Nomad in the context of "Tundra"

Human history or world history is the record of humankind from prehistory to the present. Modern humans evolved in Africa around 300,000 years ago and initially lived as hunter-gatherers. They migrated out of Africa during the Last Ice Age and had spread to every continent except Antarctica by the end of the Ice Age 12,000 years ago. Soon afterward, the Neolithic Revolution in West Asia brought the first systematic husbandry of plants and animals, and saw many humans transition from nomadic lives to sedentary existences as farmers in permanent settlements. The growing complexity of human societies necessitated systems of accounting and writing.

These developments paved the way for the emergence of early civilizations in Mesopotamia, Egypt, Peru, the Indus Valley, and China, marking the beginning of the ancient period in the 4th millenium BCE. These civilizations enabled the establishment of regional empires and provided fertile ground for the advent of transformative philosophical and religious ideas. Hinduism originated during the late Bronze Age and was followed by the many seminal belief systems of the Axial Age: Buddhism, Confucianism, Greek philosophy, Jainism, Judaism, Taoism, and Zoroastrianism. Christianity began later as an offshoot of Judaism. The subsequent post-classical period, from about 500 to 1500 CE, witnessed the rise of Islam and China's flourishing under the Tang and Song dynasties while civilization expanded to new parts of the world and trade between societies increased. The political landscape was shaped by the rise and fall of major empires, such as the Byzantine Empire, the Islamic caliphates, and the Mongol Empire. This period's invention of gunpowder and the printing press greatly affected later history.

The Bulgars (also Bulghars, Bulgari, Bolgars, Bolghars, Bolgari, Proto-Bulgarians) were Turkic semi-nomadic warrior tribes that flourished in the Pontic–Caspian steppe and the Volga region between the 5th and 7th centuries. They became known as nomadic equestrians in the Volga-Ural region, but some researchers trace Bulgar ethnic roots to Central Asia.

During their westward migration across the Eurasian Steppe, the Bulgar tribes absorbed other tribal groups and cultural influences in a process of ethnogenesis, including Iranic, Uralic, and Hunnic tribes. The Bulgars spoke a Turkic language, the Bulgar language of the Oghuric branch. They preserved the military titles, organization, and customs of Eurasian steppes as well as pagan shamanism and belief in the sky deity Tangra.

A hunter-gatherer or forager is a human living in a community, or according to an ancestrally derived lifestyle, in which most or all food is obtained by foraging, that is, by gathering food from local naturally occurring sources or by hunting game. This is a common practice among most vertebrates that are omnivores. Hunter-gatherer groups, usually a few dozen people, were and are nomadic or semi-nomadic. Hunter-gatherer societies are contrasted with more sedentary agricultural societies, which rely mainly on cultivating crops and raising domesticated animals for food production.

Hunting and gathering emerged with Homo erectus about 1.8 million years ago and was humanity's original and most enduring successful competitive adaptation in the natural world, occupying at least 90 percent of human (pre)history. Following the invention of agriculture, hunter-gatherers who did not change were displaced or conquered by farming or pastoralist groups in most parts of the world. In Western Eurasia, farming and metallurgical societies gradually replaced hunter-gatherers, but dense forests remained their last refuge until Bronze and Iron Age societies fully overcame them.

The Mongol Empire was the largest contiguous empire in history. Originating in present-day Mongolia in East Asia, the empire at its height stretched from the Sea of Japan to Eastern Europe, extending northward into Siberia and east and southward into the Indian subcontinent, mounting invasions of Southeast Asia, and conquering the Iranian plateau; and reaching westward as far as the Levant and the Carpathian Mountains.

The empire emerged from the unification of several nomadic tribes in the Mongol heartland under the leadership of Temüjin, known by the title of Genghis Khan (c. 1162–1227), whom a council proclaimed as the ruler of all Mongols in 1206. The empire grew rapidly under his rule and that of his descendants, who sent out invading armies in every direction. The vast transcontinental empire connected the East with the West, and the Pacific to the Mediterranean, in an enforced Pax Mongolica, allowing the exchange of trade, technologies, commodities, and ideologies across Eurasia.

A yurt (from the Turkic languages) or ger (Mongolian) is a portable, round tent covered and insulated with skins or felt and traditionally used as a dwelling by several distinct nomadic groups in the steppes and mountains of Inner Asia. The structure consists of a flexible angled assembly or latticework of wood or bamboo for walls, a door frame, ribs (poles, rafters), and a wheel (crown, compression ring) possibly steam-bent as a roof. The roof structure is sometimes self-supporting, but large yurts may have interior posts or columns supporting the crown. The top of the wall of self-supporting yurts is prevented from spreading by means of a tension band which opposes the force of the roof ribs. Yurts take between 30 minutes and three hours to set up or take down, and are generally used by between five and 15 people. Nomadic farming with yurts as housing has been the primary way of life in Central Asia, particularly Mongolia, for thousands of years.

Modern yurts may be permanently built on a wooden or concrete platform; they may use modern materials such as metal framing, plastics, plexiglass dome, or radiant insulation.

Eurasian nomads form groups of nomadic peoples who have lived in various areas of the Eurasian Steppe. History largely knows them via frontier historical sources from Europe and Asia.

The steppe nomads had no permanent abode, but travelled from place to place to find fresh pasture for their livestock. The generic designation encompasses the varied ethnic groups who have at times inhabited steppe regions of present-day Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan, Uyghuristan, Mongolia, Russia, and Ukraine.

The Scythians (/ˈsɪθiən/ or /ˈsɪðiən/) or Scyths (/ˈsɪθs/), also known as the Pontic Scythians, were an ancient Eastern Iranic equestrian nomadic people who migrated during the 9th to 8th centuries BC from Central Asia to the Pontic Steppe in modern-day Ukraine and Southern Russia, where they remained until the 3rd century BC.

Skilled in mounted warfare, the Scythians displaced the Agathyrsi and the Cimmerians as the dominant power on the western Eurasian Steppe in the 8th century BC. In the 7th century BC, the Scythians crossed the Caucasus Mountains and often raided West Asia along with the Cimmerians.

The Georgian Golden Age (Georgian: საქართველოს ოქროს ხანა, romanized: sakartvelos okros khana) describes a historical period in the High Middle Ages, spanning from roughly the late 11th to 13th centuries, during which the Kingdom of Georgia reached the peak of its power and development. In addition to military expansion, this period saw the flourishing of medieval Georgian architecture, painting and poetry, which was frequently expressed in the development of ecclesiastic art, as well as the creation of the first major works of secular literature.

Lasting more than two centuries, the Golden Age came to a gradual end due to persistent invasions of nomads, such as Mongols, as well as the spread of Black Death by these same nomadic groups. Georgia further weakened after the Fall of Constantinople, which effectively marked the end of the Eastern Roman Empire, Georgia's traditional ally. As a result of these processes, by the 15th century Georgia fractured and turned into an isolated enclave, largely cut off from Christian Europe and surrounded by hostile Islamic Turco-Iranic neighbors. For Georgia, the Golden Age forms an important part of its status as a once-powerful and ancient nation that maintained relations with Greece and Rome.
