The Rattanakosin Period refers to the era in Thai history that began in 1782 when King Rama I established the city of Bangkok as the capital of the Kingdom of Siam. This period is marked by significant cultural, political, and economic developments, including the consolidation of the monarchy and the establishment of a centralized government. During the Rattanakosin Period, the arts flourished, leading to the creation of distinctive Thai architecture and literature. The period also saw the introduction of Western influences, particularly in education and technology, which helped modernize the country while preserving traditional Thai culture.
