|General Information |
|Ubon Ratchathani is one of the north-eastern provinces of Thailand, and the country's easternmost. Ubon is about 500 km away from Bangkok. Ubon Ratchathani Province covers a total area of 15,744.85 square kilometers, with Amnat Charoen Province to the north, the Banthat Mountain Range along the border of the Kingdom of Cambodia to the south, the Mekhong River and Lao People's Democratic Republic to the east, and Yathothon and Si Sa Ket Provinces to the west.|
Located in the Korat Basin about 68 meters (227 feet) above sea level, most of Ubon Ratchathani is a plateau sloping to the east to meet the Maekhong River, a border between Thailand and the Lao Peoples Democratic Republic. Other major rivers in the area are the Chee River, Moon River, Lum Saybok River, Lum Domeyai River and Lum Domenoi River. There are some high mountain ranges in the south such as Bantad Range and Phanom Dongrak Range which border Ubon Ratchathani and the Lao Peoples Democratic Republic and the Kingdom of Cambodia.
At Khong Chiam, the Mun river, the biggest river of the Khorat Plateau, joins the Mekong, which forms the north-eastern boundary of Thailand with Laos. The area 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. The Emerald refers to the large intact monsoon forests there.
The Kha and the Suai, two local tribes, had moved from Si Sattanakanahut to this area before the Rattanakosin Period. During the reign of King Rama I, the King thought of locating the people scattered around because of war into one area. Therefore, any leader who could gather the greatest number of people and establish a secure community would be promoted to the rank of Chao Muang or Chief. For this reason, in 1786, Thao Kham Phong, who had led a group of his people to settle in the Huai Chaeramae area on a plain on the bank of the Mun River, was promoted to the rank of Chief. Later, when he helped the Thai troops to attack Nakhon Champasak, he was promoted to the rank of Phra Pathum Worarat Suriyawong and became Chao Muang or Governor of Ban Chaeramae, which was upgraded to the status of a province called Ubon Ratchathani. Later, the city was moved to a new site at Dong U-Phung, which is the site of the present city with seven other towns as satellites.
During the reign of King Rama V, before the reform of the provincial administration which divided the kingdom into Monthon (circle), Changwat (province), and Amphoe (district), Ubon Ratchathani was annexed to Lao Kao town. Later in 1899, the name of the area was changed to the Northeastern Monthon with Ubon Ratchathani as its administrative center, and the name was changed again in 1900 to Monthon I-San.
Because of the Depression in 1915, the status of Monthon Ubon Ratchathani was reduced to only a province in Monthon Nakhon Ratchasima in 1933, the division of the kingdom into Monthon was abolished and the city has been known as Ubon Ratchathani from that time on.
