According to the 2011 census, 59.4% of the population is Christian, 24.7% non-religious, 5% is Muslim while 3.7% of the population belongs to other religions and 7.2 did not give an answer.[209] Christianity is the most widely practised religion in England, as it has been since the Early Middle Ages, although it was first introduced much earlier, in Gaelic and Roman times. It continued through Early Insular Christianity. The largest form practised in the present day is Anglicanism,[210] dating from the 16th-century Reformation period, with the 1536 split from Rome over Henry VIII wanting to divorce Catherine of Aragon, and the need for the Bible in the English tongue. The religion regards itself as both Catholic and Reformed.
