What were Napoleon's foreign policies?Information needed for an essay. Thanks!
You mean besides conquering everything in sight? Outside of literally working to bring the whole of Europe under his rule, Napoleon generally used any means he could, including his relatives, marriage to key royalty in other countries, and threats to manage his neighbors and allies.
One notable policy of Napoleons was the re-institution of slavery in the French colonies and subsequently was defeated in Haiti as his expeditionary force was unable to contend with an army of slaves. This, some speculate, led him to decide that trying to maintain some of these colonies was not worth the expense and he then looked favorably upon the sale of the Louisiana Purchase to the United States.
While the first answer sees Napoleon in a very negative and predatory way, I think that you can argue that Napoleon's foreign policies were not the way he characterizes them (or not completely, at least).
Napoleon was trying to spread the ideas of the French Revolution, in my opinion. You can see that he was doing this by the fact that he imposed the values of that revolution in every country that he conquered.
This is one reason why the rest of Europe was arrayed against him. They saw him as a threat to the stability of their countries and their social systems.
