Jin begins to expand against Liao

1107

Jurchen raiders under Aguda's family began testing the Liao frontier in Manchuria, defeating larger Khitan forces by using their heavy cavalry in concentrated shock charges. The raids gave the Jurchen confidence they could eventually make themselves the masters of North China. Within a decade these border skirmishes would escalate into a full-scale war of conquest that shattered the Liao dynasty and redrew the political map of East Asia.
