The correct answer to this open question is the following.
I am going to pick the two most important revolutions in that period. First of all, the American Revolutionary War and then the French Revolution.
To me, one difference between the two revolutions movements is the following. On one hand, the American Revolution was a rebellion to get independence from another country, in this case, Great Britain, a nation that had its own political and economic interests in the North American colonies. On the other hand, the French Revolution was an armed revolution from the poorest social classes in France that lived unders¿ hash economic conditions and started the rebellion against the King of France.
