the years 1432 through 1434 were known as "the hungry years" in czech lands as they faced climatic issues for the duration of the hussite wars. the hussite wars were fought in bohemia between the followers of the executed jan hus, a renowned contributor to the protestant movement. this set of wars was one of the first known military actions fought with hand-held firearms. the final two years of this fourteen-year set of wars sparked an increase in the price of grain. at one point grain was six times the price it had been prior to the wars. people in czech lands were unable to afford grain until the price returned to an affordable rate.
