Romania

Romania is a playable (★★) [1865] (★) [1914] faction with a Normal (1865) or Hard (1914) difficulty and is a Balkans nation.

A.D 1865
Romania sides with the Monarch states so its allies are the United Kingdom, Spain, Ottoman Empire, Papal States, Prussia, German Confederation, Bavaria, and Bulgaria. It borders the Austrian Empire, the Russian Empire, a very narrow border with Montenegro and Bulgaria. Its general is Ioan Culcer (Infantry) Its primary goal is to defeat Austria and take care of Russia as they'll be distracted on Prussia or the Ottoman Empire.

A.D 1914
Romania now sides with the Entente and its allies are the United Kingdom, France, the Russian Empire, Portugal, Italy, Greece, Serbia, Montenegro and Belgium. Its generals are Alexandru Averescu (Cavalry) and Carol I of Romania (Infantry) You should immediately try to neutralize Bulgaria as they're a major threat for you and your allies and then you should try to either go invade Austria-Hungary or the Ottoman Empire.

A.D 1917
Romania is in Albania for some reason and its new Entente allies are the United States, Peru, Brazil, Libya, and Morocco. Its generals are Constantin Cristescu (Cavalry) and Alexandru Averescu (Cavalry). You should adopt the same strategy as 1914 and kill Bulgaria.
