The Pagan Dynasty was a powerful kingdom in what is now Myanmar, flourishing from the 9th to the 13th centuries. It is known for its significant contributions to culture, religion, and architecture, particularly through the construction of thousands of temples and stupas in the region of Bagan. The dynasty played a crucial role in the spread of Buddhism in Southeast Asia. Under the Pagan Dynasty, the region experienced economic growth and political stability, which facilitated trade and cultural exchange. The dynasty's rulers, such as Anawrahta, unified various tribes and established a centralized government. The decline of the Pagan Dynasty began in the 13th century, leading to its eventual fall to the Mongol Empire.
