Later Qin
In 403, in light of pressure from Tufa Rutan and Juqu Mengxun, Lü Long decided to end his state, surrendering Guzang to Later Qin. Tufa Rutan, apprehensive of Later Qin's power, withdrew his troops to allow Later Qin forces through to Guzang to receive Lü Long and the city. In 404, he further ended his nominal independence (but not actual independence) by ending the use of his own era name and instead using Later Qin's to show allegiance to Later Qin. He stopped using his own princely title, and used only the Later Qin-created title of Duke of Guangwu. He also made a request to Yao Xing that he be allowed to have Guzang, but Yao Xing refused.
