The Pa-Oh, also known as Taungthu and Black Karen, form an ethnic group in Burma, comprising approximately 600,000. The Pa-Oh form the second largest ethnic group in Shan State, and are classified as part of the "Shan National Race" by the government, although they are believed to be of Tibeto-Burman stock, and are ethnolinguistically related to the Karen. They populate Shan State, Kayin State, and Kayah State. The Full Moon of Tabaung is celebrated as the Pa-O National Day, traditionally set on the day of King Suriyachanda_s birth. The Pa-Oh settled in the Thaton region of present-day Myanmar about 1000 B.C. Historically, the Pa-Oh wore colorful clothing, until King Anawratha defeated the Mon King Makuta, who had established his reign in Thaton. The Pa-Oh were enslaved, and forced to wear indigo-dyed clothing, to signify their status. However, there are regional variations of clothing among the Pa-Oh.
