Holi (Hindi: होली) is a religious spring festival celebrated by Hindus. It is primarily observed in India, Bangladesh, Pakistan, Nepal, and countries with large Indic diaspora populations following Hinduism, such as Suriname, Malaysia, Guyana, South Africa, Trinidad, United Kingdom, United States, Mauritius, and Fiji. It is also known as Phagwah and Festival of Colours, or as Doḷajāta (Oriya: ଦୋଳଯାତ) in Orissa and Dol Jatra (Bengali: দোলযাত্রা) or Basantotsav ("spring festival") (Bengali: বসন্তোৎসব) in West Bengal. The most celebrated Holi is in the Braj region, in locations connected to the Lord Krishna: Mathura, Vrindavan, Nandagaon, and Barsana, which become tourist destinations during the season of Holi. Large parts of South India, however, do not celebrate Holi with the same fervour.

In Vaishnavism, Hiranyakashipu is the great king of demons, and he had been granted a boon by Brahma, which made it almost impossible for him to be killed. The boon was due to his long penance, after which he had demanded that he not be killed "during day or night; inside the home or outside, not on earth or in the sky; neither by a man nor an animal; neither by astra nor by shastra". Consequently, he grew arrogant and attacked the Heavens and the Earth. He demanded that people stop worshipping Gods and start praising respectfully to him.
