[5] His name was recorded in Bugut inscription in Sogdian: 𐼍𐼄𐼁 𐼇𐼍𐼎𐼁 𐼉𐼒𐼄𐼒𐼎,, romanized: Maġa Umna Khagan.
Turkish scholar Hayrettin İhsan Erkoç proposed Umna as proper reconstruction.
[6] According to Chinese sources he was enthroned after his father's death in 581, soon his cousin Talopien (Mukan Khagan's son) proposed his own claim, saying that Taspar willed the title to him.
Another cousin Shetu (Issik Khagan's son) supported Anluo, threatening to rebel if the throne is passed to Talopien.
In turn Shetu created him Dier Khagan (Chinese: 第二可汗; pinyin: Dìèr Kèhán) in Tuul River valley (now in Mongolia).
