Farm workers were so rare that they were able to demand wages at double or triple the pre-plague rate. The pre-plague had been 4d.- 6d. daily for masons, carpenters, plasterers, and tilers and 3d. for their laborers. These laborers could buy 12 cheap loaves, 3 gallons of ale, and a gallon of cheap wine or half a pair of shoes. Prices did not go up nearly as much as wages. Villeins relinquish their tenements, and deserted their manors, to get better wages elsewhere. They became nomadic, roaming from place to place, seeking day work for good wages where they could get it, and resorting to thievery on the highways or beggary where they could not. The Robin Hood legends were popular among them. In them, Robin Hood is pure outlaw and does not contribute money to the poor. Nor does he court Maid Marion. They spread political songs among each other, such as: "To seek silver to the King, I my seed sold; wherefore my land lieth fallow and learneth to sleep. Since they fetched my fair cattle in my fold; when I think of my old wealth, well nigh I weep. Thus breedeth many beggars bold; and there wakeneth in the world dismay and woe, for as good is death anon as so for to toil." Groups of armed men took lands, manors, goods, and women by force. The villeins agreed to assist each other in resisting by force their lords' efforts to return them to servitude. A statute of laborers passed in 1351 for wages to be set at the pre-plague rates was ineffectual. Justices became afraid to administer the law. Villeins, free peasants, and craftsmen joined together and learned to use the tactics of association and strikes against their employers. The office of Justice of the Peace was created for every county to deal with rioting and vagrants. Cooperation by officials of other counties was mandated to deal with fugitives from its justice. The Black Death visited again in 1361 and in 1369. The Black Death reduced the population from about 5 million to about 2 1/2 million. It was to rise to about 4 million by 1600. When there were attempts to enforce the legal servitude of the villeins, they spread rhymes of their condition and need to revolt. A secret league, called the "Great Society" linked the centers of intrigue. A high poll tax, graduated from 20s. to 12d., that was to be raised for a war with France, touched off a spontaneous riot all over the nation in 1381. This tax included people not taxed before, such as laborers, the village smith, and the village tiler. Each area had its own specific grievances. There was no common political motive, except maladministration in general.
