The Kingdom of Georgia lasted for centuries.
The Kingdom of Georgia , also known as the Georgian Empire , was a medieval monarchy which emerged in circa 1008 AD . Lasting for several centuries , the kingdom fell to the Mongol invasions in the 13th century , but managed to re-assert sovereignty by the 1340s . As a result of these processes , by the end of the 15th century Georgia turned into an isolated , fractured Christian enclave , surrounded by hostile Turco-Iranic neighbors .
