Ashina Tuwu (Chinese: 吐務) was an early Göktürks chief and ancestor of their khagans. Besides carrying title of Da Yehu (大葉護 Grand Yabgu), little else is known about him. He would be succeeded by his oldest son Bumin, who together with his younger brother Istämi founded the Gokturk Khaganate.
Bumin Qaghan (Old Turkic: 𐰉𐰆𐰢𐰣:𐰴𐰍𐰣, romanized: Bumïn qaɣan, died 552 AD) was the founder of the First Turkic Khaganate. His regnal title was Illig Qaghan (Chinese: 伊利可汗, romanized: Yīlì Kèhán, Wade–Giles: i-li k'o-han). He was the eldest son of Ashina Tuwu (吐務 / 吐务). He was the chieftain of the Turks under the sovereignty of the Rouran Khaganate. He is also mentioned as Tumen (土門, 吐門, commander of ten thousand) of the Rouran Khaganate.
