Tulan Qaghan (Chinese: 都蘭可汗/都兰可汗, Modern Chinese: (Pinyin): dōulán kěhàn, (Wade-Giles): tu-lan k'o-han, Middle Chinese: (Guangyun) [tu˥lɑn˩ kʰɑ˥ɣɑn˩˥], personal name: 阿史那雍虞閭/阿史那雍虞闾, āshǐnà yōngyúlǘ, a-shih-na yung-yü-lü) was the son of Ishbara and the seventh qaghan (Khaqan) of the Turkic Khaganate. He married his father's wife, Northern Zhou's Princess Qianjin, now known under the Sui Dynasty title Princess Dayi. Her new name was given to her by the Sui Emperor Wendi in order to create a marriage alliance with the Turks.
In 593 he collected enough power to stop paying taxes to Emperor Wendi. Secretly, she plotted with Dulan-qaghan's rival, Tuli to attack the Sui Empire when her husband refused. This plot was exposed by Chang sun-sheng, a spy of the Sui Empire.
