Title:
Myanmar

Context:
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. Hanthawaddy monarchs introduced religious reforms that later spread to the rest of the country. Many splendid temples of Mrauk U were built during this period.

Question:
Who increased the spread of religious reforms in Myanmar?

Hanthawaddy monarchs
