Pagan reached the height of political and administrative development during the reigns of Narapatisithu (Sithu II; r. 1174–1211) and Htilominlo (r. 1211–1235). The Sulamani Temple, Gawdawpalin Temple, Mahabodhi Temple, and Htilominlo Temple were built during their reigns. The kingdom's borders expanded to its greatest extent. Military organisation and success reached their zenith. Monumental architecture achieved a qualitative and quantitative standard that subsequent dynasties tried to emulate but never succeeded in doing. The court finally developed a complex organisation that became the model for later dynasties. the agricultural economy reached its potential in Upper Burma. The Buddhist clergy, the "sangha", enjoyed one of its most wealthy periods. Civil and criminal laws were codified in the vernacular, Burmese, to become the basic jurisprudence for subsequent ages.
