context_page_description: The Royal Standard of Thailand is the official flag of the King of Thailand. The present form was adopted in 1910 under Vajiravudh, superseding the first Royal Standard created by Mongkut in 1855. In 1979, the designs were codified by law; specifically in Article 2 of the Flag Act of 1979, which also regulated Thailand's other flags. The standard is currently used by Maha Vajiralongkorn, also known as Rama X, since 2016.
