Protestant

Originally kickstarted by Henry VIII who was originally catholic and wanted to divorce his wife (Catherine of Aragon) but the annullment was not allowed by the pope (who was being held prisoner by Charles V of the Holy Roman Empire at the time). After falling for Anne Boleyn king Henry excommunicated himself from the catholic church and a parliamnet act was passed known as the 'act of succession' which put Henry as the head of the church of england, which is to this day officially protestant (although this has alternated between catholisism and protestantism over the centuries and has sparked many feuds between the two religions. Perhaps most notably the gunpowder plot on the houses of parliament and of course the colonisation and 'thourough' by Sir Thomas Wentworth of Northern Ireland which still has massive political repocusions.)
