Bangkok

Bangkok, known in Thai as Krung Thep Maha Nakhon and colloquially as Krung Thep, is the capital and largest city of Thailand. The city occupies 1,568.7 square kilometres in the Chao Phraya River delta in central Thailand and has an estimated population of 9.1 million people as of 2024, 15.9% of the country's population.

Over 17.4 million people (25% of Thailand's population) live within the surrounding Bangkok Metropolitan Region as of the 2021 estimate, making Bangkok a megacity and an extreme primate city, dwarfing Thailand's other urban centres in both size and importance to the national economy.

Bangkok traces its roots to a small trading post during the Ayutthaya era in the 15th century, which eventually grew and became the site of two capital cities, Thonburi in 1767 and Rattanakosin in 1782.
