WW1 italy invades France

Italy originally a central power doesn't declare neutrality and decides to invade France (before prussia does)

How does this affect WW1?

It's a little complex.

**Major Caveat: Italy needs coal imports, and Germany may have to provide. This is a near disaster.

1. There will of course be a direct drain on French manpower and supply with a new front. It is unlikely however for an especially large number of troops to be required or for the Italians to find much success for quite a while. (Mountain fighting, etc)

2. More importantly, this prevents a major drain on Austria Hungarian manpower. The OTL AH-Italy front bleed like an Ulcer. This is bad news for the Russians, and likely brings increased numbers of German troops to the West.
Given the small frontage of the French-Italo front, it isn't impossible that Italy sends troops to the Eastern front. This can also extend or prevent the AH collapse.

3. The Mediterranean is suddenly a Central powers lake. This means that France has somewhat increased trade problems and may even face actions on its Mediteranean holding. The Royal navy will want to engage the HSF decisively in order to cover both naval fronts.

4. The colony war in North Africa is... more complex.

5. The Central powers have more time to avoid what ultimately squashed them: Manpower losses.
 
Another consideration; depending on timing, won't sizeable entente formations be cut off when their med supply lines are cut?
 
Prussia? is this meant to be pre-1900?
Prussia only changed to germany afther 1918 right?

could you elaborate?

Would england get involved when prussia doesn't invade trough belgium? Would the US?

Would a deal be possible with Italy afther it invaded france?

How would holland belgium and switzerland denmark react/respond to this?

No the German Empire was formed in 1871 after the victory over the French in 1870.
In some aspects You both are in right. In military matters it possible to distinguish between Navy and Army. After 1871 the Navy was matter of Germany, mostly because city states of Hamburg and Bremen. Army was mixed bag in three ways: 1) There was German Army (Deutsches Heer), what was based mostly on Prussian army. 2) Bavarians and Würtenbergians retained their army's in peacetime. 3) The war ministry that was responsible for German army was Prussian ministry of war, there was no German war ministry, even the post 1919 Weimar war ministry was based on Prussian one.

And Germany from late 19-th century to 1945 is most easily described as Prussia and pals.

So with Italy invading france, would germany soon follow or would they focus mostly on Russia for a bid avoiding the french fortifications. Aftherall Germany seemed more interested to expand east then west.

Would the war still take as long as it did OTL.
Would brittain still get involved?
With germany clearly having a better foreign minister, how would Italy respond with a german french chirmas truce complete with the singing and a soccer match. especialy considering it would be in the german alsace lorraine region, and many of the german soldiers speak french. (in this example the german militairy actual encourgages taking picture and sends them to the press of england, america and offcourse russia)

I imagine it depends on if the Italian offense was enough to weaken the German/French border. If so, no need to go through Belgium, less likely chance for British navy to blockade supplies to the alliance, and even if they did, it's possible more supplies come through the Mediterranean (though the British, I'd involved, would make it hard getting past Gibraltar). Either way, their manpower problem for the Western front is least temporarily solved, and they might not get bogged down with trenches.
 
would you assume that italy being a realistic threat France simply wouldn't have the force near the german border (needing to split up it's forces between the german and italian border)?
Is their a map somewhere where the troop positions where right before the war? Was France defending it's italian border?
 
If Italy is a member of the CP in WWI there will be no invasion of France, the overall plan was to leave a screening force in the alps and send the bulk of the army in Germany to fight in north France
 
Italy can't mount an offensive against the Alps without France being tied down in the north, and it's likely to be the exact same bloodbath as the Isonzo Front. Italy's only option to invade France is to invade Corsica or Tunisia (both Italian war goals) and neither option is going to be easy since it requires naval supremacy and could just as easily end up a Gallipoli-tier disaster.

France needed something like 4 divisions to hold down their Italian border, a drop in the bucket in terms of manpower.

I think france troops where tied down at the time with the german troops near the border (this event doesn't look inpossible)

If the Italians and Austrians can work together for a few days, they can cripple French naval power. This would force the RN to cover the Med too...while they might just send a lot of pre-dreadnoughts and hope for the best, that will be some major heartburn for the Admiralty.
 
Can I ask why Italy would even enter the war on the side of the Central Powers? Their most obvious territorial demands were for Istria, the South Tyrol, and Dalmatia and there is no way on earth that the Austro-Hungarians would have given Italy any of those areas, even if Italian participation would have helped with a CP victory.
IIRC the only reason that Italy even signed the Triple Alliance was because they were annoyed that France had pinched Tunisia before they could in the 1880's.
