A short history of the Chao Phraya River

The Chao Phraya River has been witness to the rise of ancient civilizations, serving as the cradle of early settlements in Southeast Asia. From the 7th to the 11th century, it played a pivotal role in the Mon kingdom and the Dvaravati civilization. The river's importance continued through the Lavo kingdom, shaping the foundations of the Ayutthaya Kingdoms. In 1782, the establishment of Rattanakosin (Bangkok) on the east bank further solidified the river's significance, providing protection against Burmese invasions and laying the groundwork for modern Thailand, formerly known as Siam. The Chao Phraya's historical currents run deep, mirroring the dynamic evolution of the region.

Initially chosen for its fertility and abundant fish by early settlers, its historical journey unfolded as King Taksin, post the fall of Ayutthaya, established his new capital, Thonburi, on the western banks. In 1782, King Rama I deemed the eastern banks more favorable, founding modern Bangkok and embellishing it with enchanting temples. Today, the Chao Phraya is a vital transportation route, hosting a network of river buses, ferries, and water taxis, facilitating over 15 boat lines in the city.
