The Grammarians' War (1519–1521) was a conflict between rival systems of teaching Latin. The two main antagonists were grammarians and schoolmasters William Horman and Robert Whittington. The War involved Latin primers called Vulgaria, which were thus named because they contained "vulgar" (in the 16th century sense, i.e. everyday and common) sayings or phrases that schoolchildren were expected to use in normal life, such as "Sit away or I shall give thee a blow." and "Would God we might go play!".
