ビルマ語
The Burmese language and culture gradually became dominant in the upper Irrawaddy valley, eclipsing the Pyu and Pali norms by the late 12th century. By then, the Bamar leadership of the kingdom was unquestioned. The Pyu had largely assumed the Bamar ethnicity in Upper Burma. The Burmese language, once an alien tongue, was now the lingua franca of the kingdom.
