The Pyu city-states were a group of ancient urban centers located in present-day Myanmar. They flourished between the 1st and 9th centuries CE and were known for their advanced culture, trade, and architecture. The city-states, including Sri Ksetra, Beikthano, and Halin, played a significant role in connecting India and China through trade routes. These city-states were characterized by their unique brick structures, stupas, and inscriptions in the Pyu language. The Pyu people practiced Buddhism, which influenced their art and culture. The decline of the city-states began around the 9th century, leading to the rise of the Burmese kingdoms.
