it might be observed that Guy Fawkes' Day is finally declining, having lost its connection with politics and religion. But we have heard that many times before." In 2012 the BBC's Tom de Castella concluded: Similarities with other customs Historians have often suggested that Guy Fawkes Day served as a Protestant replacement for the ancient Celtic festival of Samhain or Calan Gaeaf, pagan events that the church absorbed and transformed into All Hallow's Eve and All Souls' Day. In The Golden Bough, the Scottish anthropologist James George Frazer suggested that Guy Fawkes Day exemplifies "the recrudescence of old customs in modern shapes". David Underdown, writing in his 1987 work Revel, Riot, and Rebellion, viewed Gunpowder Treason Day as a replacement for Hallowe'en: "just as the early church had taken over many of the pagan feasts, so did Protestants acquire their own rituals, adapting older forms or providing substitutes for them". While the use of bonfires to mark the occasion was most likely taken from the ancient practice of lighting celebratory bonfires, the idea that the commemoration of 5 November 1605 ever originated from anything other than the safety of James I is, according to David Cressy, "speculative nonsense". Citing Cressy's work, Ronald Hutton agrees with his conclusion, writing, "There is, in brief, nothing to link the Hallowe'en fires of North Wales, Man, and central Scotland with those which appeared in England upon 5 November." Further confusion arises in Northern Ireland, where some communities celebrate Guy Fawkes Night; the distinction there between the Fifth, and Halloween, is not always clear. Despite such disagreements, in 2005 David Cannadine commented on the encroachment into British culture of late 20th-century American Hallowe'en celebrations, and their effect on Guy Fawkes Night: In Northern Ireland, bonfires are lit on the Eleventh Night (11 July) by Ulster Protestants. Folklorist Jack Santino notes that the Eleventh Night is "thematically similar to Guy Fawkes Night in that it celebrates the establishment and maintenance of the Protestant state". Another celebration involving fireworks, the five-day Hindu festival of Diwali (normally observed between mid-October and November), in 2010 began on 5 November. This led The Independent to comment on the similarities between the two, its reporter Kevin Rawlinson wondering "which fireworks will burn brightest". In other countries Gunpowder Treason Day was exported by settlers to colonies around the world, including members of the Commonwealth of Nations such as Australia, New Zealand, Canada,
