In 1700, Charles II of Spain was the last Habsburg King of Spain, and controlled the vast possessions in Italy, Spain, Flanders, the New World and in the Philippines. In his will, he gave control of Spain to a Bourbon, who was Philip, duc d'Anjou. His will called for the crowns of Spain and France to not be united. But the reigned Louis XIV of France took this as a union of the Crowns, anyway. Thus, the War of the Spanish Succession began. What would happen, if France won this war?
Differences between OTL and Alternate History
The point of divergence was at the Battle of Blenheim on August 11, 1704. In OTL, Louis XIV loses miserably and loses his chance to conquer one of his most powerful foes, Austria. But, in this Alternate History, they do win the Battle of Blenheim. French forces defeat Austria, then the Holy Roman Empire, and then even Britain itself.
The Battle of Blenheim
In the midst of the Battle of Blenheim in Bavaria, French, Spanish and Bavarian forces are fighting against a combination of Austrian, Holy Roman and Flemish forces. Marshal Eugene of the French forces finds a weak point in the Allied lines and attack, throwing everything they have into that attack. They succeed in scattering the Allied forces into two; one to the south and one to the north. Incoming Bavarian reinforcements attacked the northern Allied forces and destroyed that cluster, while the remaining French and Spanish force attacked the one to the south, leaving the path to Vienna wide open.
The triumphant French and Spanish forces marched to Vienna, and besieged the city on September 2, 1704. The city fell on November 1, 1704. The Grand Alliance that had come together to fight France and Spain had lost its most powerful member, and each of the Allies made peace treaties with France and Spain.
The Congress of Toulouse
After the defeat of the Grand Alliance, a Congress was held in Toulouse, France to discuss what would happen with Europe. Louis XIV himself showed up at the Congress, and there was great debate. In the end, a few things happened. The Crowns of Spain and France were united, and was given the Spanish Netherlands (present-day Belgium) and the Dutch Republic. The colonial possessions were stripped from the new Kingdom of Western Europe, and ceded to Britain. Only the island of Hispanola and Cuba remained in the Western European hands. Austria, though defeated, was restored and given control over Italy,(excluding Savoy-Piedmont and Sicily) while Bavaria was given control over Germany. The great Kingdom of Poland was partitioned between Russia, Germany and Austria. Also, for protection, the Scandinavian countries of Denmark, Norway, Sweden and Finland were all united in the Grand Kingdom of Scandinavia. Russia, who now felt isolated and alone, turned toward their traditional enemies, the Ottomans and made a formal alliance with them. The balance of power had shifted greatly, but it was still balanced.
With the balance of power in the world greatly changed, the Kingdom of Western Europe, ruled from Toulouse, became a world power, only rivaled by Great Britain, whose colonies were greatly expanded. In 1714, Savoy-Piedmont and Sicily apply to enter the Kingdom of Western Europe. Louis XIV accepted the application. Things go smoothly for a few decades, as Louis XIV claims that the Kingdom of Western Europe was a "satisfied power". Britain did not believe such nonsense and jumped at the chance to make war or blockade the KWE. Britain made an alliance with Austria, Russia and the Ottoman Empire, while Louis XIV made a pact with Germany.
The World begins War
On August 8th, 1730, the new Louis XV was strolling through the Palace of Versailles in Paris on a tour of the KWE. A member of the radical Sicilian group The United Sicilian Succession Alliance rushed up to Louis XV and shot him twice. Miraculously, Louis XV lived, but Louis XV automatically ordered the execution of the assassin, whose name was Giuseppe Mazarola. An investigation was started in the KWE, and it was found that Great Britain had supported the group. The KWE automatically declared war on Great Britain, while Great Britain did the same to the KWE a day later. On August 10th, Austria declared war on the KWE, and Germany and the KWE did the same to Austria. On August 12th, Austria and Great Britain began mobilization of their armies, while Austria and Great Britain declared war on Germany as well. Germany and the KWE begin mobilization on August 13th. Russia and the Ottoman Empire remain uncertain and stay neutral for now.
World War I
Russia and the Ottoman Empire begin partial mobilization, with Russia concentrating their mobilized armies along the German border. Germany takes this as an act of war, and declares war on Russia. Russia and the Ottoman Empire declare war on Germany, while Germany declares war on the Ottoman Empire. On August 22th, Russia began the invasion of eastern Germany, with help from the Austrians ans the Ottomans. Austrian forces in Italy attacked Marseilles that ended in a 167-day siege, after overrunning the province of Savoy-Piedmont. British forces also indirectly attacked Bordeaux. On August 30th, the Russian army met up with the German army in former Bavaria, outside of Munich. The battle raged for 3 months, Russia nearly taking Munich several times. However, the Russian army was repulsed and they retreated back into Austria.
The Battle for Constantinople
The KWE sent its powerful navy from Marseilles on September 11th under the shroud of night. The navy was heading for the easiest place to attack from sea, the capital of the Ottoman Empire, Constantinople. The Ottomans caught wind of this, and they began to heavily fortify the Dardanelles, as well as Constantinople itself. When the navy arrived on September 20th, the capital was a virtual fortress. The navy landed, but it was a tough battle. They fought their way into Constantinople, but they were eventually repulsed.
The Second Battle of White Mountain
With the Russian forces retreating, the German army quickly followed after them, and the Germany army blazed a huge path through Austria, destroying everything in the path. In Bohemia, the Russian army met against the German army at White Mountain on October 15th. It was the bloodiest battle of the war so far, and over 6,000 soldiers died. Germany was defeated, and they were forced to retreat back to Munich. This victory raised Russian and Austrian morale, and allowed them to send reinforcements to Constantinople, just in case of another attack.
With the Western European navy fleeing from Constantinople, the British sent their fleet to intercept them at Gibraltar. The British had taken over Gibraltar and now virtually controlled the opening to the Atlantic Ocean. The Battle of Gibraltar toke place on November 4th, with the vastly superior of Britain easily outnumbering the much smaller Western European Navy, the Western Europeans were crushed, and lost the majority of their navy. Whatever survived limped back to Marseilles, where the remainder of the French navy was crushed by the besieging Austrians. Western European morale had reached a new low.
Restart of War
The Western Europeans called a 2 month truce. On January 4th, at the continuation of the war, Marseilles fell to the Austrians. However, at about the same time, the German army had began to invade Russia from East Prussia.
