Silla launched attacks on the Chinese in the following years defeating them in the north despite attacks from the Chinese in Silla. The Chinese were eventually driven out of the Korean peninsula by 676 AD resulting in a unification of the Three Kingdoms. This unification of Silla lasted for over 260 years until descendents of Koguryo and Peakje started rebellious movements. Silla was eventually replaced by the Koryo Dynasty.
