Mongol Empire in the context of "Golden Horde"

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.

Several empires in human history have been contenders for the largest of all time, depending on definition and mode of measurement. Possible ways of measuring size include area, population, economy, and power. Of these, area is the most commonly used because it has a relatively precise definition and can be feasibly measured with some degree of accuracy; nevertheless, even area is limited in this regard because of the difficulty in defining the boundaries of empires due to things like the indirect nature of imperial control and sparsely inhabited or even uninhabited areas that may nominally have been controlled by an empire but not meaningfully ruled by it.

Estonian political scientist Rein Taagepera, who published a series of academic articles about the territorial extents of historical empires between 1978 and 1997, and a book in 2024, defined an empire in this context as "any relatively large sovereign political entity whose components are not sovereign" and its size as the area over which the empire has some undisputed military and taxation prerogatives. The list is not exhaustive as there is a lack of available data for several empires; for this reason and because of the inherent uncertainty in the estimates, no rankings are given.

Georgia is a country in the Caucasus region on the coast of the Black Sea. It is located at the intersection of Eastern Europe and West Asia, and is today generally regarded as part of Europe. It is bordered to the north and northeast by Russia, to the south by Turkey and Armenia, and to the southeast by Azerbaijan. Georgia covers an area of 69,700 square kilometres (26,900 sq mi). It has a population of 3.9 million, of which over a third live in the capital and largest city, Tbilisi. Ethnic Georgians, who are native to the region, constitute a majority of the country's population and are its titular nation.

Georgia has been inhabited since prehistory, hosting the world's earliest known sites of winemaking, gold mining, and textiles. The classical era saw the emergence of several kingdoms, such as Colchis and Iberia, that formed the nucleus of the modern Georgian state. In the early fourth century, Georgians officially adopted Christianity, which contributed to their unification under the Kingdom of Georgia. Georgia reached its Golden Age during the High Middle Ages under the reigns of King David IV and Queen Tamar. Beginning in the 15th century, the kingdom declined and disintegrated due to internal discord and pressure from various regional powers, including the Mongols, the Ottoman Empire, and Persia, before being gradually annexed into the Russian Empire starting in 1801.

The Middle East, or the Near East, was one of the cradles of civilization: after the Neolithic Revolution and the adoption of agriculture, many of the world's oldest cultures and civilizations were created there. Since ancient times, the Middle East has had several lingua franca: Akkadian, Hebrew, Aramaic, Greek, and Arabic. The Sumerians, around the 5th millennium BC, were among the first to develop a civilization. By 3150 BC, Egyptian civilization unified under its first pharaoh. Mesopotamia hosted powerful empires, notably Assyria which lasted for 1,500 years. For centuries after the 7th century BC, the region was dominated by Persian powers like the Achaemenid Empire.

In the 1st century BC, the Roman Republic conquered most of the region, and its successor, the Roman Empire, that ruled from the 6th to 15th centuries AD referred to as the Byzantine Empire, grew significantly more. Roman pagan religions were replaced by Christianity in the 4th century AD. From the 3rd to 7th centuries, Rome ruled alongside the Sasanian Empire. From the 7th century, Islam spread rapidly, expanding Arab identity in the region. The Seljuk dynasty displaced Arab dominance in the 11th century, followed by the Mongol Empire in the 13th century.

In world history, post-classical history refers to the period from about 500 CE to about 1450 or 1500 CE, roughly corresponding to the European Middle Ages following the decline of the western Roman Empire. The post-classical period is characterized by the expansion of certain civilizations geographically, by ongoing wars fought over land, resources and religion, and by the development of trade networks between often-distant civilizations. This period is also called—with various implications and emphases—the medieval era, the post-antiquity era, the post-ancient era, or the pre-modern era.

In Asia and the Middle East during this time, the spread of Islam helped produce a series of caliphates which fostered the Islamic Golden Age, leading to advances in science and greater trade between those in the Asian, African, and European continents. East Asia experienced the entrenchment of the power of a unitary and Imperial China, the dynastic governance and culture of which influenced Japan, Korea and Vietnam. Religions such as Buddhism and neo-Confucianism spread in the region, while Christianity became entrenched in Europe and increasingly elsewhere. Gunpowder was developed in China during the post-classical era. The Mongol Empire conquered and controlled much of Europe and Asia, permitting more trade and cultural and intellectual exchange between the two regions.

The Song dynasty (/sʊŋ/ SUUNG) was a unifying imperial dynasty of China that ruled from 960 to 1279. The dynasty was founded by Emperor Taizu of Song, who usurped the throne of the Later Zhou dynasty and went on to conquer the rest of the Ten Kingdoms, ending the Five Dynasties and Ten Kingdoms period. The Song often came into conflict with the contemporaneous Liao, Western Xia and Jin dynasties in northern China. After retreating to southern China following attacks by the Jin dynasty, the Song was eventually conquered by the Mongol-led Yuan dynasty.

The dynasty's history is divided into two periods: during the Northern Song (北宋; 960–1127), the capital was in the northern city of Bianjing (now Kaifeng) and the dynasty controlled most of what is now East China. The Southern Song (南宋; 1127–1279) comprise the period following the loss of control over the northern half of Song territory to the Jurchen-led Jin dynasty in the Jin–Song wars. At that time, the Song court retreated south of the Yangtze and established its capital at Lin'an (now Hangzhou). Although the Song dynasty had lost control of the traditional Chinese heartlands around the Yellow River, the Southern Song Empire contained a large population and productive agricultural land, sustaining a robust economy. In 1234, the Jin dynasty was conquered by the Mongols, who took control of northern China, maintaining uneasy relations with the Southern Song. Möngke Khan, the fourth Great Khan of the Mongol Empire, died in 1259 while besieging the mountain castle Diaoyucheng in Chongqing. His younger brother Kublai Khan was proclaimed the new Great Khan and in 1271 founded the Yuan dynasty. After two decades of sporadic warfare, Kublai Khan's armies conquered the Song dynasty in 1279 after defeating the Southern Song in the Battle of Yamen, and reunited China under the Yuan dynasty.

The Jin dynasty (/dʒɪn/, Chinese: 金朝; pinyin: Jīn cháo), officially the Great Jin (大金; Dà Jīn), was a Jurchen-led imperial dynasty of China and empire ruled by the Wanyan clan that existed between 1115 and 1234. It is also often called the Jurchen dynasty or the Jurchen Jin after the ruling Jurchen people. At its peak, the empire extended from Outer Manchuria in the north to the Qinling–Huaihe Line in the south.

The Jin dynasty emerged from Wanyan Aguda's rebellion against the Liao dynasty (916–1125), which held sway over northern China until being driven by the nascent Jin to the Western Regions, where they would become known in Chinese historiography as the Western Liao. After conquering the Liao territory, the Jin launched a century-long campaign against the Song dynasty (960–1279) based in southern China, whose rulers were ethnically Han Chinese. Over the course of the Jin's rule, their emperors adapted to Han customs and even fortified the Great Wall against the ascendant Mongol Empire. The Jin also oversaw a number of internal cultural advances, such as the revival of Confucianism.
