Answer:
The question is referring to <em>The black Death by Margarent Gushne 2018</em>
Explanation:
In the first paragraph the author cites <em>''Their arrival would change the course of European history''</em>
<em />
The Plague was introduced into Sicily from a ship coming in from Crimea. While everyone infected on the ship died within a few days, the contagious disease had already spread among everyone who had come in contact with them.
At the time, the modern region of Italy was known for trade and the import and export of goods from all over the world. The Italian merchants took the disease with them and within a couple of weeks, it had spread across all of Europe.
Some estimates put the number of dead as high as 50 million people. When the dust settled, there were more jobs than the number of people and while before people lived on serfdom, the system, especially in England was completely broken down.
Land owners were looking for people and started paying them to work and the peasant and middle class began to have more social mobility and political influence.
It took over 200 years before Europe's population went back to pre-plague days but until then, democracy was already creeping in.
