The Battle of Bizani was fought between Greek and Ottoman forces during the last stages of the First Balkan War, and revolved around the forts of Bizani, which covered the approaches to Ioannina, the largest city in the region.

At the outbreak of the war, the Hellenic Army on the Epirus front did not have the numbers to initiate an offensive against the German-designed defensive positions in Bizani. However, after the campaign in Macedonia was over, many Greek troops were redeployed to Epirus, where Crown Prince Constantine himself assumed command. In the battle that followed the Ottoman positions were breached and Ioannina taken. Despite having a slight numerical advantage, this was not the decisive factor in the Greek victory. Rather, "solid operational planning" by the Greeks was key as it helped them implement a well-coordinated and executed assault that did not allow the Ottoman forces time to react.^[59] Furthermore, the bombardment of Ottoman positions was the heaviest in world history up to that time.^[60] The surrender of Ioannina secured Greek control of southern Epirus and the Ionian coast. At the same time, it was denied to the newly formed Albanian state, for which it might have provided a southern anchor-point comparable to Shkodër in the north.
