What if Italy joined the Central Powers in late 1914 or early 1915? [maybe the pods can be from the late 19th century to a better Central Power performance in WW1's 1st months and concessions]
Here is a possible timeline: [Based in format on https://www.alternatehistory.com/discussion/showthread.php?t=304673]
December 1914: The Central Powers offer Italy concessions in expectation of an Italian entrance into WW1 on their side.
June 1915 [about]: Italy declares war on France and Britain before being followed by Russian, Japanese, Serbian, Montenegrin and Belgian responses. Gallipoli is evacuated and the troops reinforce the Middle East while Indians and reinforcements conquer East Africa.
10 August 1915: When the Central Powers invade Serbia, the Serbs and Montenegrins get themselves surrounded but fight for three months before surrendering. The French maintain their defence line in the Alps even with several Italian offensives and raids.
October 1915: The Germans continue their Russian offensive and take Riga. The offensive goes slightly longer than reality before stopping at Estonia. Back in Egypt, a joint Italian-Ottoman-Austrian offensive barely succeeds before being repulsed by reinforcements from newly conquered Italian and German African colonies.
February 1916: Germany launches its offensive on Verdun while the Entente launches an offensive in North Africa to defeat the Italians simultaneously. Austria-Hungary has to reinforce the Eastern Front and free up German troops for the Western and Mediterranean fronts, but luckily, the former empire could devote most of its strength to the east.
June 1916: Despite the expected defeat of Russia, the Brusilov Offensive causes some damage to the Austro-Hungarian Army before being stopped. The Entente cleans up North Africa before reinforcing Egypt and the west.
August 1916: After the loss of Verdun, the Entente counteroffensives to retake the city and the Somme become costly pyrrhic victories. The Ottomans retreat from Egypt, but conquer Azerbaijan, Iran and Mesopotamia. Negotiations for the entrance of Greece and Romania joining the Entente take place, but become futile after their offensives wind down over the winter.
spring 1917: Revolution occurs in Russia while the French-British offensive on the Western Front fails. However, plans are made for an invasion of Sicily in the aftermath of the offensive's failure.
August 1917: The Entente launches offensives against Belgium, Sicily and Egypt. The first fails, but the second succeeds and it seems that Italy might be knocked out of WW1. In Russia, the failure of its final offensive causes it to sign for peace later in the year, despite the Entente's successful invasion of Sicily, Sardinia and southern Italy.
spring 1918: Austro-Hungarian and Italian troops are pushed back until Rome is defended successfully although the German offensive in the west succeeds, causing WW1 to end in summer. If not, the Entente knocks Italy out of WW1 in 1918 and gets Greece on their side. [Possible with American intervention.]
1919: The Germans retreat from their western front defences for good while internal conditions combine to compel their surrender by the end of the year. The same applies to the other Central Powers.
