Thai King stages grand river procession to celebrate Queen Suthida's 48th birthday

King Maha Vajiralongkorn recently staged a grand royal barge procession on the Chao Phraya River in Bangkok to celebrate Queen Suthida's 48th birthday.

Although Queen Suthida's birthday falls on June 3, King Maha Vajiralongkorn (Rama X) chose to celebrate the occasion on Nov. 6 during the Buddhist Kathin festival, which marks the end of the monks' annual retreat, according to the Government Public Relations Department.

The procession set off from Wasukri Pier on the afternoon of Nov. 6, traveling approximately 4 km to Wat Arun. The flotilla comprised 52 barges manned by 2,200 oarsmen, arranged into five columns and three lines spanning 1,280 meters in length and 90 meters in width.

Their Majesties the King and Queen traveled aboard the Suphannahong, the principal royal barge. Her Royal Highness Princess Sirivannavari Nariratana Rajakanya and His Royal Highness Prince Dipangkorn Rasmijoti joined the procession aboard the Royal Barge Anekkachatphutchong, alongside Chaokhun Phra Sineenatha Bilasakalyani.

The Suphannahong, also known as the Golden Swan Royal Barge, was launched in 1911 during the reign of King Rama VI. It was built to replace an earlier royal barge commissioned in 1782 by King Rama I, founder of the Chakri dynasty. Its bow features a carved golden swan—known in Hindu mythology as the hamsa, the divine mount of the god Brahma—according to Thailand’s government portal.

Large crowds of local residents and visitors gathered along the riverbanks to watch the procession pass.

The event marked Queen Suthida's completion of her fourth 12-year life cycle, based on the Eastern zodiac system. In Thailand, turning 48 is considered a highly significant milestone traditionally accompanied by large-scale ceremonies.

The Royal Barge Procession originated from ancient naval battle flotillas led by the king during times of war. Historically, it demonstrated the monarch's might as the defender of the kingdom's sovereignty and territorial integrity, while showcasing the power of the armed forces. Today, it serves as a ceremonial waterborne procession reserved for the king's river journeys during royal ceremonies.

As a vital piece of Thailand's cultural heritage, the procession reflects a traditional Thai way of life deeply intertwined with waterways and boats for centuries.

Since King Rama X ascended the throne in 2016, Thailand has held only three such commemorative river ceremonies. These grand occasions are sometimes accompanied by the issuance of new banknotes, much like when the Bank of Thailand issued commemorative bills for the 84th birthday of the late King Rama IX in 2011.

Born in 1978, Queen Suthida is the fourth wife of King Maha Vajiralongkorn. She married the king in 2019, just days before his coronation.

She recently made headlines after becoming the first reigning queen in the world to fly a fighter jet solo.
