World War I and the Treaty of Tehran
The First World War began on July 28, 1914, with a German declaration of war on France. Each nation swung for a knockout blow at the same time. France tried to break into Germany through Alsace Lorraine, while Germany went at France through Belgium and Luxembourg. The German effort was more successful, as they were able to break into France through the light fortifications in the north. The French desperately tried to stop them, but the Germans successfully managed to brush aside the French division defending Paris and seize the city. The French government manages to safely relocate, but it is obvious to all that the capture of Paris has crushed the French spirit. The Germans then take a forced logistical pause on the western front. The Russians see how quickly the French were defeated, and combined with the German victory at Tannenberg, decide to pull out of the war before they can be occupied by Germany. They make a separate peace at Brest-Litovsk. The Russians and Germans pledge not to attack each other, and the Russians give up some land to Germany. This allows the Germans to move forces to the western Front to finish off the French forces and their British allies. A final German offensive crushes the remnant of the French Army, and the British evacuate their forces back to England. The French sign a peace at Vichy, giving up Franche-Comte, and the Champagne-Ardenne, plus some reparations. The Ottomans, seeing their chance to make easy territories gains, which they hope will restore their lost glory, join the war on the side of the Central Powers. This pushes the Italians to join the war on the side of the Central Powers. The British ship forces to Egypt to counter the threat of the Ottoman Empire, but it takes time since the German, Italian, and Ottoman navies make transporting forces a real dangerous affair. In 1915, the Ottoman Empire has successfully conquered Saudi Arabia, Transjordan, British Palestine, and much of the Persian Gulf and part of Iraq, despite resistance from the British. 1916, the Ottoman Empire has conquered Iraq and some of Persia (Iran), but more territorial gains are becoming increasingly hard, as the long distances and British forces are playing havoc with logistics. Thailand has declared war on the Allies. The USA has declared a backing-away from the war. Thailand conquers much of Denmark and Japanese Asian colonies. 1917, the Allies surrender. In a Central Powers meeting to discuss negotiation. Germany cries for a limited Allied sphere of influence, as do the Ottoman Empire and Austria-Hungary. Thailand and Bulgaria, afraid of revenge, cry for Allied blood. But they are forced to cooperate under strong influence. A meeting in Tehran between the two sides. The major agreements are to give up all colonies in exchange for life, and to give up many strategic chokepoints. The Ottoman Empire now spans across all of the Middle East and Iran, Central Asia up to Kazakhstan, Egypt and Libya, and Cuba. The German Empire spans across Western and Central Europe, minus Britain and including Ireland, and a lot of Africa. Thailand is now an empire as well, spanning Indochina, Indonesia, and even Taiwan. Austria-Hungary controls vast Latin American and African colonies, some Pacific Islands. This treaty is clearly unfair, but the Allies are forced to agree in order to survive.
The Coming Shock
The economies of the Central Powers were going madly like an engine before the humongous crash in 1925. By 1924, German economy size was close to thrice the size of its economy in 1900. Austrian-Hungarian economy and Turkish economy were also going smoothly. This had let to the loose policies, and speculators, and other firms and men were on the loose. Too much fooling with the market led to a general collapse of the economy. German dollars were worth 2 USD in our current rate in OTL, before the collapse. By the end of 1925, where the main indexes had dropped below measure, it was worth little more than 0.4 USD. Thousands were left in poverty. The King pledged to improve the economy. In Turkey, where the Ottoman Franc was worth 1.2 OTL USD, a large collapse also occurred. The dollars survived, but not the indexes. In the USA, things were less frightening, but still it was troubling. The trouble left after three years of tormenting, where the American and German engines churred again.
Famine and Plague in Colonies
In most African colonies, plagues and famine gripped the continent. Those were ignored, but it set one of the reasons for the later African rebellions.
Socialism in Russia, Mongolia, Korea, China and Japan
A socialist movement finally succeeded in taking power in Russia. They were sneered at, but ignored. Fortunately, most Socialist leaders followed the policies of the rest of the Grand Alliance.
The Grand Alliance
The USA had gained lots of power lately, and had enough strength to found an alliance of its own. Already, Canada, Russia, Sicilian Italy and Britain had expressed interest in fighting the Central Powers. Soviet Russia was not content to be stuck in the snowy wastelands of Siberia, and Canada wanted to have a foothold in Europe as a step to power. Sicilian Italy was driven by a simple hope of restoring their own nation. Britain wanted to be empire again. The US simply wanted power. The Asian allies, Qing China and Japan, each had their own agenda to be empire. In Asia, after all, Thailand wasn't that dominant as Germany was in Europe. It seemed sensible to start an alliance in Asia. Emperor He-Su of Japan, King Ga-Wa of Qing, President Mark Snappers of the US and some former colony governors from Europe, met in Tokyo in 1934. It was largely in secret, and the Americans were told that President Mark had gone to Britain for a trade pact. On day 2 of the 5-day conference, Soviet Premier Lenin also came to the meeting. China and Japan, it was agreed, were to fight Thailand, and the colonies of Asia would be given over to them. The Soviet Union would not interfere with the Asian allies. It would deal with Bulgaria, Turkey and Austria-Hungary instead. America would step in at appropriate times to assist.
In 1935, another secret meeting was held between Britain, Sicilian Italy and the USSR, lead by PM John Hans, President Mary Glithus, and Premier Lenin attended. The USA also attended soon, with President Mark coming.
World War II
Start of War
On 17th August 1936, the USA arranged a general meeting among the Allies in Vladivostok, USSR. The Japanese Empire, Qing Chinese Dynasty, Britain, Sicilian Italy, USSR and the USA, 6 countries in all, plan a battle plan named "Grand Operation Global Corners" after the plan's vastness. On August 19th, 1936, the USSR invaded Austria-Hungary and Bulgaria. Sicilian Italy, which was secretly filled with British and American troops, invaded German Italy. Britain started its plan of harassing German France. The USA quickly started arms shipments to independence movements in Australia, New Zealand, South Africa, Israel ("Palestine") and India. On the Eastern Front, Austria-Hungary was taken by surprise, as was Bulgaria. China and Japan ambushed Thailand on the 25th. The Ottoman Empire, closely connected to the losing Eastern Front powers, wanted to hold the line as bombers ravaged French and German bases, and 100,000 troops landed in France on September 27th. Germany was taken by surprise but forced a retreat soon. Fierce fighting in the East. Bulgarian lines are collapsing as Russian and recently Chinese troops crash into Europe, and as they invade the Ottoman Empire. The Japanese troops are landing in Thailand, and its colonies are rebelling. Malayan rebels soon launch a partial assault at local troops. On the 3rd of October, after months of bombing and surprise attacks, 20,000 troops finally land in Naples. Germany is shocked but pulls out of Southern Italy to defend in France. Meanwhile, American troops have shock-attacked Spain and Portugal. In Central Asia (Known as "the Pan-Persian Front"), China has officially interfered. The forces take some land soon. In December, some of Portugal and France is now Allied territory.
By 1937, American troops have interfered in the Middle East and is fighting with the Ottoman Empire. Bulgaria is retreating, while Austria-Hungary is standing strong. American troops land in Nigeria, Angola, South Africa, Madagascar, and Algeria. Chinese troops and Japanese troops are invading India and Thailand. There is a revolt in Austro-Hungarian Mexico, and the revolt succeeds as the new United TransAmerican Republic. Soviet troops have taken Central Asia. Germany is holding much of Central Europe, but not France and Portugal. Thailand is failing, as is Bulgaria.
Algerian, Nigerian and Angolan locals are revolting under the help of the Americans. Meanwhile, Mexico is rising to fight the Central Power troops in South America. Mexico, which was once a small state comprising only Lower California and parts of Northern and Eastern OTL Mexico, North-Western Cuba and Guatemala, starts aggressing. By 1939, much of Europe is liberated.
