Pagan kingdom

The Pagan Kingdom (Burmese: ပုဂံပြည် Băgam pyi [bəɡàɰ̃ pji]; lit. 'Bagan state'), also called Bagan Empire (ပုဂံဧကရာဇ်နိုင်ငံတော်) or the First Burmese Empire, was the first Burmese kingdom to unify the regions that would later constitute modern-day Myanmar. Its classical names are Arimaddanapura and Tampadīpa. Pagan's 250-year rule over the Irrawaddy valley and its periphery laid the foundation for the ascent of Burmese language and culture, the spread of Bamar ethnicity in Upper Myanmar, and the growth of Theravada Buddhism in Myanmar and in mainland Southeast Asia.
