Romania's attendance~
After securing relations with neighbours around like Serbia, Croatia and Montenegro Romania knew its time for her greatness. After several social reforms and establishment of a Centre of Trade In Bucharest, Romania enlarged the military preparing.
As to the First Central European War emerged, Romania sided with Germany and Russia against powerfull armies of Austro-Hungary and Italy.
This is what happened:
After the war, Alexandru Ioan Cuza gained for Romania, Transylvania as vassal, Carpathia and Partium and Banat.
While our friends, Russia and Germany were busy with Ottoman Empire , Persia and other asian nations, we managed to conquer Bulgaria. We took Burgas and Silistria, so we could have more acces to the Black Sea.
Convincing Serbia to accept our suveraignity and later to be part of our realm, betrayed by Montenegro in the CEW 1, lost Croatia's frienship due to her vassalization by Austro-Hungary, Romania only had to annex Transylvania in order to keep a high centralized society.
Being capable of supporting an army of 60.000 troops, and because of rising economy due to the Centres of Trade in Wallachia and Burgas, Romania quickly developed and strengthen the forts of her realm.
Among those things, we are masters of trade, owning monopolies not only in our lands, but in Thrace, Wien, and London.
