This excerpt is the opening of the Ordinance of Laborers, passed in 1349 in England. It was a reaction to the large number of deaths caused by the plague.
[A] great part of the people, and especially of workmen and servants, late died of the pestilence [plague], many seeing the necessity of masters, and great scarcity of servants, will not serve unless they may receive excessive wages, and some rather willing to beg in idleness, than by labor to get their living; we, considering the grievous incommodities [problems], which of the lack especially of ploughmen and such laborers may hereafter come, have upon deliberation and treaty with the prelates and the nobles, and learned men assisting us, of their mutual counsel ordained: That every man and woman of our realm of England ... able in body, and within the age of threescore years [under 60], [who is not a landowner or engaged in a trade], be required to serve, ... and take only the wages...which were accustomed to be given in … the twentieth year of [King Edward III’s] reign of England [1347], or five or six other common years next before [the previous five or six years].
