The Thathanabaing of Burma served as the head of the BuddhistSangha in pre-colonial Burma, until the position was abolished in 1938 by the British authorities in colonial Burma. The Thathanapaing was responsible for managing the monastic hierarchy and education at monasteries. The Thathanabaing resided in a royal monastery near the kingdom's capital. However, appointees were usually commoners born in the villages, with no blood relationship with the royal house. Their appointments were made on the basis of their mastery of Buddhist knowledge and literature.
Etymology
Thathanabaing, literally 'Keeper of the Sāsana', is the native Burmese rendition of Sangharaja, or formally Mahasangharaja, which is typically rendered into English as 'Primate', 'Archbishop' or 'Supreme Patriarch.' The term "Sangharaja" was popularly used from the 1300s to 1400s, but lost currency in subsequent centuries. By the Konbaung dynasty, Thathanabaing and Thathanapyu were frequently used.
The office, in its last incarnation, was established by King Bodawpaya in 1784, after the constitution of the Sudhamma Council, a council of four elder monks, of which the Thathanabaing was its head. Subsequent monarchs expanded the Council, which varied from 8 to 12 members called sadaw. Council members were appointed by the king and styled Dazeitya Sayadaw. The Thathanabaing was appointed by the king and granted supreme authority with regard to religious doctrine and ecclesiastical administration. The Thathanapaing was responsible for the kingdom's religious affairs, including appointment of monastery abbots, monk orders according to the Vinaya, management of breaches of discipline, preparation of an annual report of the order, and administration of Pali examinations. The Thathanabaing was charged with managing the functions of two government officials, the Mahadan Wun, who oversaw the king's charitable functions, ensured monk compliance with the Vinaya, and submitted registers of all active novices and monks, and the Wutmye Wun, who managed the wuttukan-designated religious properties, including donated land and pagodas. The Burmese kingdom was divided into ecclesiastical jurisdictions, each of which was overseen by a gaing-gyok. Underneath each gaing-gyok was a number of gaing-ok, who were in turn assisted by a number of gaing-dauk. Ecclesiastical disputes were settled by the gaing-gyok and decisions for appeal were made by the Sudhamma Council.
Colonial rule
In 1895, soon after the abdication of the country's last king, Thibaw Min, the Taungdaw Sayadaw, then the Thathanapaing of Burma, died. A subsequent election elected the Pakhan Sayadaw as Thathanabaing-elect, although the British refused to acknowledge or recognize his title. In 1903, the lieutenant-governor of British Burma, Hugh Shakespear Barnes, reinstated the title by sanad charter, giving the Thathanapaing nominal authority over internal administration of the Sangha in Upper Burma and over Buddhist ecclesiastical law. The Taunggwin Sayadaw was appointed, but the position was abolished after his death and no successor was ever appointed.
