Wallachia strategy

From EU3 Wiki

As Wallachia the best strategy is to go along with the Ottoman's conquests. After a few months they will give you an alliance offer. Accept. Every time they declare war on someone join them and you could win some provinces. Be sure you won't lose because the Ottomans are a great power in the Balkans. When you have enough provinces and you could stand by your own cancel the vassalization with the Ottomans but try to remain ally (in order to simplify your next conquests).

Note: After you declare your independence try to annex Moldavia if you have the mod with Romanian Unification (Flavor or Magna Mundi IV).

Another strategy is the next one: Wait until the Ottomans ally with you then cancel vassalization and take over the Balkan Countries. Improve your economy - you can trade very effective through Thrace - and send some gifts to the Ottomans so that they would help you in every war.
