Raja was a Sri Lankan tusker elephant belonging to the Sri Dalada Maligawa, Kandy. Raja participated at the annual Esala procession in Kandy for around 50 years and was the sacred casket bearer of the final Randoli perehera for 37 years. He was one of the most celebrated elephants in Asia during his lifetime, and was world famous for his noble behavior. On 20 August 1986 former Sri Lankan President J. R. Jayewardene declared Raja as a national treasure, in recognition of his valuable services to the religion and culture of Sri Lanka.

The Kandy Esala Perahera also known as The Festival of the Tooth is a festival held in July and August in Kandy, Sri Lanka. This historical procession is held annually to pay homage to the Sacred Tooth Relic of Buddha housed at the Sri Dalada Maligawa in Kandy. A unique symbol of Sri Lanka, the procession consists of traditional local dances such as fire dances and performances in whip-dance garments. The festival ends with the traditional Diya-kepeema ritual, a water cutting ceremony which is held at the Mahaweli River at Getambe, Kandy.
