The loyalty of the Varangians became a trope of Byzantine writers. Writing about her father Alexius's seizing of the Imperial throne in 1081, Anna Komnene notes that he was advised not to attack the Varangians who still guarded the Emperor Nikephoros for the Varangians "regard loyalty to the emperors and the protection of their persons as a family tradition, a kind of sacred trust". This allegiance, she noted, "they preserve inviolate, and will never brook the slighted hint of betrayal". Unlike the native Byzantine guards so mistrusted by Basil II, the Varangian guards' loyalties lay with the position of Emperor, not the man who sat on the throne. This was made clear in 969 when the guards failed to avenge the death by assassination of Emperor Nikephoros II. A servant had managed to call for the guards while the Emperor was being attacked, but when they arrived he was dead. They immediately knelt before John Tzimiskes, Nikephoros' murderer and hailed him as Emperor. "Alive they would have defended him to the last breath: dead there was no point in avenging him. They had a new master now."
