Rama VII, King (Rattanakosin Kingdom) : All Data

Rama VII, also known as King Prajadhipok, was the ruler of the Kingdom of Thailand from 1925 to 1935. During his reign, Thailand faced significant political changes, including the Siamese Revolution of 1932, which led to the establishment of a constitutional monarchy. Although Rama VII's reign did not directly coincide with any major wars, it was a period of political unrest and social transformation. The most notable conflict during this time was the Franco-Thai War, which occurred from 1940 to 1941, after Rama VII's abdication.
