| The Byzantine Empire had been in contact with Sassanian Persia for four centuries,and the relationship between the two countries was complex and ever-changing.Before the founding of Sassanian Persia,Byzantium and the Persians engaged in alliances or wars.After the founding of the People’s Republic of China,both sides fought or reconciled,vying for hegemony in the eastern border area of Byzantium.In the 7th century AD,the Sassanian Persian Empire was lost in the long river of history.At the same time,a new force emerged on the Arabian Peninsula,breaking the pattern centered around the Byzantine Empire and Sassanian Persia.In the Arab expansion war,the Byzantine civilization and Sassanian Persia civilization also shaped it,ultimately promoting the establishment of the Arab Empire and the reconstruction of the new world pattern.This article mainly studies the diplomatic and military exchanges between the Byzantine Empire and Sassanian Persia from 518 to 651 and their impact.This includes diplomatic exchanges between the Byzantine Empire and Sassanian Persia,the decline of Sassanian Persia,and the establishment of a new order in the Two River Basin region after the rise of the Arabs.This article is divided into four parts: The first part mainly discusses the early diplomatic exchanges between Sassanopos and Byzantium from the 3rd to 5th century,including the impact of geographical environment and cultural composition on the exchanges between the two countries,as well as the process and historical influence of diplomatic exchanges between the Byzantine Empire and Sassanopos from the 3rd to 5th century.The second part explores the relationship between the Byzantine Empire and Sassanian Persia during the periods of Justin I,Justinian I,Justin II,and Tiberius I from 518 to 581 AD,and analyzes the characteristics of the Byzantine Empire’s interaction with Sassanian Persia between 518 and 581 AD.The 6th century AD was an important historical stage of diplomatic exchanges between the Byzantine Empire and Sassanian Persia.In 518,Justin I ascended the throne,ending the long-standing peace with the Sassanian Persian Empire.The subsequent failure of the "Torgu Incident" marked the freezing point of foreign relations between the two countries.During the reign of Justinian the Great,Sassanian Persia had strong power.In order to ensure peace in the east,Emperor Justinian adopted a strategy of "monetary diplomacy",using gold and silver wealth to seek peace with Sassanian Persia.However,this strategy had little effect.In561 AD,the two countries signed the "Fifty Year Peace Agreement".In572 AD,Justin II launched a fierce war against Sassanian Persia on the grounds of protecting Armenia,and peace between the two countries lasted only 11 years.The military failure of the Byzantine Empire led to the mental breakdown of Justin II,who was unable to handle court affairs,and the power of the empire was transferred to the hands of the deputy emperor Tiberius II.Tiberius II hoped to restore the previous peace with Sassanopos,but was rejected by Hormuz IV.Immediately,the Byzantine Empire dispatched Maurice to launch an expedition against Sassanopos.The third part explores the diplomatic exchanges between the Byzantine Empire and Sassanopos during the reigns of Maurice,Phocas,and Heraclius from 582 to 651,and explores the characteristics of the Byzantine Empire’s exchanges with Sassanopos from 582 to 651.Morris continued his military operations against Sassanopos after his accession to the throne.In 589 AD,internal turmoil broke out in Sassanne.The famous general Chu Bin conspired against the palace and forced the new emperor Hoslu II into exile in the Byzantine Empire,seeking help from Emperor Maurice.With the help of Maurice,Hosru II defeated Chubin in 591 AD and was restored.The lifting of the crisis of succession in Sassanne became an opportunity for the resumption of peace negotiations between the two countries.The diplomatic exchanges between the Byzantine Empire and the Sassanian Persian Empire entered a new era.The ’Foucus Rebellion’ once again shattered the hard-earned peace situation and continued until Heraclius succeeded.The fall of Jerusalem greatly dealt a blow to the Byzantine Empire’s prestige in the Christian world.As a result,Heraclius decided to launch a religious war and completely defeated the Sassanian Persian army in Nineveh in 627 AD.The fourth part discusses the impact of the rise and expansion of the Arabs on the Byzantine Empire and Sassanian Persia,as well as analyzes the changes in the political landscape of the Mediterranean after the rise of the Arabs. |
