What happened August 1916 AD

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.

In the summer of 1916, after the Battle of Doberdò, the Italians captured the town of Gorizia. After this victory, the front remained static for over a year, despite several Italian offensives, centred on the Banjšice and Karst Plateau east of Gorizia.

In 1916, Romania entered World War I on the side of the Allies. In doing so, Romania's goal was to unite all the territories with a Romanian national majority into one state. In the Treaty of Bucharest (1916), terms for Romania's acquisition of territories within Austria-Hungary were stipulated.

On 27 August 1916, the Romanian Army launched an attack against Austria-Hungary, with limited Russian support. The Romanian offensive was initially successful in Transylvania.
