The Burmese Empire was a historical kingdom that existed in Southeast Asia, primarily in what is now modern-day Myanmar. It reached its height during the 11th to 13th centuries under the rule of the Pagan Dynasty, which unified various smaller states and established a centralized government. The empire is known for its impressive architectural achievements, including the construction of thousands of temples in the city of Bagan. The empire played a significant role in the spread of Buddhism throughout the region, influencing culture, art, and religion. However, it faced challenges from neighboring kingdoms and eventually declined in the 13th century, leading to the rise of other powers in Southeast Asia.
