Human habitation of the province dates back to the Neolithic era, when early inhabitants lived in the area along the Panthong river in modern day Phan Thong district. During the
Dvaravati period, the city of Mueang Phra Rot (Phra That Noen That) was established close to the mouth of the Bang Pakong river in modern-day Phanat Nikhom District. The city was in the shape of an irregular rectangle and was surrounded by a moat. Mueang Phra Rot was established from the 600s to the 1000s and had goods imported from the
Tang and
Song dynasties and from either
Persia or
lower Mesopotamia. To the east of Phra Rot was Mueang Sri Phalo in modern-day Nong Mai Daeng, which was established near the end of Phra Rot in the 1000s.
Late 19th century to present In the reign of King Nangklao,
Rama III, Phra Intha-asa, The Governor of Phanat Nikhom I (Princely member of Nakhon Phanom royal family) took many immigrants (Nakhon Phanom Laotians, Named Lao Asa Pak Nam) from Samut Prakan and New Nakhon Phanom Laotians to Phanat Nikhom. The Siamese King at the time allowed them to establish a habitat between Chonburi and Chachoengsao (Named Phanat Nikhom in the present). In 1892,
Ko Sichang, an island off the mainland, served as a holiday point for
King Chulalongkorn and his wife
Queen Saovabha Phongsri. Chulalongkorn later built a summer palace called "
Phra Chuthathut Palace" named after his son,
Prince Chudadhuj Dharadilok, who was born on Ko Sichang. During the
Franco-Siamese crisis of 1893, the island was occupied by the French. During this time, the island was a part of
Samut Prakan province before being transferred to Chonburi province on 1 January 1943 as a minor district (
king amphoe) in Si Racha district. Ko Sichang became its own district on 4 July 1994. Following the end of World War II, coastal towns particularly Ang Sila witnessed an influx of Teochew Chinese migrants. The Vietnam War would also cause an influx of American G.I.s to arrive, particularly in Pattaya. This would go on to lead Chonburi province to become popular among foreign tourists. == Symbols ==
