A History Mystery! A teaching resource for KS2 history investigating the question: Did Bloody Mary deserve her nickname? An excellent activity to use when teaching the Tudors. History Mysteries are a series of teaching resources aimed at KS2, which seek to introduce children to the skills of a historian. Each one poses a question, the answer to which, in many cases, has no consensus amongst historians! Children are presented with historical context and a range of sources to help them make their own minds up.
