History. Television documentaries Dinosaurs, Myths and Monsters In February 2011, Holland wrote and presented Dinosaurs, Myths and Monsters, a BBC Four television programme. It explored the influence of fossils on the mythology of various cultures throughout history, including the ancient Greeks and Native Americans. Islam: The Untold Story In August 2012, Holland produced and presented a documentary for Channel 4 television titled Islam: The Untold Story, which questioned Islamic doctrine that maintains Muhammad founded the religion in Mecca in the 7th century, and that the Quran was transmitted, in full, directly to Muhammad by Allah (God) via the angel Gabriel, rather than being written by a person or persons. Holland argued that there is very little contemporary historical evidence about the life of Muhammad, with no mention of him at all in historical texts until decades after his death, and no mention of Mecca in any datable text relating to him until over a century after he died. He concluded that it is much more likely that Islamic theology developed gradually over several centuries as the Arab Empire expanded, and that descriptions of Muhammad's home more closely resemble what is now southern Israel than Mecca. Holland said the program provoked "a firestorm of death threats" against him. Islam: The Untold Story generated more than 1,200 complaints in total to Ofcom and Channel 4, though Ofcom found there was no breach of its broadcasting code to investigate. A planned screening of Islam: The Untold Story before an audience of historians was cancelled, due to security concerns over threats received by Holland as a result of the documentary. Several religious scholars, including Dr. Jenny Taylor, founder of the Lapido Media Centre for Religious Literacy in World Affairs, and Dr. Keith Small of the International Qur'anic Studies Association, defended Holland and the right of historians to critically examine the origin stories of religions. Writing on the Channel 4 website, Holland responded to the criticism by saying that the origins of Islam is a "legitimate subject of historical enquiry" and that his documentary was "a historical endeavour and is not a critique of one of the major monotheistic religions". Isis: The Origins of Violence In 2017, Holland revisited the topic of Islam by writing and presenting another documentary for Channel 4. Isis: The Origins of Violence looked at the militant terror group ISIS and argued that they use Islamic doctrine to inform and justify
