The Perioecian Wars is the name given to a series of minor conflicts and skirmishes in the 19th century concerning the border between Albic Vinland and the Fusangian states of Zhengguo and Alasijia. The disputes arose during the aftermath of the First World War as settlers began to arrive in the region from both directions, claiming the land for their respective home countries, and were ended by the 1874 Treaty of Tianshi that defined the present-day border.
