The ancient kingdom Tai Phuan
The kingdom was founded by Tai Phuan ethnic group or Phuan, a minor branch in Lao Thai language group. The territory has been estimated from Hua Phan to Kham Muon, the East of Lao country ; from the West of Nghe An to Quang Binh. This wonderland used to pay its tribute to more powerful countries like : Great Viet ( Dai Viet), Lan Xang, Ayutthaya , final French colonists, nowaday Laos.
Under leadership by King Le Nhan Tong, the kingdom was named as Tran Ninh province which used to belonged to Nghe An.
The Tai Phuan ethnic group or the minor Lao Thai group who followed Buddhism, removed from Yunnan highland to settle down in ( Ai Lao) Lao. They officially concentrated on Chum ricefields in Xieng Khoang highland.
Having lost their controls, Yuan Mongolian empire were unable to reign Yunnan highland because the Ming already set up their rules on this land. Therefore, Bon Man nation was established about in 1396.
By the end of the fourteenth century, this kingdom was reunited under King Fa Ngum dynasty. It was easier for the nobilities , Cam, to rule their country because they chose the capital in Xieng Khoang with limited popualation about 100000 citizens. To pay for their independence, the people of Bon Man paid a lot of tributes to powerful Lan Xang. Since then, the nobilities decided to follow the Later Le dynasty when Le Loi general became the king. From this time, Ai Lao ( the old name of Lao country) often attacked Dai Viet ( Great Viet country) but they mostly failed.
In 1478, King Le Thanh Tong defeated Cam Cong ( the leader of Bonman) , decided to connect BonMan , later became a part of Great Viet. He called it as Tran Ninh, the new part of Nghe An province.
In 1707, the nation Lan Xiang was divided in to three minor kingdoms : Vientian, Luang Phrabang and Champasak.
From 1735 – 1739, the Lord Le Duy Mat conquered Tran Ninh, arrested the leader of Tran Ninh but this rule did not last long when he failed
Gradually, In 1770, Siam – the kingdom in Recent Thai land, strengthened their reign . Therefore,this time Bon Man changed their rules to follow Siam, although, still paid tributes to Great Viet ( Dai Viet)
The Nguyen Tay Son put an end to the leaders of Bon Man because these leaders expected to attack Tay Son. By then, Bon Man was ruled by Nguyen Dynasty
Finally, the first King of Nguyen dynasty , Gia Long was not interested in ruling this land but lately his son who is Minh Mang,the next king reconquered this place Unluckily, French colonists put an end to this land when they reorganized to give them to Laos , a country in Indochina ( Laos, Cambodia va Vietnam). Nowsaday, Laos owns this territory
At present, the name Bon Man is just available on human history or who loves history.
