Cultural integration continued. For the first time in history, the Burmese language and culture came to predominate the entire Irrawaddy valley, with the Mon language and ethnicity completely eclipsed by 1830. The nearer Shan principalities adopted more lowland norms. The evolution and growth of Burmese literature and theater continued, aided by an extremely high adult male literacy rate for the era (half of all males and 5% of females).[30] Monastic and lay elites around the Konbaung kings, particularly from Bodawpaya's reign, also launched a major reformation of Burmese intellectual life and monastic organization and practice known as the Sudhamma Reformation. It led to amongst other things Burma's first proper state histories.
