Gupta Empire

The Gupta Empire was an ancient Indian empire existing from the mid-to-late 3rd century CE to 543 CE. At its zenith, from approximately 319 to 467 CE, it covered much of the Indian subcontinent.[4] This period is considered as the Golden Age of India by the historians.[5][note 1] The ruling dynasty of the empire was founded by the king Sri Gupta; the most notable rulers of the dynasty were Chandragupta ISamudragupta, and Chandragupta II alias Vikramaditya. The 5th-century CE Sanskrit poet Kalidasa credits the Guptas with having conquered about twenty-one kingdoms, both in and outside India, including the kingdoms of Parasikas, the Hunas, the Kambojas, tribes located in the west and east Oxus valleys, the KinnarasKiratas, and others.[7][non-primary source needed]

Byzantine Empire under the Amorian dynasty

The Byzantine Empire was ruled by the Amorian or Phrygian dynasty from 820 to 867. The Amorian dynasty continued the policy of restored iconoclasm (the “Second Iconoclasm”) started by the previous non-dynastic emperor Leo V in 813, until its abolition by Empress Theodora with the help of Patriarch Methodios in 842.[1] The continued iconoclasm further worsened relations between the East and the West, which were already bad following the papal coronations of a rival line of “Roman Emperors” beginning with Charlemagne in 800. Relations worsened even further during the so-called Photian Schism, when Pope Nicholas I challenged Photios‘ elevation to the patriarchate.

During the Second Iconoclasm, the Empire began to see systems resembling feudalism being put in place, with large and local landholders becoming increasingly prominent, receiving lands in return for military service to the central government.[2] Similar systems had been in place in the Roman Empire ever since the reign of Severus Alexander during the third century, when Roman soldiers and their heirs were granted lands on the condition of service to the Emperor.[3]
