No American Revolution

In this timeline, the main point of divergence is that the United States lost its war of independence. As a consequence, the main differences from our timeline are:
 * The French Revolution as we know never happened. Instead, revolutionaries used England's example and created a Parliament to restrain the King's power.
 * Napoleon never became Emperor. As a result, Napoleonic Wars never happened, and the Holy German Empire still exists. It's now a federal executive constitutional monarchy.
 * Since Napoleonic Wars did not happen, so King John VI of Portugal never transferred the court to Brazil. As a result, Brazil now forms a Royal Union with Portugal, in the United Kingdom of Brazil Portugal and the Algarves, which is a Federal Parliamentary Monarchy.
 * Spanish America got its independence and formed seven separate realms: the Empire of New Spain, the Kingdom of Peru, Kingdom of Chile, Kingdom of New Granada, Kingdom of Venezuela, Kingdom of Guatemala and Empire of Argentina.
 * French territories in North America are now autonomous parts of France.
