Ubon Ratchathani province

Mekong River in Khong Chiam

At Khong Chiam the Mun River, the biggest river of the Khorat Plateau, joins the Mekong, which forms the northeastern boundary of Thailand with Laos. It is called "Maenam Song Si" or the "Mun River alluvium" because the brown water from Mekong River mixes with the blue water of the Mun. It is about 84 km (52 mi) from Ubon Ratchathani city centre.[5]

The area in the Dângrêk Mountains where the borders of the three countries, Thailand, Laos, and Cambodia meet is promoted as the "Emerald Triangle", in contrast to the "Golden Triangle" in the north of Thailand. "Emerald" refers to the largely intact monsoon forests there. The total forest area is 2,808 km² (1,084 sq mi) or 18 percent of provincial area.[2]

The city was founded in the late 18th century by Thao Kham Phong, descendant of Phra Wo and Phra Ta, who escaped from King Siribunsan of Vientiane into Siam Kingdom during the reign of King Taksin the Great. Later Thao Kham Phong was appointed to be “Phra Pathum Wongsa" The first ruler of Ubon Ratchathani. In 1792, Ubon Ratchathani became a province, and was also the administrative center of the monthon Isan.

Until 1972, Ubon Ratchathani was the largest province of Thailand by area. Yasothon was split off from Ubon Ratchathani in 1972, followed by Amnat Charoen in 1993.

Before it became a province. Ubon Ratchathani was the administrative center of the monthon Isan, of which monthon Ubon was split off. In 1925 it became part of monthon Nakhon Ratchasima, with the abolishment of the monthon in 1933 the province became a first level subdivision of the country.

The provincial seal shows a lotus flower in a pond. This alludes to the meaning of the name of the province, which translates to 'royal city of the lotus flower'. The provincial flower is the lotus (Nymphaea lotus). The provincial tree is the Yang-na (Dipterocarpus alatus). Black-eared catfish (Pangasius larnaudii) is the provincial aquatic animal.
