The black death which swept
through Europe was carried via the trade routes. Caused by rats
and fleas the disease reached Ireland in 1348, devastating the
population. It killed many people, others fearful of catching
it fled to England.
During this period severe
restrictions were placed on travel in an attempt to contain
it. This led to widespread labour shortages, and ultimately
to shortages of food. It is estimated that approximately one
third of the population died during the outbreak.
