可萨汗国与拜占廷皇帝查士丁尼二世的关系在可萨—拜占廷关系史上很具有代表性。可萨可汗在查士丁尼二世被废黜后收留了他并与之联姻,但是在查士丁尼复辟后却支持反叛查士丁尼的起义军势力,最终推翻其统治。可萨与查士丁尼二世戏剧性的关系始终和可萨人在克里米亚的利益息息相关,正是国家的战略需要,决定了可萨对查士丁尼态度的转变。 The relationship between the Khanate and the Byzantine king Justinian II was representative in the history of the Kosa-Byzantine relations. But after the restoration of Justinian Gentile, Khathakhan rescues and marries Justinian II after he was deposed but supports the rebel forces rebelled against Justinian and eventually overthrows his rule. The dramatic relationship between Cosa and Justinian II has always been related to the interests of the Cesar in Crimea. It is precisely the strategic needs of the country that determine Cossa’s change of Justinian attitude.
