The Pagan Kingdom was a historical kingdom located in present-day Myanmar, flourishing from the 9th to the 13th centuries. It is known for its significant contributions to the spread of Buddhism in the region, with thousands of temples and stupas built during its peak. The kingdom's capital, Bagan, became a major center for trade and culture. The Pagan Kingdom was ruled by a series of kings, with notable figures like Anawrahta, who unified the region and established Theravada Buddhism as the state religion. The kingdom eventually declined due to internal strife and external invasions, particularly from the Mongols in the 13th century.
