It is a neat concept and particularly attractive to those doing the fighting and praying, who use it to justify the gross inequalities in society. But it is a concept that has been increasingly outdated since the twelfth century. Between 1333 and 1346 it is systematically shredded by the English longbowmen, who, although ranked among “those who work,” show that they are a far more potent military force than the massed charging ranks of “those who fight.” In those few years, “those who work” become “those who fight,” thereby threatening to make the old aristocracy redundant.
