 The Past

Since the 10th century, Ubon Ratchathani, or simply Ubon, was part of the Khmer Empire until the Kingdom of Ayutthaya conquered it. Towards the end of the 18th century, Laotians immigrated to the northern banks of the Mun River and founded the provincial capital. The Laotian influence is evident in the architectural structure of some of the city's religious buildings. This incident was told in the provincial seal which features a pond with a lotus flower and leaves in a circular frame. It symbolizes the ancient community of the people who fled the massacre of King Siriboonsarn of Vientiane and came to settle in Nong Bua Lam Phu Province in 1779 during the reign of King Thonburi. This community was established as a province with the name Ubon Ratchathani Srivanalai in 1792 during the reign of King Rama I, the first king of the Chakri Dynasty.

During the reign of King Rama V, Ubon Ratchathani was annexed to Lao Kao town. Later in 1899, the area was under the supervision of Northeastern Monthon, with Ubon Ratchathani serving as an administrative hub. In 1900, the name was changed to Monthon I-San. When the Monthon system was abolished, the city has become Ubon Ratchathani province. During the Vietnam War, Ubon encountered expansive growth due to its proximity to an American air base.

 The Present

Today, the province is the largest and one of the most important provinces in northeastern Thailand. Due to the large number of fascinating temples dotting the city, Ubon is a place of pilgrimage at the beginning of Buddhist Lent. Aside from the numerous attractions, festivals and holidays are celebrated with a unique Ubon flair.

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.
