Every year Thailand celebrates a holiday called “Chulalongkorn Day” on October 23rd. This leads some people to ask, “What did King Chulalongkorn do?” Let’s answer that question in detail now.

King Chulalongkorn of Siam is also known as Rama V. His 42 year reign lasted from 1868 – 1910. He is a monumental figure of history. His achievements and accomplishments are vast, as he was instrumental in bringing Siam (Thailand) from a feudal state into the modern age. Without his stewardship it is unlikely that Thailand would have been able to navigate the challenges of the 19th and early 20th centuries as well as it did.

King Chulalongkorn’s Key Achievements include:

Abolition of Slavery: He abolished slavery in Siam in 1905, becoming one of the first countries in Asia to do so.

Administrative Reforms: He undertook major administrative reforms, centralizing power and modernizing the government structure. He introduced ministries, a modern legal system, and restructured the military.

Modernization of Education: He promoted education by establishing the first schools, inviting foreign experts to teach, and sending Siamese students abroad to study in Europe. This helped lay the groundwork for modern education in Thailand.

Financial Reforms: He implemented fiscal reforms that stabilized the economy and improved tax collection, leading to increased revenue for the state.

Legal Reforms: He codified laws and established a legal framework, promoting fairness and justice within the legal system.

Modernizing Institutions: He modernized the Siamese military, creating a standing army and navy, and implemented changes to the social hierarchy, reducing the power of traditional nobility.

Diplomacy and Sovereignty: King Chulalongkorn skillfully navigated international diplomacy, successfully preventing colonization by European powers. Siam remained the only Southeast Asian country not colonized during the European scramble for Asia.

Cultural Preservation: While modernizing the country, he also sought to preserve Thai culture and traditions, encouraging the study of history, arts, and literature.

Public Welfare: He initiated public welfare programs, including healthcare improvements and disaster relief efforts, demonstrating his concern for the well-being of his subjects.
