 This view was reinforced by events elsewhere that demonstrated that Reformed religion was under threat, such as the 1572 Massacre of St Bartholomew in France and the Spanish Armada in 1588.These views were popularised through the first Protestant histories, such as Knox's "History of the Reformation" and George Buchanan's "Rerum Scoticarum Historia".This period also saw a growth of a patriotic literature facilitated by the rise of popular printing.
