The monument was erected in June 1941 to commemorate the Thai victory in the Franco-Thai War, a brief conflict waged against the French colonial authorities in Indo-China, which resulted in Thailand annexing some territories in western Cambodia and northern and southern Laos. These were among the territories which the Kingdom of Siam had been forced to cede to France in 1893 and 1904, and patriotic Thais considered them rightfully to belong to Thailand.
