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.
