King Chulalongkorn wanted to make the people less subservient, thus, in 1873 after the coronation, he proclaimed that prostration in front of the king was to be abolished. Later, in 1905 he abolished slavery. This slave abolition was the most important royal contribution. The Slave Act was passed by King Rama V in 1905 to prohibit slave-trade. The King traveled extensively throughout the kingdom to personally investigate and share his subjects’ conditions and aspirations, often known in Thai as “Prapasstion”. It is very difficult to mention all of his numerous reforms. All the present-day ministries and departments owe their origin of his far-sighted concepts.
