Early on, Ava fought wars of unification (1385–1424) but could never quite reassemble the lost empire. Having held off Ava, Hanthawaddy entered its golden age, and Arakan went on to become a power in its own right for the next 350 years. In contrast, constant warfare left Ava greatly weakened, and it slowly disintegrated from 1481 onward. In 1527, the Confederation of Shan States conquered Ava itself, and ruled Upper Myanmar until 1555.
Like the Pagan Empire, Ava, Hanthawaddy and the Shan states were all multi-ethnic polities. Despite the wars, cultural synchronisation continued. This period is considered a golden age for Burmese culture. Burmese literature "grew more confident, popular, and stylistically diverse", and the second generation of Burmese law codes as well as the earliest pan-Burma chronicles emerged.[59] Hanthawaddy monarchs introduced religious reforms that later spread to the rest of the country.[60] Many splendid temples of Mrauk U were built during this period.
