The Kingdom of Ava was the dominant kingdom that ruled upper Burma (Myanmar) from 1365 to 1555. Founded in 1365, the kingdom was the successor state to the petty kingdoms of Myinsaing, Pinya and Sagaing that had ruled central Burma since the collapse of the Pagan Empire in the late 13th century.

Burmese is a Sino-Tibetan language spoken in Myanmar, where it is the official language, lingua franca, and the native language of the Bamar, the country's principal ethnic group. Burmese is also spoken by the indigenous tribes in Chittagong Hill Tracts in Bangladesh, and in Tripura state in India. The Constitution of Myanmar officially refers to it as the Myanmar language in English, though most English speakers continue to refer to the language as Burmese, after Burma—a name with co-official status that had historically been predominantly used for the country. Burmese is the most widely-spoken language in the country, where it serves as the lingua franca. In 2007, it was spoken as a first language by 33 million. Burmese is spoken as a second language by another 10 million people, including ethnic minorities in Myanmar like the Mon and also by those in neighboring countries. In 2022, the Burmese-speaking population was 38.8 million.
