It is believed that Loy Krathong is an ancient Brahmanic or Indic festival. Originally it was a ceremony where people paid their respects to three different gods known as Phra I-Suan (Shiva), Phra Narai (Vishnu) and Phra Phrom (Brahma).People would make lanterns using candles and paper, which would then be displayed in the homes of royalty, rich people or high-ranking officials.One hundred and fifty years ago, at the urging of King Mongkut (Rama IV), it was later adopted by Buddhists as a ceremony to honor the Buddha.
