Definitely the longest update yet, sorry for the wait guys.
In 1861 the Empire of France sent troops to the newly-founded Kingdom of Araucanía and Patagonia. This was part of French Emperor Napoleon III’s initiative to establish an Empire in the Americas. The South American state began with little semblance of control over the territories it claimed, a loose confederation of Mapuche tribes uniting behind Orélie-Antoine de Tounens, a French lawyer. It was Orélie-Antoine de Tounens’ nationality that attracted the attention of Napoleon III.
The intervention began with shipments of money and weapons to prop up the Mapuche forces resisting Chilean and Argentinian expansion. However, it became clear that it more would be needed, Napoleon III authorized deployment of troops in Patagonia. These reinforcements repeatedly crushed Chilean and Argentinian attempts to advance further southward. This allowed Araucanía and Patagonia to conquer the southernmost territories of Chile, and take Argentinian territories it had already claimed. Following the end of the conflict, the Kingdom of Araucanía and Patagonia became a French client state.

The second phase of France’s expansion in Latin America was in the Empire of Brazil. Seeking a counterbalance to France’s new enemies in Chile and Argentina, France began a diplomatic offensive in Brazil. They brought the Empire into their sphere of influence through a series of economic agreements and royal marriages, and formed a strong alliance. These successes in South America as well as other parts of the world strengthened the French position in Europe.
The first flexing of French power in Europe came with the purchase of Luxembourg. While it appeared that Prussia was going to contest this move, eventually French diplomats were able to soothe things through non-territorial concessions with the Prussians. This placed France in a much better position against the newly-formed North German Federation, and France was able to prepare for a potential conflict with the Federation. The spark that ignited the fire of conflict between these nations came from Spain.
After a crisis began because of the search for a new Spanish king. The Spanish offered the throne to the German prince Leopold of Hohenzollern-Sigmaringen, but French pressure and fear over a German-Spanish alliance forced the Germans to back down. German Chancellor Otto Von Bismarck, however, used the opportunity to goad France into declaring war. Today it is recognized that Bismarck was likely attempting to use the conflict to unify Germany, but we will never know for sure.
The Franco-Prussian war began with a massive French offensive into the North German Federation through Luxembourg. This move helped reduce the Prussian advantage, their forces were well organized and equipped, but their strategy was largely based on offensive maneuvers, and weren’t prepared to go on the full defensive. Bismarck's decision to goad France into attack, while necessary to get the support of the south German states, also allowed France to prepare and mobilize their forces. All these factors allowed the French to largely overcome the Prussian advantage.
The French drove into Prussia, and despite dogged Prussian resistance reached the Rhine. This caused the collapse of the Prussian armies, and the withdrawal of the south German states from the war. Ultimately, the North German Federation sued for peace, and was forced to cede the left bank of the Rhine to France, a humiliating defeat for the North Germans.
The next decade transformed Europe. France, now flush with power from their unexpected victory over the North German Federation, supported a republican coup in Belgium. The new republican government severed ties with Britain, and invited French forces into the country to restore order. The French forces never left, and a year later the country’s government agreed to be annexed by the Empire of France. Following this, the Netherlands, who at the time found itself without allies, became France’s next target. A short war forced them to cede their portion of the Rhine, to the English Channel, to France. Meanwhile, in Germany, Bismarck skillfully managed to direct the blame for their defeat on the Kaiser, strengthening his own position. He used this power to unify Germany, using the threat of French dominance as a reason to unite.
The final French conquest in Europe was also the one that brought the continent closest to war. The French, employing similar tactics to that which they used in Belgium, ignited a French Nationalist rebellion in Western Switzerland. When these rebels declared themselves part of France, French troops moved into several small border areas. This violation of Swiss neutrality nearly caused Britain and Germany to declare war, but the uncertain circumstances of the incursion prevented an outright war. With Switzerland falling apart, a conference was held in Munich on the issue of Switzerland. Ultimately the European nations decided to partition the country along ethno-linguistic lines.
While France stood ascendant in Europe, the cost of this expansion gave rise to a coalition of nations against the French. Bismarck, using his increased powers, managed to secure an alliance with the United Kingdom, and slowly the battle lines in Europe were drawn.
