According to Wikipedia, “Mercantilism is an economic policy that is designed to maximize the exports and minimize the imports for an economy. It promotes imperialism, colonialism, tariffs and subsidies on traded goods to achieve that goal.” Mercantilism is pretty much just an economic practice used to augment state power at the expense of other countries. A historic example of this would be the Sugar Act of 1764. This was a time where the colonists were made to pay higher tariffs and duties on the imports of foreign-made sugar brought to them by other countries.
The War of the Spanish Succession lasted from 1701 to 1750. The death of childless King Charles II of Spain triggered the war. In Charles’ will, he left the throne to Philip, Duke of Anjou, grandson of King Louis XIV of France. However, England, Holland, Prussia and Austria saw this as jeopardizing the balance of power in Europe. They formed a group called the Grand Alliance and tried to put Habsburg Archduke Charles of Austria on the throne instead of Philip. Eventually war broke out, but it eventually stopped with a negotiated end with Philip on the throne.
According to Wikipedia, “The Edict of Nantes was signed in April 1598 by King Henry IV and granted the Calvinist Protestants of France, also known as Huguenots, substantial rights in the nation, which was in essence completely Catholic. In the edict, Henry aimed primarily to promote civil unity.” The Edict of Nantes put a temporary stop to the religious wars between Roman Catholics and Protestants which had torn France apart ever since the 1560s.
