, or around 500,000 to 800,000 people, were killed by a combination of warfare and disease during or after the Qing conquest in 1755–1757. After wiping out the native population of Dzungaria, the Qing government then resettled Han, Hui, Uyghur, and Sibe people on state farms in Dzungaria, along with Manchu Bannermen to repopulate the area.
