The Black Death of 14th century Europe was caused by the spreading of the bacteria Yersinia Pestis on fleas carried by rats on trading ships from Asia. In Asia (where the plague had an even larger effect than it did in Europe), infected fleas would stay on rats, and the rats would board trading ships.
