Romania's Political Treaty

Romania had been allied with the Central Powers since 1882. When the war began, however, it declared its neutrality, arguing that because Austria-Hungary had itself declared war on Serbia, Romania was under no obligation to join the war. On 4 August 1916, Romania and the Entente signed the Political Treaty and Military Convention, that established the coordinates of Romania's participation in the war. In return, it received the Allies' formal sanction for Transylvania, Banat and other territories of Austria-Hungary to be annexed to Romania. The action had large popular support.
