Former Qin

The Former Qin was a dynastic state in northern China during the Sixteen Kingdoms period, founded in 351 AD by the Fu clan of the Di peoples. It completed the unification of northern China in 376 AD under Fu Jiān, making it the only state of the Sixteen Kingdoms to do so. Its capital was Chang'an until 385 AD. A decisive defeat in 383 AD led to uprisings and the splitting of its territory. One remnant was overwhelmed by 386 AD, while the other struggled until its final disintegration in 394 AD due to invasions. All rulers proclaimed themselves "Emperor," except Fu Jiān, who used the title "Heavenly King."
