Mongol invasions of Georgia in the context of "Kingdom of Western Georgia"

The Kingdom of Georgia (Georgian: საქართველოს სამეფო, romanized: Sakartvelos samepo), also known as the Georgian Empire, was a medieval Eurasian monarchy that was founded in c. 1008 AD. It reached its Golden Age of political and economic strength during the reign of King David IV and Queen Tamar the Great from the 11th to 13th centuries. Georgia became one of the pre-eminent nations of the Christian East, and its pan-Caucasian empire and network of tributaries stretched from Eastern Europe to Anatolia and northern frontiers of Iran, while Georgia also maintained religious possessions abroad, such as the Monastery of the Cross in Jerusalem and the Monastery of Iviron in Greece. It is the principal historical precursor of present-day Georgia.

Kingdom of Georgia emerged in the early 11th century out of unification of various Georgian kingdoms, most notably the Kingdom of the Iberians and the Kingdom of Abkhazia. Lasting for nearly five centuries, the kingdom fell to the Mongol invasions in the 13th century, but managed to re-assert sovereignty by the 1340s. The following decades were marked by the Black Death, as well as numerous invasions under the leadership of Timur, who devastated the country's economy, population, and urban centers. The Kingdom's geopolitical situation further worsened after the conquest of the Byzantine Empire and the Empire of Trebizond by the Ottoman Turks. As a result of these processes, by the end of the 15th century Georgia turned into a fractured entity. This whole series of events also led to the final collapse of the kingdom into anarchy by 1466 and the mutual recognition of its constituent kingdoms of Kartli, Kakheti, and Imereti as independent states between 1490 and 1493—each led by a rival branch of the Bagrationi dynasty, and into five semi-independent principalities—Odishi, Guria, Abkhazia, Svaneti, and Samtskhe.

Georgians, or Kartvelians (/kɑːrtˈvɛliənz/; Georgian: ქართველები, romanized: kartvelebi, pronounced [kʰaɾtʰʷelebi]), are a nation and Caucasian ethnic group native to present-day Georgia and surrounding areas historically associated with the Georgian kingdoms. Significant Georgian diaspora communities are also present throughout Russia, Turkey, Greece, Iran, Ukraine, the United States, and the European Union.

Georgians arose from Colchian and Iberian civilizations of classical antiquity; Colchis was interconnected with the Hellenic world, whereas Iberia was influenced by the Achaemenid Empire until Alexander the Great conquered it. In the early 4th century, the Georgians became one of the first to embrace Christianity. Currently, the majority of Georgians are Orthodox Christians, with most following their national Georgian Orthodox Church; there are also small Georgian Catholic and Muslim communities as well as a significant number of irreligious Georgians. Located in the Caucasus, on the continental crossroads of Europe and Asia, the High Middle Ages saw Georgian people form a unified Kingdom of Georgia in 1008 AD, later inaugurating the Georgian Golden Age. This lasted until the kingdom was weakened and later disintegrated as the result of the 13th–15th-century invasions of the Mongols and Timur, the Black Death, the Fall of Constantinople, as well as internal divisions following the death of George V the Brilliant in 1346, the last of the great kings of Georgia.

The collapse of the Georgian realm (Georgian: ქართული სახელმწიფოს დაშლა, romanized: kartuli sakhelmts'ipos dashla) was a political and territorial fragmentation process that resulted in the dynastic triumvirate military conflict of the Bagrationi monarchs and war of succession in the united Kingdom of Georgia culminating during the second half of the 15th century.

The fragmentation of the unified realm started in the 13th century during the Mongol invasions that resulted in the establishment of de facto independent Kingdom of Western Georgia led by King David VI Narin and his successors, even though several reunifications would take place that would then bring back monarchy united in fold.

The nation of Georgia was first unified as a kingdom under the Bagrationi dynasty in 1008 AD, arising from several successor states of the ancient kingdoms of Colchis and Iberia. The Kingdom of Georgia flourished during the 11th and 12th centuries under King David IV of Georgia and Queen Tamar the Great. It fell to the Mongol invasion by 1243 but saw restoration of its former strength under the leadership of George V the Brilliant. Throughout the Middle Ages, Georgia was one of the preeminent powers of the Eastern Orthodox world.

Facing relentless invasions from much larger empires, by 1490 Georgia finally collapsed into several petty kingdoms and principalities, which throughout the Early Modern period feuded with one another and struggled to defend themselves against external threats, such as Ottoman and Persian encroachment. This prompted Georgian monarchs to increasingly seek an alliance with the Russian Empire, their Orthodox Christian neighbor to the north, culminating in the annexation of Georgia by the Russian Empire beginning in 1801.
