White Empire is a timeline which details the history of Russia and Europe as a whole after a White victory in the Russian Civil War.
Point of Divergence
Trotsky fails to conclude the agreement between the Red Army and Nestor Makhno's Revolutionary Insurrectionary Army of Ukraine for mutual support. Without the alliance between the Red Army and Makhno's Black Army, the latter doesn't send his army east and attack General Denikin's forces while they are on their march toward Moscow. With his supply lines fully intact, the Whites emerge victorious in the Battle of Orel and continue their push toward the capital. The loss at Orel prompts Trotsky to recall his forces sent to reinforce Petrograd back to the capital.
Without reinforcements, Petrograd falls to General Yudenich. Unfortunately for Trotsky, the recalled troops do not make it to Moscow in time, and Denikin's forces manage to capture the city. With the two biggest Red strongholds now in White control, the Bolsheviks are in dire straits, with the Red leaders eventually high-tailing out of Russia. Grand Duke Nikolai is crowned Nicholas III of Russia, however his power is reduced to that of a constitutional monarch with negligible power. This satisfies the traditionalists and democrats in addition to providing the nation with an untainted figurehead that the populace can rally around thanks to his popularity within Russia. A parliamentary democracy is set up in the Russian Empire modeled after the British system.
Pyotr Wrangel becomes the first Prime Minister, with others like Viktor Pepelyayev and Pavel Milyukov being part of his coalition cabinet. The other White generals (Anton Denikin, Alexander Kolchak, Nikolai Yudenich, etc.) set up a Privy Council to "advise the government", but it is simply a way for the generals to retain some measure of control over the government. Kolchak becomes a figurehead leader of the political right. The Empire is still quite fragile, with corruption and instability still rampant, and the assassination of Prime Minister Wrangel in 1927 by a radical revolutionary doesn't help matters. Milyukov succeeds him as Prime Minister. Tsar Nicholas III dies in 1929 and is succeeded by Grand Duke Kirill Vladimirovich, who is crowned Tsar Cyril I of Russia.
Not long after, the stock market crashes and the world is plunged into the Great Depression. Prime Minister Milyukov tries his hardest to hold things together, but the country continues down the road to another civil war. At the behest of Tsar Cyril, Alexander Kolchak steps in to "re-establish order" to prevent the Empire from collapsing and becomes the de facto dictator of the Russian Empire. Under Kolchak, the Empire retains a sort of stability, but the military strongman turns his attention to those that could threaten his position in Russia. The Privy Council was dissolved with Denikin, Yudenich, Kutepov and much of the army high-command purged and Kolchak dissolved the Duma for the duration of his rule, declaring himself "Supreme Ruler" of Russia.
To the west, the Weimar Republic was on its last legs. The nations nearly imploded after the death of Paul von Hindenburg, the country's Chancellor. To prevent civil war, the Reichswehr, backed by the German National People's Party, moves in to "restore order". This new government takes steps to re-militarize Germany. The military government eventually transfers control to a civilian administration, which is filled with right-wing revanchist monarchs. After the restoration of the Hohenzollern monarchy, Germany begins its plan of revenge for the Treaty of Versailles.
After Kolchak's death in 1935, Alexander Lvovich Kazembek of the 'Union of Mladorossi" succeeds him. The handsome and charismatic Kazembek proves to be a popular leader with his promotion of modernization and traditionalism as well as his reinstitution of the State Duma, which allows him to consolidate power within the government, transforming the Russian Empire into a one-party state by 1938. Tsar Cyril dies the same year and his son, Grand Duke Vladimir Kirillovich, is crowned Tsar Vladimir IV. During this time, Kolchak continues its relations with the restored revanchist German Empire, entering in a military alliance and directs his attention to the lost territories of the Empire; Poland, Finland and the Baltics, all the while building up Russia's armed forces.
In 1943, the combined forces of Germany and Russia invade Poland on the 13th of March. France declared war two days later, hoping many would rally around them against the two nations. They didn't; although the League of Nations almost unilaterally denounced the invasion, nobody was willing to get involved in another major European war, not even Britain, who opted to remain neutral for fear of losing Germany as a trade partner. Poland is subdued, and Germany successfully annexes the territory taken from them in the Treaty of Versailles while the Russians outright annex Poland. While Germany diverts its attention westward, Russia escalates the war by invading and occupying the Balkans and invading Finland, as well as intimidating Romania into giving up Bessarabia.
The Balkans are re-annexed into the Russian Empire and the Finnish fall to the Russian steamroller in November of 1943. To the east, Japan is beginning to lose their war in China. There were several border clashes between the Russian and Japanese military on the Russo-Manchurian border between 1938 and 1940 and many believed the Japanese were eyeing the Russian Far-East. After the Russian victory in Europe, Kazembek takes advantage of Japan's position in the war and invades Manchuria, making the Russian Empire and the United States of America allies in the war against Japan. After the Japanese were forced from Manchuria, the Russians consolidated their gains and annexed the territory, moving on to subjugating the fledgling Mongolian state while the Americans plan their invasion of the Japanese home islands. In addition to Manchuria and Mongolia, the Russians annex several districts in the north of East Turkestan.
After Russia's conquests, the Empire entered a golden age. This era sees the consolidation of gains from the Second World War and state-enforced Russification of the annexed territories, where resistance to Russian rule is utterly crushed. In 1951, Kazembek defers leadership of the Russian Empire to Anastasy Vonsyatsky, who leads Russia until his death in 1977. After Vonsyatsky's death, parliamentary democracy and legalization of other political parties is reinstated, and the still-popular Union of Mladorossi reconstitutes itself the Russian National Party and wins the country's first election in decades.
As per OTL, Mussolini is able to rise to power. He continues ruling much the same as OTL, but is killed along with Galeazzo Ciano by an Anarchist bomb in 1936. After his death, Il Duce is succeeded by Marshal Italo Balbo, who continues Italy's expansion. During the buildup to the Second World War, Italy's military modernizes and Balbo mounts successful military campaigns in Greece and Yugoslavia, subjugating both states and absorbing them into the Empire. When war broke out and France was outmatched, Balbo took the opportunity and invaded France the same time as Germany, annexing Savoy and Nice, as well as negotiating the purchase of British Somaliland from the United Kingdom.
Balbo continues ruling Italy until his death in 1988, which sees King Vittorio Emanuele IV step in to try and re-establish parliamentary democracy and illegalize the Fascist Party. However, a counter-coup led by the Fascist Party leads to the king's arrest. Vittorio Emanuele's 16 year-old son, Emanuele Filiberto, famously makes a speech at Palazzo Venezia, denouncing his father's attempt to usurp power in Italy and proclaiming support for the Fascist Party, calming the civil conflict within the country. Afterwards, Emanuele Filiberto is crown King of Italy while the Fascist Party establishes a kind of authoritarian democracy, still keeping an iron grip over its Empire.
Since King Reza Shah is not deposed in an Allied invasion like in OTL, he rules until his death in 1944, when his son, Mohammed Reza Pahlavi, takes power. However, without a Cold War, the CIA and MI6 do not back a coup to depose Prime Minister Mosaddegh, thereby leaving the monarchy in Iran as a figurehead post and butterflying away the Iranian Revolution of 1979.
