In 1932, a revolution changed the political system into a constitutional monarchy.
Bangkok became a province and Thonburi on the west bank became another province. In 1971, the two provinces were joined under the name of Nakhon Luang Krung thonburi. One year later, the form of local government in the city was reorganized and the province got a new name as Krung Thep Maha Nakhon or popularly called Krung thep for short. The name is still used today, while internationally Krung thep is known as Bangkok, The name “Bangkok” formerly referred to a small fishing village. Later, Bangkok’s area expanded into communities on both sides of the Chao Phraya River.
