Siena is a small one-province minor destined for annexation. In history Siena's independence ended with the Battle of Marciano and thus was absorbed into the Grand Duchy of Tuscany. Can you change the fate of Italy?

Starting Position

Siena starts with a university and an aggressive Papal States next door. In order to survive 5 years Siena must ask the Papal States for military access and declare war on Urbino before any other Italian minors annex it. This is because Urbino is the most vulnerable target of all of the Italian minors, and is almost always conquered by a more powerful neighbour. After annexing Urbino warn every Italy nation except Venice (for obvious reasons) and Sicily (which starts under the sway of Aragon). Tuscany should be your next target because of the universities they own, but conquering any of the other OPMs nearby can put Siena on more equal footing with the local powers.


  • Survive
  • Annex Urbino
  • Become friends with Sicily and Aragon
  • Take down Tuscany ( for historical revenge)
  • Eat Italian minors
  • Pray that Aragon does not inherit Sicily
  • Form Italy

The first goal is easy once you annexed Urbino no change for tinies in Italy. Friends means giving military access as you can not afford gifts. Tuscany starts with a pretty good leader with military stats proceed with caution or gang up on Tuscany during a war. Eating minors is self-explanatory(peasant).

The Pope

Make friends with the Pope for several reasons. One, you're neighbors, Second, the Pope has decent armies enough to crush Siena at the beginning of the campaign. Third, the man with the awesome hat makes a better ally than enemy. It is like Chuck Norris better to have him on your side than against you right? Fourth, You're Catholic he's Catholic. One problem is the Pope has a hard to reach territory in France called Avignon with a level 3 fort. Treat the Pope as if he got 300,000 men or more.

Soon however you must destroy the Pope in order to unite Italy. When fighting the Pope attack fast and hunt the armies and siege. Don't let the Pope raise mercenaries. Avoid the that unpleasant situation by sieging every province he owns. A country can not buy soldiers if every province is under siege. Next is how to deal with Avignon the Level 3 fort in southeastern France owned by the Pope. There are two ways to deal with problem. One, receive military access and march after sieging the other provinces( so no Papal armies mess up your plan). However the fort will take forever to fall due to the amount of men you bring. This depends on how big your country is, and army force limits. I suggest sending 4,000-5,000 infantry with a general. Often the Pope has a soild size army in Avignon in the range of 3,000-4,000. Second way is after occupying all the other Pope's provinces to demand the release of the country of Avignon. My suggestion is have the Pope cede you the province. Avignon has the best fort early in the game for years plus a Tax Assessor which reduces inflation.

Forming Italy

Forming Italy is a pretty good challenge for any player. Uniting Italy is best done quickly before any blobs enter the area. Or Venice blobbing is always a concern. Italy loaded with rich provinces, fine base for expansion, and no big blobs to deal with. Well, Venice is no slouch but no military aggressive France, the bully Burgundy, no Turks, Poles, or Brits sieging your cities. That doesn't mean you sit still. No you control Italy first than the Mediterranean like the Romans.

National Ideas

Good National Ideas: are the following

Colonial Ideas are better used later in the game. Naval Ideas are super important as naval warfare in EU3 is pretty much a toss-up or just use a big fleet to sink the enemy. Trade ideas are necessary for trading if you want. Sending a few merchants is not bad at all.

The New World

With Colonial Range in NA that hinders the use of colonies ( design to keep out the Pope, Teutonic Order, and others would be conquistadors.). In Eu3 vanilla there is not range so establish colonies. What to colonize is the following

  • Caribbean Sugar Islands: Rich, easy to colonize, and easy to defend. Cuba with tobacco, cotton, and sugar is the best island.
  • East Coast of the USA: Good population value, rich in cotton, tobacco, and sugar. Friendly Indians.
  • Fernando Po: For the trip around Africa.
  • Cape Horn: Best provinces in Africa, good population, and good resources.

Avoid the grain, naval supplies, and fish. Unless the fish island is an important supply base like Diego Garcia, St. Helena etc. Colonize two colonies at a time. Do not overwhelm the resources of Siena.

Alliances Rules


  • Small German minors (minors can not help in war)
  • Small Italian minors (you want to eat these minors)
  • France (by all means keep France out of Italy unless you want to be suicidal)
  • Aragon (same reasons as France)


  • Venice (At least until you're stronger, and then break the alliance)
  • Savoy (Could lead to war with France)
  • Pope (Close neighbor dangerous but powerful)
