The Balkan Wars refers to a series of two conflicts that took place in the Balkan States in 1912 and 1913. In the First Balkan War, the four Balkan States of Greece, Serbia, Montenegro and Bulgaria declared war upon the Ottoman Empire and defeated it, in the process stripping the Ottomans of its European provinces, leaving only Eastern Thrace under the Ottoman Empire's control. In the Second Balkan War, Bulgaria fought against all four original combatants of the first war. It also faced an attack from Romania from the north. The Ottoman Empire lost the bulk of its territory in Europe. Although not involved as a combatant, Austria-Hungary became relatively weaker as a much enlarged Serbia pushed for union of the South Slavic peoples. The war set the stage for the Balkan crisis of 1914 and thus served as a "prelude to the First World War".By the early 20th century, Bulgaria, Greece, Montenegro and Serbia had achieved independence from the Ottoman Empire, but large elements of their ethnic populations remained under Ottoman rule. In 1912, these countries formed the Balkan League. The First Balkan War began on 8 October 1912, when the League member states attacked the Ottoman Empire, and ended eight months later with the signing of the Treaty of London on 30 May 1913. The Second Balkan War began on 16 June 1913, when Bulgaria, dissatisfied with its loss of Macedonia, attacked its former Balkan League allies. The combined forces of Serbian and Greek armies, with their superior numbers repelled the Bulgarian offensive and counter-attacked Bulgaria by invading it from the west and the south. Romania, having taken no part in the conflict, had intact armies to strike with and invaded Bulgaria from the north in violation of a peace treaty between the two states. The Ottoman Empire also attacked Bulgaria and advanced in Thrace regaining Adrianople. In the resulting Treaty of Bucharest, Bulgaria managed to regain most of the territories it had gained in the First Balkan War. However, it was forced to cede the ex-Ottoman south part of Dobruja province to Romania.The Balkan Wars were marked by ethnic cleansing with all parties being responsible for grave atrocities against civilians and helped inspire later atrocities including war crimes during the 1990s Yugoslav Wars.

Ioannina (Greek: Ιωάννινα Ioánnina [i.oˈa.ni.na] (listen)), often called Yannena (Γιάννενα Yánnena [ˈʝa.ne.na]) within Greece, is the capital and largest city of the Ioannina regional unit and of Epirus, an administrative region in north-western Greece. According to the 2011 census, the city population was 65,574, while the municipality had 112,486 inhabitants. It lies at an elevation of approximately 500 metres (1,640 feet) above sea level, on the western shore of Lake Pamvotis (Παμβώτις). Ioannina is located 410 km (255 mi) northwest of Athens, 260 kilometres (162 miles) southwest of Thessaloniki and 80 km (50 miles) east of the port of Igoumenitsa in the Ionian Sea.

The city's foundation has traditionally been ascribed to the Byzantine Emperor Justinian in the 6th century AD, but modern archaeological research has uncovered evidence of Hellenistic settlements. Ioannina flourished in the late Byzantine period (13th–15th centuries). It became part of the Despotate of Epirus following the Fourth Crusade and many wealthy Byzantine families fled there following the sack of Constantinople, with the city experiencing great prosperity and considerable autonomy, despite the political turmoils. Ioannina surrendered to the Ottomans in 1430 and until 1868 it was the administrative center of the Pashalik of Yanina. In the period between the 18th and 19th centuries, the city was a major center of the modern Greek Enlightenment. Ioannina was ceded to Greece in 1913 following the Balkan Wars.

The city is also characterized by various green areas and parks, including Molos (Lake Front), Litharitsia Park, Pirsinella Park (Giannotiko Saloni), Suburban Forest. There are two hospitals, the General Hospital of Ioannina "G. Hatzikosta", and the University Hospital of Ioannina. It is also the seat of the University of Ioannina. The city's emblem consists of the portrait of the Byzantine Emperor Justinian crowned by a stylized depiction of the nearby ancient theater of Dodona.
