Background and detail

Background. Charles-Marie David de Mayréna was a former French government official with a dubious history involving alleged embezzlement. In 1888, he owned a plantation in French Indochina. The King of Siam began claiming territories near those held by the French, prompting nervous colonial administrators to authorize Mayréna to lead an expedition into the interior to negotiate treaties with local tribes.

Formation. Mayréna was elected King by the chiefs of the Bahnar, Rengao, and Sedang tribes. He established his capital at the village of Kon Gung, also known as Pelei Agna or Great City. On 3 June 1888, he assumed the regnal name Marie the First, King of the Sedang, marking the formal formation of the kingdom in the northern Central Highlands.

Diplomatic Efforts. Following its formation, Mayréna sought official diplomatic recognition for his kingdom. He offered to cede the Kingdom of Sedang to the French Third Republic in exchange for monopoly trade rights. He also hinted that the Prussians were interested in the territory if the French declined, attempting to leverage international interest to secure his position.
