Jurchen people
Unlike the Jurchen people, who spoke the Jin Jurchen language that was adopted from phonetic Kitan language established in the Jin dynasty, the Jianzhou Jurchens commonly used three different language: Jurchen, Mongolian and Chinese. According to the Qing imperial history, the Jianzhou leader Nurgaci sought to devise a suitable system that integrated the phonetic Mongolian and Jurchen language. This resulted in the creation of the Manchu language, which would later be deemed one of the greatest inventions that sparked the unification of Manchuria. However, for some time the script was not well received and the Jianzhou continued to use Mongolian as their lingua franca.
