It also spread from fleas upon rats aboard merchant ships, and i â¦ s believed to have spread from Sicily.
The plague is believed to be the cause of the Black Death that swept through Asia, Europe, and Africa in the 14th century and killed an estimated 50 million people. This was about 25% to 60% of the European population. Because the plague killed so many of the working population, wages rose due to the demand for labor.
