President Feng Guozhang, with his term expiring, was then succeeded by Xu Shichang, who wanted to negotiate with the southern provinces. In February 1919 delegates from the northern and southern provinces convened in Shanghai to discuss postwar situations.

The Constitutional Protection War essentially left China divided along the north–south border.
