Answer:
What is being emphasized in the phrase is the enormous power that Napoleon had at the time in Europe.
Explanation:
From 1807 to 1812, Napoleon managed to conquer large areas of Europe, including Germany, which was the Holy Roman Empire at the time, a political entity that he himself dissolved, Italy, parts of Spain, parts of the Low Countries, and some areas in Eastern Europe.
Napoleon then, tried to conquer Russia, but this proved to be fatal to him, because of the large landmass and the harsh winter. His campaign in Russia would be the beginning of his demise.
