Short answers, pulled from the story.
Bangkok's full ceremonial name begins Krungthepmahanakhon Amonrattanakosin Mahintharayutthaya and is listed in Guinness World Records as the world's longest place name at 168 letters. Composed of Pali and Sanskrit roots, it translates as the city of angels, great city of immortals, seat of the King, erected by Vishvakarman at Indra's behest. The city is officially known in shortened form as Krung Thep Maha Nakhon.
Bangkok has an estimated population of 11.4 million people as of 2024, which is 15.9 per cent of Thailand's population. Over 17.4 million people, about 25 per cent of the country, live within the surrounding Bangkok Metropolitan Region as of the 2021 estimate.
Bangkok grew rapidly with little urban planning, and zoning regulations were not fully implemented until 1992, leaving a road surface area of only 8 per cent compared to 20 to 30 per cent in most Western cities. It sits at an average elevation of just 1.5 metres above sea level on soft Bangkok clay, making it prone to flooding and subsidence, which reached 120 millimetres per year in 1981.
Bangkok became a capital when King Taksin established the Thonburi Kingdom there after Ayutthaya fell to the Burmese in 1767. The City Pillar was erected on the 21st of April 1782, when King Rama I moved the capital to Rattanakosin Island, the date regarded as the foundation of Bangkok as the capital.
Bangkok is called the City of Angels as a translation of Krung Thep, where krung means capital or king and thep derives from the Pali and Sanskrit deva, meaning deity or god. The name draws comparisons with Los Angeles, a comparably sized city with similar traffic issues. A tongue-in-cheek nickname, The Big Mango, echoes New York's Big Apple.
Bangkok was ranked the top tourism city in the world by Euromonitor International in 2024, welcoming a record 32.4 million visitors. It is known for landmarks such as the Grand Palace, Wat Phra Kaew, Wat Pho, and Wat Arun, its street life and markets like Chatuchak, and a sex tourism reputation that earned it the nickname Sin City of Asia.
